Terminal Functions
TERMINAL NAME AIN0 – AIN10 NO. 1 – 9, 11, 12 15 I/O I DESCRIPTION Analog input. These 11 analog-signal inputs are internally multiplexed. The driving source impedance should be less than or equal to 50 Ω for 4.1-MHz I/O CLOCK operation and capable of slewing the analog input voltage into a capacitance of 60 pF. Chip select. A high-to-low transition on CS resets the internal counters and controls and enables DATA OUT, DATA INPUT, and I/O CLOCK. A low-to-high transition disables DATA INPUT and I/O CLOCK within a setup time. Serial-data input. A 4-bit serial address selects the desired analog input or test voltage to be converted. The serial data is presented with the MSB first and is shifted in on the first four rising edges of I/O CLOCK. After the four address bits are read into the address register, I/O CLOCK clocks the remaining bits in order. Serial data output. This is the 3-state serial output for the A/D conversion result. DATA OUT is in the high-impedance state when CS is high and active when CS is low. With a valid CS, DATA OUT is removed from the high-impedance state and is driven to the logic level corresponding to the MSB/LSB value of the previous conversion result. The next falling edge of I/O CLOCK drives DATA OUT to the logic level corresponding to the next MSB / LSB, and the remaining bits are shifted out in order. End of conversion. EOC goes from a high to a low logic level after the falling edge of the last I/O CLOCK and remains low until the conversion is complete and data are ready for transfer. Ground. This is the ground return terminal for the internal circuitry. Unless otherwise noted, all voltage measurements are with respect to GND. I Input /output clock. I/O CLOCK receives the serial input and performs the following four functions: 1. It clocks the eight input data bits into the input data register on the first eight rising edges of I/O CLOCK with the multiplexer address available after the fourth rising edge. 2. On the fourth falling edge of I/O CLOCK, the analog input voltage on the selected multiplexer input begins charging the capacitor array and continues to do so until the last falling edge of I/O CLOCK. 3. It shifts the 11 remaining bits of the previous conversion data out on DATA OUT. Data changes on the falling edge of I/O CLOCK. 4. It transfers control of the conversion to the internal state controller on the falling edge of the last I/O CLOCK. Reference +. The upper reference voltage value (nominally VCC) is applied to REF+. The maximum input voltage range is determined by the difference between the voltage applied to this terminal and the voltage applied to the REF – terminal. Reference –. The lower reference voltage value (nominally ground) is applied to REF –. Positive supply voltage.

ADM485FUNCTIONAL BLOCK DIAGRAMCC 00078-001FEATURESMeets EIA RS-485 standard 5 Mbps data rateSingle 5 V supply–7 V to +12 V bus common-mode range High speed, low power BiCMOS Thermal shutdown protection Short-circuit protectionDriver propagation delay: 10 ns typical Receiver propagation delay: 15 ns typical High-Z outputs with power off Superior upgrade for LTC485APPLICATIONSLow power RS-485 systems DTE/DCE interface Packet switchingLocal area networks (LNAs) Data concentration Data multiplexersIntegrated services digital network (ISDN)GENERAL DESCRIPTIONThe ADM485 is a differential line transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission and complies with EIA standards RS-485 and RS-422. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver can be enabled independently. When disabled, the outputs are three-stated.The ADM485 operates from a single 5 V power supply. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. If during fault conditions, a significant temperature increase is detected in the internal driver circuitry, this feature forces the driver output into a high impedance state.Up to 32 transceivers can be connected simultaneously on a bus, but only one driver should be enabled at any time. It is important, therefore, that the remaining disabled drivers do not load the bus. To ensure this, the ADM485 driver features high output impedance when disabled and when powered down, which minimizes the loading effect when the transceiver is not being used. The high impedance driver output is maintained over the common-mode voltage range of −7 V to +12 V .Figure 1.The receiver contains a fail-safe feature that results in a logic high output state if the inputs are unconnected (floating). The ADM485 is fabricated on BiCMOS, an advanced mixed technology process combining low power CMOS with fast switching bipolar technology. All inputs and outputs contain protection against ESD; all driver outputs feature high source and sink current capability. An epitaxial layer is used to guard against latch-up.The ADM485 features extremely fast switching speeds. Minimal driver propagation delays permit transmission at data rates up to 5 Mbps while low skew minimizes EMI interference. The part is fully specified over the commercial and industrial temperature range and is available in 8-lead PDIP , 8-lead SOIC, and small footprint, 8-lead MSOP packages.ADM485Rev.

