The SP230A, SP235A/B, SP236A/B, SP240A/B, and SP241A/B feature ashutdown mode which reduces device power dissipa-tion to less than 5µW. All feature low power CMOS operation, which is particularly beneficial in battery-powered systems. The SP235A/B use no external components and are ideally suited where printed circuit board space is limited.All products in the Series include two charge pump voltage converters which allow them to operate from a single +5V supply. These converters convert the +5V input power to the ±10V needed to generate the RS-232 output levels. An internal charge pump converter produces the necessary –12V supply. All drivers and receivers meet all EIA RS-232D and CCITT V.28 specifications.The Series are available for use over the commer-cial, industrial and military temperature ranges. They are packaged in plastic DIP and SOIC packages. For product processed and screened to MIL–M–38510 and MIL–STD–883C require-ments, please consult the factory.THEORY OF OPERATIONThe SP230A/B–241A/B series devices are made up of t hree b asic c ircuit b locks –1) t ransmitter, 2) r eceiver and 3) charge pump. Each model within the series incorporates variations of these circuits to achieve the desired configuration and performance.Driver/TransmitterThe drivers are inverting transmitters, which accept TTL or CMOS inputs and output the RS-232 signals with an inverted sense relative to the input logic levels. Typically the RS-232 output voltage swing is ±9V. Even under worst-case loading conditions of 3kΩand 2500pF, the output is guaranteed to be ±5V, which is consistent with the RS-232 standard specifications. The transmitter outputs are protected against infi-nite short-circuits to ground without degradation in reliability.The drivers of the SP230A, SP235A/B, SP236A/B, SP240A/B and SP241A/B can be tri-stated by using the SHUTDOWN function. In this “power-off” state, the output impedance will remain greater than 300 Ohms, again satisfying the RS-232 specifications. Should the input of the driver be left open, an internal 400kΩ pull–up resistor to VCCforces the input high, thus committing the output to a low state.The slew rate of the transmitter output is internally limited to a maximum of 30V/µs in order to meet theTable 1. EIA Standards Definition 元器件交易网Charge Pump Output Loading versus VCC; a) V+; b) V–ENABLE Input (EN)The SP235A/B , SP236A/B , SP240A/B, and SP241A/B all feature an enable input (EN),which allows the receiver outputs to be either tri–stated or enabled. The enable input is active outputs. This can be especially useful when the receiver is tied directly to a microprocessor data bus.Protection From Shorts to >±15VThe driver outputs are protected against shorts to ground, other driver outputs, and V + or V -.For protection against voltages exceeding ±15V,two back–to–back zener diodes connected to clamp the outputs to an acceptable voltage level are recommended. (Refer to Figure 3.)Improved Drive Capability for Mouse ApplicationsEach of the devices in this data sheet have improved drive capability for non-standard ap-plications. Although the EIA RS-232D stan-dards specify the maximum loading to be 3k Ωand 2500pF, the SP230A , SP234A , SP235A/B ,SP236A/B , SP237A , SP238A , SP240A/B, and SP241A/B can typically drive loads as low as 1k Ω and still maintain ±5V outputs. This feature is especially useful when the serial port is in-tended to be used for a “self-powered” mouse.In this case the voltage necessary to operate the circuits in the mouse can be derived from the RS-232 driver output as long as the loading is ≥1k Ω (refer to Figure 4). For applications which even exceed this requirement, drivers can be connected in parallel, increasing the drive capa-bility to 750Ω, while maintaining the ±5V V OH and V OL levels (refer to Figure 5).Figure 3. High Voltage Short Circuit ProtectionFigure 2. Charge Pump Voltage Inverter output impedance of V + and V -, which will degrade V OH and V OL . Capacitor values can be as low as 1.0µF.Shutdown (SD)The SP230A , SP235A/B , SP236A/B , SP240A/B and SP241A/B all feature a control input which will disable the part and reduce V CC current typically to less than 5µA, which is especially useful to designers of battery–pow-ered systems. In the “power–off” mode the receiver and transmitter will both be tri-stated.V + will discharge to V CC , and V - will discharge to ground.For complete shutdown to occur and the 10µA current drain to be realized, the following con-ditions must be met:• +5.00V must be applied to the SD pin;• ENABLE must either 0V, +5.0V or not connected;• the transmitter inputs must be either +5.0V or not connected;• V CC must be +5V;• Receiver inputs must be >0V and <+5VPlease note that for proper operation, the SD input pin must never be left floating.Table 2.

