Installation Instructions POINTBlock ac 8 Input/8 Relay Output Module(Cat. No. 1734D-IA8XOW8, -IA8XOW8S) ArrayThis 1734D input/output module is a DIN-rail mounted device with an integrated DeviceNet communication interface, 8 ac inputs and 8 relay outputs, removable terminations, and a PointBus expansion port. The expansion port allows you to add up to a maximum of 12 additional POINT I/O modules.The module includes a non-isolated DeviceNet communication interface. The 24V dc from the DeviceNet connection powers a non-isolated dc/dc converter that generates +5V dc which powers the POINTBlock electronics and connects to the PointBus port to power the expansion I/O electronics.The 1734-IA8XOW8 uses cage-clamp terminations, and the1734-IA8XOW8S uses spring-clamp terminations.2 POINTBlock ac 8 Input/8 Relay Output ModuleWhatever field power you supply is connected to the internal field-power bus. For example, if 120V ac is applied to the power connections, there will be 120V ac applied to the modules through the internal field-power bus.POINT I/O modules to the right of the module will also have that internal power bus voltage applied, unless you use a 1734-FPD to interrupt and change the field power-bus voltage.ConnectorPointBus Expansion Port (allows expansion of up to 12 POINT I/O modules)I/O ConnectionsPower Connections 41971120V acPOINTBlock ac 8 Input/8 Relay Output Module 3To set the node address, set the combination of 1’s and 10’s tocorrespond to the required address. (For example, for 61, set the 10’s switch to 6 and the 1’s switch to 1.)POINTBlock is designed to be grounded through the DIN rail to chassis ground. To assure proper grounding of POINTBlock and POINT I/O adapters and terminal bases to chassis ground, the recommended DIN rail material is zinc-plated, yellow-chromated steel.

The computer can write data intodigital output registers, treating them as I/O ports. The output fromthese registers can then be wired to an interface device, such as arelay. Thus, by sending data to an output register, it is possible toactivate and deactivate a relay. The relay could, in turn, control, forexample, an electric motor.Similarly, a digital input register can be considered as an I/O port that has wires attached to individual bit locations. When read, the datareflects the states of signals on the wires. Digital input registers canbe used to monitor incoming signals. For example, to determinewhether a switch is open or closed, the switch can be wired to theinput of a digital input register.The PCI-1760 Relay Actuator & Isolated Digital Input Card is a PCadd-on card for the PCI bus, which was designed with this idea inmind. This card offers the user 8 opto-isolated digital inputs withisolation protection of 2500 V DC for collecting digital signals undernoisy environment, 8 relay actuators for serving as ON/OFF controldevices or small power switches, and 2 isolated PWM (Pulse WidthModulation) outputs for user's specific applications.Each isolated digital input supports both dry contact and wet contact, designated by jumper settings, so that it can easily interface withother devices. Additionally, for easy monitoring, each relay isequipped with one red LED to reflect its ON/OFF status.Digital filter eliminates unexpected inputnoiseThe PCI-1760 includes a programmable digital filter on each digitalinput channel to eliminate the unexpected signal or noise from thecard's inputs. When the digital filter is enabled, the state of thecorresponding input channel will not update immediately until onehigh/low signal has lasted for a period which is programmed by theuser.2PCI-1760 User's ManualInterrupt function ensures faster systemresponseThe PCI-1760 provides a ìPattern Matchî interrupt function for thedigital input channels. The card monitors the state of some or all ofthe input channels and compares it with a pre-set pattern. When thereceived state matches the pre-set pattern, the card generates aninterrupt signal to the system.The ìChange of Input Stateî interrupt function also monitors the state of the input channels. When any input changes its state, the cardinterrupts the system to handle this event.Up event counter for each DIEach isolated digital input channel is connected to a 16-bit UP eventcounter. A counter will increment by 1 whenever it reads either arising-edge (low to high) or a falling-edge (high to low) input signalwith the maximum frequency of 500 Hz. When the counter overflowsor reaches a pre-set value (programmed by software), it generates aninterrupt signal to the PC.1.2Features•8 opto-isolated digital input channels•8 relay actuator output channels• 2 opto-isolated PWM outputs•LED indicators to show activated relays•Jumper selectable dry contact/wet contact input signals•16-bit Up counter function for each DI•Programmable digital filter function for each DI•Pattern match interrupt function for each DI•Change of input state interrupt function for each DIChapter 1 General Information 31.3Applications•Digital signal and contact status monitoring•Industrial On/Off control•Signal switching•External relay driving1.4SpecificationsIsolated