恒流工作
M5839 的恒压/恒流特征曲线如图 1 所示。M5839 被设计应用于工作在非连续模式下的反激式系统中。
在正常工作时，当 INV 电压低于内部 2.0V 的基准电压好时，系统工作在恒流模式，否则系统工作在恒压
模式。当次级输出电流达到了系统设定的最大电流时，系统就进入恒流模式，并且会引起输出电压的下降。
M5839 在 CS 端设计了一个约为 540ns 的前沿消隐时间用来防止在开关导通时刻错误的过流保护被 触发。因此，不需要在 CS 端在增加额外的 RC 滤波电路。采样电流的输入信号 CS 和误差放大器的输出 COM 共同决定开关的占空比，稳定输出. EMI 特性的改善
为了改善 M5839 系统的 EMI 特性，芯片内部采用了两种方式。其中一种方式是采用频率抖动，即在 M5839 正常工作频率的基础上叠加一个微小的扰动。也就是说，内部振荡器的频率被调制用来分散谐波干 扰能量，分散的能量能够最小化 EMI 带宽。另一种方式是软驱动，即逐渐打开功率 MOSFET。当提供给功 率 MOSFET 的栅驱动太强时， EMI 特性会变差；当提供给功率 MOSFET 的栅驱动太弱时，开关损耗又会 加大，因此需要在 EMI 特性和开关损耗之间寻求折衷来提供合适的栅驱动。M5839 采用了软驱动和图腾柱 输出结构，既获得了很好的 EMI 特性，又降低了开关损耗。频率抖动和软驱动的综合应用使系统的 EMI 特 性获得了很大的改善。 保护控制

50V64-743 Integrated Furnace Control 安装说明书
If in doubt about whether your wiring is millivolt, line, or low volt-age, have it inspected by a qualified heating and air conditioning contractor or licensed electrician.Do not exceed the specification ratings.All wiring must conform to local and national electrical codes and ordinances.This control is a precision instrument, and should be handled carefully. Rough handling or distorting components could cause the control to malfunction.FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULL Y BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.CONTENTSDescription .............................................................1Precautions ............................................................1Specifications .........................................................2Operation ................................................................2Installation ..............................................................5 Mounting & WiringThe 50V64-743 is a two-stage automatic gas interrupted ignition control employing a microprocessor to continually monitor, analyze, and control the proper operation of the gas burner and inducer, and provide signal for proper operation of variable fan speed timing.Signals interpreted during continual surveillance of the two-stage thermostat and flame sensing element initiate automatic ignition of the burner, sensing of the flame, and system shutoff during normal operation.The control incorporates system fault analysis for quick gas flow shutoff, coupled with automatic ignition retry upon sensing a fault correction.PART NO. 37-7565A1503 DESCRIPTIONPRECAUTIONS2SPECIFICATIONSOPERATIONOPTION SWITCHESSwitches on the 50V64-743 control are used to control functions of the circulator blower. Switches labeled SW3 and SW4 control the circulator blower speed. Switch labeled SW2 controls the heat delay-to-fan-off period.

Please set the switches for the delay period according to the chart above.If W1 and W2 are tied together, the time delay of second stage is based on the switch settings of SW1, per the following table.HEAT MODEIn a typical system, a call for first stage heat is initiated by closing the W1 thermostat contacts. The Humidifier output is energized and the inducer blower is enabled at low speed. The control waits for the stage 1 pressure switch to close. When the pressure switch closes the silicon nitride ignitor is powered. This control has an adaptive algorithm that reduces the ignitor temperature to slightly greater than the minimum temperature required to ignite gas in each particular application. The con-trol measures the line voltage and determines an initial ignitor temperature setting based on the measurement. After each successful ignition, the control lowers the ignitor temperature slightly for the next ignition attempt. The control continues to lower the ignitor temperature until ignition does not occur, and the control goes into retry mode. For the second attempt to ignite gas within the same call for heat, the control increases the ignitor temperature to the value it was on the previous successful ignition. After ignition is successful, the control sets the ignition temperature at this value. The control is constantly making adjustments to the ignitor modulation routine to com-pensate for changes in the line voltage. The control will relearn after power interruptions.The Silicon Nitride ignitor manufactured by White-Rodgers must be used. These ignitors are specially designed to operate with the adaptive ignition routine used by the control to ensure the most efficient ignitor temperature.At the end of the ignitor warm-up time, the first stage of the two-stage manifold gas valve is energized (low fire). Flame must be detected within 5 seconds. If