Parallel DriversWake-Up FeatureThe SP235B , SP236B , SP240B and SP241B have a wake-up feature that keeps all receivers in an enabled state when the device is in the shutdown mode. Table 2 defines the truth table for the wake-up function. Timing for the wake-up function is shown in Figure 6.If the SP235B , SP236B , SP240B and SP241B are powered up in the shutdown state (SD driven high during V CC power up), the part must remain in a powered on state for a minimum of 3ms before the wake-up function can be used. After the 3ms wait time, there is a 2ms delay time before data is valid for both enable and disableFigure 6. Wake–Up and Shutdown Timing元器件交易网of the charge pump. If the SP2XXB is powered up with SD low, then only the 2ms delay time will apply (refer to Figure 6). Under normal operation, both the wait time and delay time should be transparent to the user.With only the receivers activated, the device typically draws less than 5µA (10µA max) sup-ply current. In the case of a modem interfaced to a computer in power-down mode, the RI (ring indicator) signal from the modem would be used to “wake up” the computer, allowing it to accept the data transmission.After the ring indicator signal has propagated through the SP2XXB receiver, it can be used to trigger the power management circuitry of the computer to power up the microprocessor and bring the SD pin to the SP2XXB low, taking it out of shutdown. The receiver propagation de-lay is typically 1µs. The enable time for V+ and V- is typically 2ms. After V+ and V- have settled to their final values, a signal can be sent back to the modem on the DTR (Data Terminal Ready) pin signifying that the computer is ready to accept and transmit data.All receivers that are active during shutdown maintain 500mV (typ.) of hysteresis.Varying Capacitor ValuesAs stated earlier, the capacitor values are some-what non-critical. Since they are an actual compo-nent of the charge pump circuitry, their value will affect its performance, which in turn affects the V OH and V OL levels. There is no upper limit for the value of any of the four capacitors; lower values will impact performance. C 1 and C 2 are respon-sible for the charge accumulation and can be reduced to 1µF; this will increase the output im-pedance of V + and V –. Reducing these capacitor values will limit the ability of the SP2XXA/B to maintain the dc voltages needed to generate the RS-232 output levels. Capacitors C 3 and C 4 can also be reduced to 1µF; doing so will increase the ripple on V + and V–.Typically each driver will require 1µF of capaci-tance as a minimum to operate within all specified parameters; if five drivers are active in the circuit,then C 3 and C 4 should be 5µF. In order to operateat these minimum values, the supply voltage must be maintained at +5.0V ±5%. Also, the ambient operating temperature must be less than 60°C.The capacitor values must be chosen to suit the particular application. The designer must bal-ance board space, cost and performance to maxi-mize the design. The capacitors can be polarized or non–polarized, axial-leaded or surface-mount.As the size and value decrease, so does the cost;however, the value should be chosen to accom-modate worst-case load conditions.IBM Modem Port InterconnectionsINTERFACE EXAMPLE – A MODEM ON THE IBM PC SERIAL PORTThe RS-232 standard defines 22 serial interface signals. These signals consist of ground lines,timing, data, control and test signals, plus a set of signals rarely used for a second data channel.Many of these signal lines are not used in typical RS-232 applications; in fact, the IBM ® PC serial port is implemented using only nine pins.For example, consider the case of a PC using this nine pin port to communicate with a peripheral device such as a modem. We see the following activity on each of the RS-232 lines as the computer and modem are activated and commu-nicate with each other as well as the remote modem at the other end of the phone line.Signal Ground (GND)The Signal Ground pin acts as a reference for all the other signals. This pin is simply maintained at a 0V level to serve as a level to which all other signals are referenced. Both the PC and the modem will have this line connected to their respective internal ground lines.元器件交易网Data Terminal Ready (DTR)This is the pin the computer uses to tell periph-eral devices that it is on–line and ready to communicate.Data Set Ready (DSR)Peripheral devices use this line to tell the com-puter that they are on–line and ready to commu-nicate. When the modem is turned on and has completed its self–test routine (assuming it does one), it will send a signal to the PC by asserting this line.Request To Send (RTS)The computer activates this line to notify the peripheral device that it is ready to send data. In this example, the computer notifies the modem that it is ready to send data to be transmitted by the modem.Clear To Send (CTS)This is the line on which the peripheral device tells the computer that it is ready to receive data from the computer. If the modem was not ready, i.e. it was performing a loop–back