flame is detected, the 45 second delay-to-fan-on period begins. After the delay-to-fan-on period ends, the circulator enable, (pin 15 on the 16-pin connector is the “E” output to the circulator) and air cleaner are energized.A call for second stage heat (W1 and W2) after a call for first stage heat will activate a 30-second 2nd stage delay. Following the 30-second delay, the inducer motor is driven at high speed. The control checks the 2nd stage pressure switch. When the pressure switch closes, the 2nd stage gas valve turns on and the circulator is enabled at high speed (“E” remains energized any time the circulator is on).When the second stage of the thermostat is satisfied, the inducer motor is reduced to low speed, and the 2nd stage gas valve and high circulator speed are de-energized.When the first stage of the thermostat is satisfied, the gas valve is de-energized and the heat delay-to-fan-off timing begins. The inducer will postpurge for an additional 5 seconds. When this time is expired, the inducer and humidifier will de-energize. Upon completion of the heat delay-to-fan-off period, the circulator and air cleaner are de-energized.If flame is not detected during the trial-for-ignition period, the gas valve is de-energized, the ignitor is turned off, and the control goes into the “retry” sequence.The “retry” sequence starts with a 60-second interpurge, en-abling the inducer at low speed for 60 seconds following an unsuccessful ignition attempt (flame not detected). After this wait, the ignition sequence is restarted. If this ignition attempt is unsuccessful, one more retry will be made before the control goes into system lockout.If flame is detected, then lost, the control will repeat the initial ig-nition sequence for a total of ten “recycles”. After ten unsuccessful attempts to sustain flame, the control will go into system lockout.During burner operation, a momentary loss of power of 250 milliseconds or longer will de-energize the main gas valve. When power is restored, the gas valve will remain de-energized and a restart of the ignition sequence will begin immediately.A momentary loss of gas supply, flame blowout, or a shorted or open condition in the flame probe circuit will be sensed within 2 seconds. The gas valve will de-energize and the control will restart the ignition sequence. Recycles will begin and the burner will operate normally if the gas supply returns, or the fault con-dition is corrected, before the last ignition attempt. Otherwise, the control will go into system lockout.If the control has gone into system lockout, it may be possible to reset the control by a momentary power interruption of five seconds or longer. Refer to PRECAUTIONARY, SYSTEM LOCKOUT, AND DIAGNOSTIC FEATURES.COOL MODEIn a typical system, a call for cool is initiated by closing the thermostat contacts. This energizes the compressor, circulator “E” output and air cleaner. After the thermostat is satisfied, the compressor is de-energized and the optional cool mode delay-to-fan-off period begins. After the optional delay-to-fan-off period ends, the circulator “E” output and air cleaner are de-energized.MANUAL FAN ON MODEIf the thermostat fan switch is moved to the ON position, the circulator “E” output and air cleaner are energized. When the fan switch is returned to the AUTO position, the circulator “E” output and air cleaner are de-energized. PRECAUTIONARY, SYSTEM LOCK-OUT, AND DIAGNOSTIC FEATURES PRECAUTIONARY FEATURESThe following precautionary features are built into the control.1. If the high temperature limit or flame rollout sensor openat any time, the gas valve is de-energized.2. During a call for heat cycle, if flame is sensed at any timewhen the gas valve is de-energized, the circulation “E” output and inducer fan are energized at low speed in conjunction with system lockout.3. If the high limit (and/or auxiliary limit) switch(es) open atany time during a call for heat, the circulator blower and inducer fan are energized at low speed.SYSTEM LOCKOUT FEATURESWhen system lockout occurs, the gas valve is de-energized, the circulator “E” output and the inducer blower are energized at low speed. The diagnostic indicator light will flash to indicate system status. (System lockout will never override the precautionary features described above.)To reset the control after system lockout, do one of the following:1. Interrupt the call for heat at the thermostat for at least onesecond and less than twenty seconds (if flame is sensedOPERATION34MOUNTING AND WIRINGINSTALLATIONAll wiring should be installed according to local and national electrical codes and ordinances.The 50V64 control may be mounted on any convenient surface using the four standoffs provided.The control must be secured to an area that will experience a minimum of vibration and remain below the maximum ambient temperature rating of 175°F . T he control is approved for minimum ambient temperatures of -40°F .Any orientation is acceptable.Refer to the wiring diagram and wiring table when connecting the 50V64 control to other components of the system.UL approved, 105°C rated 18 gauge min., stranded,²/64" thick insulation wire is recommended for all low voltage safety circuit connections. Refer to 50V64 control specification sheet for recommended terminals to mate with those on the control.UL approved, 105°C rated 16 gauge min., stranded, 4/64" thick insulation wire is recommended for all line voltage connections. Refer to 50V64 control specification sheet for recommended terminals to mate with those on the control.Following installation or replacement, follow appliance manufacturer’s recommended installation or service instructions to insure proper operation.5 flashes, then pause Flame sense when no flame should be present6 flashes, then pause Line reverse polarity or ignitor circuit error7 flashes, then pause Gas valve circuit error 8 flashes, then pause Weak flame9 flashes, then pauseOpen inducer limit errorThe Green and Red LED's will also flash once for 1 second atpower-up.FAULT CODE RETRIEVAL Two seconds after the power ON, the control shall flash the last four error codes that have occurred over the last 14 days on the red LED. The control will flash the newest error first and the oldest error last with a two-second pause between flash codes. Solid LED error codes will not be displayed. The green ST A TUS LED shall remain ON while the red LED flashes the error codes.The last four fault codes can be erased from memory by pow-ering up with G energized and then toggling W1 three times within eight seconds. W1 must be toggled after the power ON reset for approximately one second each time. The control will acknowledge by turning on the red LED and green ST A TUS LED for two seconds.with the gas valve de-energized, interrupting the call for heat at the thermostat will not reset the control).2. Interrupt the 24 VAC power at the control for at least fiveseconds. Y ou may also need to reset the flame rollout sensor switch.3.After one hour in lockout, the control will automatically reset itself.DIAGNOSTIC FEATURESThe control continuously monitors its own operation and the operation of the system. If a failure occurs, the red LED on thecontrol will flash a failure code. If the Red and Green "status"LED's are on solid, the 5 amp replaceable fuse is bad. If the fuse is good or the Red LED is on by itself, the entire control should be replaced, as the control is not field-repairable.If the sensed failure is in the system (external to the control), the red LED will flash in the following flash-pause sequences to indicate failure status (each flash will last approximately 0.25 seconds, and each pause will last approximately 2 seconds).2 flashes, then pause Retries or recycles exceeded 3 flashes, then pause Inducer or pressure switch error4 flashes, then pause Open limit or rollout switchOPERATION550V64 TERMINALTYPE SYSTEM COMPONENT CONNECTIONLINE Input voltage (120 VAC) HOT SIDE XFMR-H spade terminal*24 VAC transformer line voltage neutral side Input voltage (120 VAC) neutral sidespade terminal*24 VAC CommonLow heat speed select, output to circulator blower 24 VAC CommonDelay tap, output to circulator Cool tap, output to circulator YLO, output to circulatorAdjust tap, output to circulator 24 VAC Common O, output to circulatorHumidistat, output to circulator Heat tap, output to circulator 24 VACW2, output to circluator Y, output to circulator G, output to circulator G reen CFM indicator spade terminal*Circulator blower neutral sideCIR-H CIR-N XFMR-N FPHUM - N EAC - N EAC HUM LINE-N spade terminal*24 VAC transformer line voltage hot side spade terminal*spade terminal*spade terminal*spade terminal*spade terminal*spade terminal*spade terminal*4-pin connector 16-pin connectorTYPICAL SYSTEM WIRING TABLECirculator blower hot sideHumidifier hot sideElectronic