self–test, for example, it would not assert this line. Once the modem was ready to receive data from the PC, it would assert this line. When it receives the CTS signal from the modem, the PC knows that a data transmission path has been established between itself and the modem.Transmitted Data (TD or TX)This is the pin on which the computer sends the actual data signal to be transmitted, i.e. a posi-tive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (–3V to –15V) to represent a logic “1”. The PC would send the data on this line to be transmitted by the modem. Ring Indicator (RI)This line is used by the peripheral device to tell the computer that a remote device wants to start communicating. The modem would activate the RI line to tell the computer that the remote modem was calling, i.e. the phone is ringing. Data Carrier Detect (DCD)This line is used by the modem to tell the computer that it has completed a transmission path with the remote modem, and to expect to start receiving data at any time.Received Data (RD or RX)This is the pin on which the modem sends the computer the incoming data signal, i.e. a posi-tive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”.INTERFACE EXAMPLE – A PRINTER ON THE IBM PC SERIAL PORTThe RS-232 standard defines 22 serial interface signals. These signals consist of ground lines, timing, data, control and test signals, plus a set of signals rarely used for a second data channel. Many of these signal lines are not used in typical RS-232 applications; in fact, the IBM® PC serial port is implemented using only nine pins.For example, consider the case of a PC using this nine pin port to communicate with a peripheral device such as a printer. We see the following activity on each of the RS-232 lines as the com-puter and printer are activated and communicate. Signal Ground (GND)The Signal Ground pin acts as a reference for all the other signals. This pin is simply maintained at a 0V level to serve as a level to which all other signals are referenced. Both the PC and the printer will have this line connected to their respective internal ground lines.Data Terminal Ready (DTR)This is the pin the computer uses to tell peripheral devices that it is on–line and ready to communi-IBM Printer Port Interconnections元器件交易网cate. Once the computer is powered–up and ready, it will send out a signal on the DTR to inform the printer that it is powered–up and ready to go. The printer really doesn’t care, since it will simply print data as it is received. Accordingly, this pin is not needed at the printer.Data Set Ready (DSR)Peripheral devices use this line to tell the computer that they are on–line and ready to communicate. When the printer is turned on and has completed its self–test routine (assuming it does one), it will send a signal to the PC by asserting this line. Request To Send (RTS)The computer activates this line to notify the peripheral device that it is ready to send data. In this example, the computer notifies the printer that it is ready to send data to be printed by the printer. Clear To Send (CTS)This is the line on which the peripheral device tells the computer that it is ready to receive data from the computer. If the printer was not ready, i.e. it was out of paper, for example, it would not assert this line. Once the printer was ready to receive data from the PC, it would assert this line. When it receives the CTS signal from the printer, the PC knows that a data transmission path has been established between itself and the printer. Transmitted Data (TD or TX)This is the pin on which the computer sends the actual data signal representing the actual informa-tion to be printed, i.e. a positive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”. Ring Indicator (RI)This line is used by the peripheral device to tell the computer that a remote device wants to start com-municating. A modem would activate the RI line to tell the computer that a remote modem was calling, i.e. the phone is ringing. In the case of a printer, this line is unused.Data Carrier Detect (DCD)This line is used by a peripheral device to tell the computer to expect to start receiving data at any time. Since the printer would not be sending data to the PC in this case this line is not needed.Received Data (RD or RX)This is the pin on which the computer receives the incoming data signal, i.e. a positive voltage (+3V to +15V) to represent a logic “0”, and a negative voltage (-3V to -15V) to represent a logic “1”. Again, in this instance, since the printer will not be sending the PC any data, this line is not needed.元器件交易网ORDERING INFORMATIONModel

For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (A, B)...................................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO).....................-0.5V to (V CC +0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481/MAX483/MAX485 and MAX488–MAX491 have standard 12k ΩReceiver Input impedance.Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8_______________________________________________________________________________________Figure 2.