Air Cleaner hot side Humidifier neutral sideElectronic Air Cleaner neutral side Flame probe**** maximum recommended flame probe wire length is 36 inches.IND 01 (1)IND 02 (2)IND 03 (3)GRND (4)Inducer 01Inducer 02Inducer 03Inducer ground2-pin connector IGN-H IGN-N Ignitor output Ignitor common * Spade terminals are 0.25" x 0.032"W1W2G R B/C YLO Y BK OMVH (3)MV COM (8)HLI (2)HLO (9)TR (11)MV (4)TH (7)GND (5)PS2 (6)PS0 (1)IL1 (10)PS1 (12)E11-1E11-2E11-3E11-4E11-5E11-6E11-7E11-8E11-9E11-10E11-11E11-12E11-13E11-14E11-15E11-16First stage call for heat Second stage call for heat Input for fan operation24 VAC transformer (HIGH side)24 VAC transformer (LOW side)First stage call for cool Second stage call for cool Humidistat enable H/P or cooling modeGas valve second stage Gas valve ground High limit input High limit output24 VAC transformer (low voltage COMMON side)Gas valve first stage24 VAC transformer (low voltage HIGH side)MUST BE RELIABLY GROUNDED TO CHASSIS 2nd stage pressure switch Pressure switch output Inducer limit input1st stage pressure switch12-pin connector9-screw terminal block120 VACHOT NEUTRAL TYPICAL SYSTEM WIRING DIAGRAM7White-Rodgers is a business of Emerson Electric Co.The Emerson logo is a trademark and service mark of Emerson Electric Co. 。

DRSP-I, DRSP-I-DC4-20 mA Isolated Signal SplittersM-5244/1114DescriptionThe DRSP-I series accepts a 4-20 mA current input and provides two optically isolated 4-20 mA current outputs that are linearly related to the input. Typical applications include isolation, output splitting, output device separa-tion, and redundancy (i.e. to prevent failure of the entire loop if one device fails), or a combination of these.Full 4-way isolation makes this module useful for ground loop elimination, common mode signal rejec-tion, or noise pickup reduction.Sink/Source I/OStandard is a 15 VDC loop excitation supply for the input and a 20 VDC loop excitation supply for each output. These power supplies can be selectively wired for sinking or sourcing allowing use with any combination of powered or unpowered milliamp I/O devices.I/O Status LEDsA green input L ED and two red output L EDs vary in intensity with changes in the process input and output signals. These provide a quick visual picture of your process loop at all times.Output TestAn output test button provides a fixed output (inde-pendent of the input) when held depressed. The test output level is potentiometer adjustable from 0 to 100% of output span.Terminals are provided to operate the test functions remotely for each channel. This also allows use as a remote manual override to provide a temporary fixed output.Input Range 4-20 mADC Input Impedance 50 Ω typicalVoltage Burden1.25 VDC max. at 20 mA current inputInput Loop Power Supply 15 VDC ±10%, regulated, 25 mADCMay be selectively wired for sinking or sourcing mA input LED IndicatorsVariable brightness LEDs indicate I/O loop level and status One for input, one for each output Output Range Channel 1: 4-20 mADC Channel 2: 4-20 mADC Output LinearityBetter than ±0.1% of spanOutput Zero and SpanMulti-turn zero and span potentiometers for each output chan-nel to compensate for load and lead variations ±15% of span adjustment range typicalOutput Loop Power Supplies One for each output channel20 VDC nominal, regulated, 25 mADCMay be selectively wired for sinking or sourcing mA output Output Ripple and Noise Less than 10 mV RMSOutput Functional TestFront buttons set each output to test level when pressed Each test level potentiometer adjustable 0-100% of spanTerminals provided for remote switching of each output to test levelResponse Time 70 milliseconds typical Common Mode Rejection 120 dB minimumIsolationFull 4-way isolation: input 1, output 1, output 2, power 1200 V RMS minimumAmbient Temperature Range and Stability –10°C to +60°C operating ambientBetter than ±0.04% of span per °C stabilityPower85-265 VAC, 50/60 Hz or 60-300 VDC, 6 W maximumDC version: 9-30 VDC or 10-32 VAC 50/60 Hz, 6 W maximum HousingIP 40, mounts to standard 35 mm DIN rail ConnectorsEight 4-terminal removable connectors 14 AWG max wire size Dimensions1.78" W x 4.62" H x 4.81"D45 mm W x 117 mm H x 122 mm D Height includes connectorse-mail:**************For latest product manuals:User’s Gui d eShop online atOutput LEDs: Variable brightness red LED indicates output level for each channelTest Cal.: Output test level adjustmentTest: Push to test output.