Figure 12 shows the dri-ver output waveform and its Fourier analysis of a 150kHz signal transmitted by a MAX481, MAX485,MAX490, MAX491, or MAX1487. High-frequency har-monics with large amplitudes are evident. Figure 13shows the same information displayed for a MAX483,MAX487, MAX488, or MAX489 transmitting under the same conditions. Figure 13’s high-frequency harmonics have much lower amplitudes, and the potential for EMI is significantly reduced.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers_______________________________________________________________________________________9_________________________________________________________________Test CircuitsFigure 4.

Receiver Enable and Disable Times (except MAX488and MAX490)Table 1. TransmittingTable 2. ReceivingLow-Power Shutdown Mode (MAX481/MAX483/MAX487)A low-power shutdown mode is initiated by bringing both RE high and DE low. The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.1µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.For the MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN ), t ZL(SHDN)) than from the operating mode (t ZH , t ZL ). (The parts are in operating mode if the –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

For line lengths greater than 4000 feet, see Figure 23.Figures 19 and 20 show the system differential voltage for the parts driving 4000 feet of 26AWG twisted-pair wire at 110kHz into 120Ωloads.Typical ApplicationsThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 transceivers are designed for bidirectional data communications on multipoint bus transmission lines.Figures 21 and 22 show typical network applications circuits. These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483 and MAX487–MAX489are more tolerant of imperfect termination.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________13DIV Y -V ZRO5V 0V1V0V -1V5V 0V2µs/divFigure 19.

DR240数据采集器英文介绍资料

Bulletin 04M01D01-00E Data Acquisition and Recording WindowsHybrid RecorderAdvanced instrumentation technology for cost-effective datalogging and data acquisition.Data Acquisition and Recording WINdows for now and the future./tm/... and subscribe to “Newswave,”our free e-mail newsletterHighly Advanced, Versatile, 250 mm Hybrid Recorderthat Meets Your Present and Future Needs A highly reliable, functional expert tool-idealfor data acquisition and recordingHighly Expandable and Cost Effective DR240 Expandable Model 45DR240 expandable model The DR240 expandable model consists of a main unit, subunits, input/output and com-munications modules. Connecting the main unit to multiple subunits with dedicated ca-bles of up to 500 m total length, you can easily configure a recording/data acquisi-tion environment ranging from 10 to 300channels. Another key feature is its ability to scan up to 300 channels every 500 ms.You can also install one subunit on the back of the main unit of the hybrid recorder.Subunits (DS400, DS600)A subunit acts as an interface for connect-ing input modules to the main unit of the DR240 expandable model. There are two types of subunits, the DS400 which permitsconnection of up to four input and output modules, and the DS600 which permits con-nection of up to six input and output mod-ules.Normally, when a subunit is connected, itwill be at a separate location from the main unit.(When a subunit DS600 is mounted on the back of a main unit, a dedicated cable is required between them.)Alarm output module This is a 4-channel or 10-channel output module which outputs contact alarm signals according to preset conditions. You can set four alarm levels per channel (choose from upper limit, lower limit, delta high limit, delta low limit, or rate-of-change). You can install alarm output modules on the subunits.Input ModuleThe input module is a 10-channel* small remote multiplexer that A/D-converts the measured signals as fast as every 500 ms.** The input signals include not only DC voltage and temper-ature, but also contact, power monitor, pulse, strain and DCA (mA) signals.*:Power monitor modules are 2- or 6-channel.**:If input modules of different measurement intervals are mixed, the resulting measurement interval is that of the longest intervalinput module.● Universal Input Module The universal input module permits mea-surement of DC voltages between 20 mV and 50 V, thermocouple inputs, RTD inputs,and contact signals in up to 500-ms inter-vals.Other cost-effective universal input modules are available that measure data from 20 or30 channels in 2-second intervals, and low-cost dedicated input modules that accept voltages and thermocouple outputs.● Strain Measurement ModuleThe strain measurement module measures static strain, and comes in two types.One corporates a 120 or 350Ω bridge resistor,the other is for connecting an external bridge box. One module enables data in 10 channelsto be measured, however, it requires two slotsworth of space.The minimum measurement in-terval (data update cycle) is 500 ms.● Pulse Input Module The pulse input module receives TTL or con-tact signals from a flow or tachometer, and counts and integrates the number of puls-es. The minimum measurement interval is0.5 second and the data update cycle is one second.● Power Monitor Module The power monitor module receives AC volt-age or current input signals and measures RMS values, active power, apparent pow-er, reactive power, frequency, power factor and phase angle.The minimum measurement interval (data update cycle) is 2 seconds.Main unit (DR242)The DR242 acquires data measured by the input modules installed on each subunit,records the data in real time and/or trans-fers it to a PC using a general-purpose com-munications interface, and also stores it in a memory device.You can connect a communication module,Ethernet, RS -232C, RS -422/485 or GP-IB,and also a DI/DO module to the main unit.An input module, on a subunit (DS600), can be installed on the back of the main unit. A highly reliable, functional expert tool-ideal for data acquisition and recording General-purpose communications module You can connect a Ethernet, RS-422A/RS-485, RS -232C, or GP-IB general-purpose communications module to the back panel of the main unit. All measured data is trans-ferred in real time via the installed commu-nications module.DI/DO module This module enables the DR240 hybrid re-corder to be controlled* from a remote lo-cation, and also outputs the chart end and recorder fail signals to your external annun-ciator.*Remote control functions:Start and stop recording Change chart speed Start message printing Start and stop memory sampling Control statistical calculation interval The DR242 expandable model incorporates the fail and chart end output as standard features.● Direct Current (mA) Module The shunt resistor (100 Ω) is pre-installed tomeasure the DCA signal.Extension module Using an extension module, you can sup-ply power directly from a subunit for each input module*1, mounted on an extension base unit. Also, connecting an extension module on a subunit allows connection of up to three input modules as well as three extension base units, over a distance of up to 30 m.*1 :10-ch universal input module or 10-ch DCV/TC/DI input module Dedicated cableDedicated cableGeneral-purpose cable Dedicated cableDV250-001 Cable adapter The DV250-001 cable extension adapter is used as a junction terminal for extending a dedicated cable that connects betweenDARWIN units or as an adapter for connecting the dedicatedcable to a different cable.Dedicated cable ➑Ethernet Module The Ethernet module enables you to achieve high-speed, multi-channel, remote data com-munication via Ethernet. The module supports all commands generally used for DARWIN and permits data access from a max-imum of four personal comput-ers (configured to do so with user-created software).Example of an extension module and base units with DS400subunit6This model has a simple building block architec-ture, and comes with I/O and communications modules installed on the back of the main unit.Structural SimplicityDR240 Stand-alone ModelSpecify 10, 20 or 30 input channels, and desired options, at the time of ordering.Simple integrated construction You can connect 10, 20 or 30 channels directly to the main unit.The DR240 stand-alone model, which comes with I /O modules already in-stalled, is a cost-effective general-pur-pose model.The external appearance, recorder function, memory and communications functions of this model are identical to those of the expandable model.