Typical when using a passive or unpowered transmitter or sensor.Electrical ConnectionsWARNING! All wiring must be performed by a qualified electri-cian or instrumentation engineer. See wiring diagrams.Avoid shock hazards! Turn signal input, output, and power off before connecting or disconnecting wiring.The DRSP-I is factory configured for one 4-20 mA input and two 4-20 mA outputs as indicated on the serial number label.To maintain full isolation, avoid combining power supplies in common with inputs, outputs, or unit power.The power supplies are fuse protected and the unit may be returned for fuse replacement.Signal Input TerminalsPolarity must be observed when connecting the signal inputs. The DRSP-I may be wired for a sinking or sourcing input.Determine if your input device provides power to the current loop or if the loop must be powered by the DRSP-I. Typical voltage may be 9-24 VDC at your device’s terminals if it provides power to the loop.Signal Output TerminalsPolarity must be observed when connecting the signal outputs.The two DRSP-I output channels may be individually wired for a sinking or sourcing output as needed.For each channel determine if your output device provides power to the current loop or if the loop must be powered by the DRSP-I. Typical voltage may be 9-24 VDC at your device’s terminals if it provides power to the loop.The wiring diagram illustrates typical wiring examples. Each channel may be wired as needed.If the output does not function, check wiring and polarity for both inputs and outputs.Module Power TerminalsCheck white model/serial number label for module operating voltage to make sure it matches available power.Connect power last. When using DC power, either polarity is acceptable, but for consistency with similar products, positive (+) can be wired to terminal 13 and negative (–) can be wiredto terminal 16.External Contacts For Test FunctionClosing the contact provides the same function as pressing the Test button for each channel. May be used as a manualoverride.Current Sinking OutputsTypical of some PLCs that have current sourcing inputs.Current Sinking Outputs with Separate Power SuppliesTypical of a system using loop powered displays with external loop supplies.Current Sourcing OutputsDRSP-I provides power to each loop. Typical of a system or PLC using current sinking inputs.Current Sinking InputTypical of a system using a transmitter that is externally pow-ered and provides power to the loop.Current Sinking Input with Separate Power SupplyTypical of a system using a passive transmitter that uses a loop power supply to power to the loop.Module PowerDRSP-I: 685-265 VAC, 50/60 Hz or 60-300 VDC DRSP-I-DC: 9-30 VDC or 10-32 VAC 50/60 Hz2324To maintain full isolation, avoid combining power supplies in common with inputs, outputs, or unit power.DC to DC Isolated Signal SplitterCalibrationFront-mounted Zero and Span potentiometers for each channel can be used to compensate for load and lead variations.1. Apply power to the module and allow a minimum 30 minute warm up time.2. Using an accurate calibration source, provide an input to the module equal to the minimum input required for the applica-tion.3. Using an accurate measurement device for the output, adjust the Zero potentiometer for the exact minimum output desired. The Zero control should only be adjusted when the input signal is at its minimum. This will produce the cor-responding minimum output signal. The Zero control will provide adjustment for the 4 mA or low end of the signal.4. Set the input at maximum, and then adjust the Span pot for the exact maximum output desired. The Span control should only be adjusted when the input signal is at its maximum. This will produce the corresponding maximum output signal. The Span control will provide adjustment for the 20 mA or high end of the signal.5. Repeat adjustments for maximum accuracy.6. Repeat adjustments for second channel.Output Test FunctionWhen the Test button is depressed it will drive the output with a known good signal that can be used as a diagnostic aid during initial start-up or troubleshooting. When released, the output will return to normal.The Test Cal. potentiometer is factory set to approximately 50% output. It can be adjusted to set the test output from 0 to 100% of the output span.Press and hold the Test button and adjust the Test Cal. potenti-ometer for the desired output level.The output test function for each channel may be externally wired for remote test operation or a manual override. See wir-ing diagram.MountingThe housing clips to a standard 35 mm DIN rail. The housing is IP40 rated and should be mounted inside a panel or enclosure. See illustration below.Avoid shock hazards! Turn signal input, output, and power off before installing or removing module.1. Tilt front of module downward and position the lower mounts and spring clips against the bottom edge of DIN rail.2. Push front of module upward until upper mount snaps into place.Removal1. Push up on bottom back of module.2. Tilt front of module downward to release upper mount from top edge of DIN rail.3.The module can now be removed from the DIN rail.Upper Mount OperationThe DRSP-I accepts a 4-20 mA current input and provides two optically isolated 4-20 mA current outputs that are linearly related to the input.The green input L ED provides a visual indication that a signal is being sensed by the input circuitry of the module. It also indicates the input signal strength by changing in intensity as the process changes from minimum to maximum.If the LED fails to illuminate, or fails to change in intensity as the process changes, check the module power or signal input wiring.The two red output L EDs provide a visual indication that the output signals are functioning. They become brighter as the input and each corresponding output change from minimum to maximum.The red L ED will only light if the output loop current path is complete. Failure to illuminate or a failure to change in intensity as the process changes may indicate a problem with the module power or signal output wiring.Note that it may be difficult to see the LEDs under bright lighting conditions and low I/O levels.It is the policy of OMEGA to comply with all worldwide safety and EMC/EMI regulations that apply.