This application soft-ware makes your tasks of configuration and data acquistion quick and easy.DARWIN DAQ32 SoftwareDARWIN DAQ32Plus SoftwareThe data acquisition software 32PLus (DAQ32Plus) is the en-hanced software for common use with all the data gathering instruments in the DARWIN series. Like the standard DAQ32,this software includes hardware setup, simplified data logging,simplified data viewing, data conversion (Excel, Lotus 1-2-3or ASCII format), preference setting, system diagnosis, cali-bration, and tag number setting functions, all in one package.DAQ32Plus is far more powerful than DAQ32, however, in terms of the data monitoring and logging functions. It contains a number of additional functions not found in DAQ32. Additions include a display of up to 30 data groups each having a max-imum of 32 channels' worth of data per window (as compared with the DAQ32's display of up to 2 data groups each having a maximum of 10 channels' worth of data per window); dis-plays of various meters including level meters, analog meters and thermometers (not offered by DAQ32); alarm displays; as well as a DDE server, logger autostart, retry, password and tag setting function.Example of hardware setup displayThe data acquisition software 32 (DAQ32) is the standard soft-ware for common use with all the data gathering instruments in the DARWIN series. The software includes hardware setup,simplified data logging, simplified data viewing, data conver-sion (Excel, Lotus 1-2-3 or ASCII format), preference setting,system diagnosis and calibration functions, all in one pack-age. All models of the DA100 data acquisition unit and DC100data collector come standard with this software. For each model of the DR130, DR230 and DR240 hybrid data record-ers, you can specify whether software is necessary or unnec-essary when ordering. When you specify software as "neces-sary," DAQ32 software comes standard with the model.Example of date logging displayExample of date viewing display10The DR240 provides many economic benefits forthe user, such as reduced wiring for remote mea-surement, space saving due to compact design,and optimized signal conversion costs due to theavailability of a large variety of input modules.Max. 500 ms/300 channel highspeed measurement (expand-able model)Parallel processing of data is used bythe dedicated A/D converter inside eachinput module. 1 Mbps high speed datatransfer is accomplished between themain unit and each subunit. Further-more, the use of a distributed multi-CPUcontrol method for the overall systemachieves high speed measurement ofdata from 300 channels over an intervalof 500 ms. The DR240 has a time axisresolution four times that of the previ-ous model (DA2500E), achieving bettertime synchronization between channels.Space saving due to compactdesignThe depth of the main unit of the DR240hybrid recorder has been greatly re-duced: it is about 60%* of previousmodels in the case of the 60-channelmodel, and about 80%** in the case ofthe 30-channel general-purpose mod-el. Also, the use of high breakdown volt-age solid state relays and a planar trans-former developed by YOKOGAWA hasenabled the volume of the 60-point in-put remote measurement section to bereduced to 1/5*** of that of previousmodels, resulting in a highly compactunit. The mass of the unit has also beenreduced to about 1/2*. This makes formore efficient use of control room or lab-oratory space and reduces toal costs.*Compared to YOKOGAWA's HR2500E, in-cluding the input measurement section**Compared to YOKOGAWA's HR2400, in-cluding the input measurement sectionIn addition, it provides superb environmental rug-gedness, and onboard computation and memoryfunctions, enabling it to be used for a wide rangeof applications.Application Versatilityules are installedDA2500E remote scanner11Computing functions The main unit of the DR240 with option-al MATH feature can perform the four arithmetic operations, integration of measured data, and computations such as detection of maximum and minimum values, in realtime. Even without the optional feature, the DR240 can com-pute linear scaling, difference and mov-ing average. The results of such com-putations are transferred with the mea-sured data to a PC, thus reducing sys-tem requirements on the PC and also resulting in more efficient analytical pro-cessing.The main computing functions are as follows. (The shortest computation peri-od differs depending on the kind of com-putation.)Standard computing functions Linear scaling, moving average, differ-ential calculation, pulse integration (when a pulse input module is recognized)Optional functions The four arithmetic operations, logic operations, related operations, calcula-tion of absolute and relative values, and statistical calculations (maximum, mini-mum, mean, and integrated values for fixed intervals)Report function (/M3)You can calculate the maximum, mini-mum, average values, and integrated value of the measured results, and print hourly, daily and monthly reports. The calculated values are also recorded in the report results.Memory function You can select a floppy disk function with 512 kB SRAM capability for stor-age of information on a removable me-dia. You can save several configura-tion setups and in addition store themeasured data before and after analarm, and also calculated values.You can record the memorized data on DR240 chart, transfer it off-line to a PC,or analyze it or make it into a report us-ing commercially available spreadsheet software.●You can save the measured data in the following cases:•By manual command or when a com-munications command is input •When an alarm is detected •When the end of the chart is reached ●The save modes are as follows:•Single: Data of the specified length is sampled once only.•Repeat: Data of the specified length is sampled exactly the number of times specified in advance.*When measured values are saved to a flop-py disk, they are first stored in the buffer memory (512 kB DRAM).By using the DR240 in combination with the optional DI/DO module or alarm function, you can easily perform batch processing.● Moving average functionThis function renews the measured val-ue while calculating the moving average,is effectively monitoring the trend of a varying input signal over a long period.It can also be used as a digital filter when noise components are present on the input signal. You can set the number of moving average scans by selecting avalue between 2 and 64.12High breakdown voltage solidstate relay (SSR)Developed by YOKOGAWA, the SSRswitches the inputs when performingmulti-channel measurement. A semi-conductor device takes the place of thecontacts and drive part of a mechani-cal relay, thus overcoming the problemof defective measurement caused byfaulty or worn contacts of the mechani-cal type relay. YOKOGAWA's solid staterelay has a high breakdown voltage(1500 VDC), enhancing safety in thefield. Also, its low leakage current (1nA) enables the very low level voltagesignals from a thermocouple to be mea-sured with high accuracy.YOKOGAWA currently uses this SSR inits hybrid recorders and the advancedµR series of industrial recorders. Over800 thousand channels of this technol-ogy have performed successfully in var-ious field and laboratory applications,thus verifying the reliability of the relaydevice.A new surface-mounted version of thishighly reliable SSR is used in the DAR-WIN family.This permits a high degree of miniatur-ization, low power consumption, longdevice life and quiet operation.Increased ReliabilityYOKOGAWA has Continually Improved its Measurement Technology for Your BenefitThe history of YOKOGAWA in strip chart recordinginstruments can be summarized as the provisionof the world's most reliable and readable record-ers, with unmatched performance, over the last fif-teen years. In 1981, YOKOGAWA developed theModel 4088 hybrid recorder which was the first dotprinting type recorder in the world to contain a mi-croprocessor. Since then, we have continued tomake many technical breakthroughs, including thenon-contact ultrasonic position detector, and highbreakdown voltage (HBV) solid state relay, bring-ing multipoint recording closer to perfection.This commitment to you is also evident in theDR240 hybrid recorder, which uses YOKOGAWA'sadvanced technologies to help you achieve higherreliability and compactness, and improved PC-com-patibility.Planar transformerA planar transformer is a revolutionaryintegrated transformer which takes theplace of the conventional wire-woundtransformer, the most antiquated of allelectronic components. This small, thintransformer consists of multi-layer pre-cision thin film coils, enhancing insula-tion, and also reducing heat and noiseemission. This concept design meansthat the power supply unit occupies just1/2 to 1/4 of the volume of conventionalunits.All of the transformers in the main unit,subunits and input and output modulesof the DR240 are planar transformers.This is an important factor in achievingthe large degree of miniaturization andweight reduction of the DR240.Adoption of ASICsThe DR240 uses ASI Cs (ApplicationSpecific Integrated Circuit) which weredeveloped with more than 40 years ofdata acquisition know-how accumulat-ed by YOKOGAWA. Moreover, a highdegree of integration has been attainedby gate arrays, used around the A/Dconverter, communication interface, re-cording and display control circuits. Asa result of this high degree of integra-tion, the DR240 has become smaller andlighter, and power consumption andheat generation reduced, improving thereliability of the overall system.Advanced carriage driveThe carriage drive section of the dotprinter head employs a screw shaftwhich is unique for a strip chart record-er. The drive belt and wire cable havebeen removed, resulting in increasedreliability.Integration of the design, manu-facture and quality evaluationsystemRoutine installation work is automated,preventing careless mistakes during theproduction process from assemblythrough inspection. The result is a highgrade, highly reliable product.We also use precision test equipmenton the production line to further increasereliability.Supported standardsCSAULCEC-TickObtained CSA22.2 No.1010.1,Installation category (Overvoltagecategory): II, Degree of pollution: 2Obtained UL3111-1 (CSA NRTL/C)EMCdirectiveLow voltagedirectiveAS/NZS 2064 Class A Group 1EN61326EN61000-3-2EN61000-3-3EN55011 Class A Group 1EN61010-1Measurement category: II,Degree of pollution: 213SpecificationsHz) and 100 ms (10 Hz)Minimum measurement interval when the 100-ms integration mode becomes:DR241:30 channels; 6 seconds●Number of Recording Points300 points maximum (stand-alone model: 30 points + AC 6 points)●Recording PaperEffective recording width :250 mm (for analog trend measurement)●Analog recording color (You can specify a color for each channel.)Purple, red, green, blue, brown, black, navy blue, yellow-green, red-purple,orange●Analog Recording Interval FIX:Recording takes place at the specified measurementinterval between 2 and 60 seconds (not all measured values are sampled for analog recording in case of the 0.5- and 1-second measurement intervals)AUTO:Linked to recording paper feed speed ●Recording Paper Feed Paper feed speed: 1 to 1,500 mm/hour Display Section ●Display Section Display:VFD display (5 x 7 dot matrix, 3 lines)Number of characters:22 characters (large/1 line), 40 characters (2 lines)Memory Function Section ●Memory Media3.5-inch floppy disk drive with 512 kB SRAM buffer memory ●Data Capacity10 data/ch to 50 kdata/ch(Total data memory should be less than total memory length.)●Applicable dataSetting values, measurement values and computed values except report calculating values ●Memory Mode BinaryCan be converted to ASCII (CSV) format for copying buffer memory data to floppy disk ●Sample RateSynchronized with the measurement interval of the recorder unit, or synchronized with event.Alarms●Number of SettingsUp to four settings can be made for each channel.●Kinds of AlarmsUpper/lower limit, difference upper/lower limit, upper/lower limit of percentage change, upper or lower limit only for the results of computation Percentage change alarm time interval: 1 to 15 scans ●Number of Alarm Output Points DR241:12 maximum (alarm option: 10; DI/DO option: 2)DR242:300 in total Standard Computation Functions ●Kinds of ComputationDifference between arbitrarily selected channels, linear scaling, moving average,pulse integrationScalable range:DC voltage, thermocouple, RTD, contact Scaling range:–30,000 to +30,000Moving average: 2 to 64 scans Pulse integration:Effective when a pulse input module is recognized(up to 60 channels)Fail, Chart End Output(DR expandable model.