Digital Input•Channels: 8•Opto-isolator: PC354•Input voltage: 5 ~ 12 VHigh: > 4.5 VLow: < 1.0 VUncertain: 1.0V ≤ Vin ≤ 4.5V•Input resistance: 1k Ω @ 1/4 W•Isolation voltage: 2500 V DC•Digital Filter:Minimum effective High input period ≥ [(2 ~ 65535) x 5 ms] + 5 msMinimum effective Low input period ≥ [(2 ~ 65535) x 5 ms] + 5 ms•16-bit UP counter:Maximum effective input frequency: 500HzMinimum High period ≥ 1 msMinimum Low period ≥ 1 ms4PCI-1760 User's ManualRelay Output•Channels: 8•Relay type: single-pole double-throw (SPDT, Form C),but RE2 ~ RE7 are hooked up as single-pole single-throw (SPST)•Output type:RE0 and RE1: NC and NO outputsRE2 ~ RE7: NC or NO outputs (selected by jumper)•Rating contact load: 120 V AC @ 0.5 A or 30 V DC @ 1 A•Contact resistance: less than 100 mΩ initially•Dielectric strength:Coil to contacts (deenergized): 1500 Vrms (1 minute)Between open contacts (deenergized & energized):1000 Vrms (1 minute)•Life expectancy:200,000 operations @ 0.5 A 120 V AC500,000 operations @ 1.0 A 30 V DC•Operating & Releasing time:Operating time: 5 ms max.Releasing time: 5 ms max.Isolated PWM output•Channels: 2•Isolation voltage: 2500 V DC•Scaling resolution: 16 bits (100 µs for each step)High period = [(1 ~ 65535) x 100 µs ] ± 50 µs (max.)Low period = [(1 ~ 65535) x 100 µs ] ± 50 µs (max.)•Output level:High: (5 ± 0.5) VLow: < 0.8 VChapter 1 General Information 5General•Power consumption: +5V @ 450 mA (typical), 850 mA (max.)•Operating temperature: 0 ~ +60° C (32 ~ 140° F)(refer to IEC 68 - 2 - 1, 2)•Storage temperature: -20 ~ +70° C (-4 ~ 158° F)•Operating humidity: 5 ~ 95%RH non-condensing(refer to IEC 68-2-3)•MTBF: over 117,317 hrs @ 25°C, grounded, fixed environmentPhysical•Connector: One 37-pin D-type connector•Dimensions: 175 x 100 mm (6.9" x 3.9")6PCI-1760 User's ManualIG N DID I7-ID I7+ID I6-ID I5-ID I4-ID I3-ID I2-ID I1-ID I0-ID I6+ ID I5+ ID I4+ ID I3+ ID I2+ ID I1+ ID I0+P W M0P W M1R7_O U T R6_O U T R5_O U T R4_O U T R3_O U T R2_O U TR7_C O M R6_C O M R5_C O M R4_C O M R3_C O M R2_C O M R1_N O R1_N C R1_C O MR0_C O M R0_N C R0_N O1.5Pin AssignmentsDescription of pin use:IGND: Isolated Ground for PWMoutputs and dry contact wiring ofIDIIDIn+(n = 0 ~ 7):Isolated digital input+IDIn- (n = 0 ~ 7):Isolated digital input-PWMn (n = 0, 1):Isolated PWM outputRn_OUT (n = 2 ~ 7):Normally Open/Closed pin ofRelay outputRn_NO (n = 0 ~ 1):Normally Open pin of RelayoutputRn_NC (n = 0 ~ 1):Normally Closed pin of RelayoutputRn_COM (n = 0 ~ 7):Common pin of Relay outputChapter 1 General Information 71.6Block DiagramFigure 1.1PCI-1760 Block Diagram 8PCI-1760 User's Manual2.1 Initial InspectionBefore installing the PCI-1760, check the card for visible damage.We have carefully inspected the card both mechanically andelectrically before shipment. It should be free of marks and inperfect order upon receipt.As you unpack the PCI-1760, check it for signs of shipping damage(damaged box, scratches, dents, etc.). If it is damaged or fails to meetspecifications, notify our service department or your local salesrepresentative immediately. Also, call the carrier immediately andretain the shipping carton and packing materials for inspection by the carrier. We will then make arrangements to repair or replace the unit.2.2 UnpackingThe PCI-1760 contains components that are sensitive and vulnerableto static electricity. Discharge any static electricity on your body toground by touching the back of the system unit (grounded metal)before you touch the board.Remove the PCI-1760 card from its protective packaging by grasping the card's rear panel. Handle the card only by its edges to avoid static discharge which could damage its integrated circuits. Keep theantistatic package. Whenever you remove the card from the PC,protect the card by storing it in this package.Y ou should also avoid contact with materials that hold static electrici-ty such as plastic, vinyl and styrofoam.Check the product contents inside the packing. There should be onecard, one CD-ROM, and this manual. Make sure nothing is missing. 10PCI-1760 User's Manual2.3Jumper SettingsWe designed the PCI-1760 with ease-of-use in mind. It is a "plug andplay" card, i.e. the system BIOS assigns the system resources such asbase address and interrupt automatically. There are only threefunctions with 15 jumpers to be set by the user (see Figure 2.1 andTable 2-1). Y ou may refer to the figure below for help in identifyingcard components.Figure 2.1 Location of jumpers and relaysChapter 2 Installation 11Table 2.1: Summary of jumper settingsSetting dry/wet contact connection foreach DIEach of the 8 isolated digital input channels accepts either drycontact or 5 ~ 12 V DC wet contact inputs according to the correspond-ing jumper settings (see Table 2.2). The default setting for each IDI is dry contact. For detailed information, please refer to Chapter 3.Setting relay outputs to be NC/NO6 relay outputs, RE2 ~ RE7, are single-pole single-throw (SPST),which can be jumper set as either nornally open (NO) or normallyclose (NC) (see Table 2.3). The default settings for RE2 ~ RE7 arenormally open. For detailed information, please refer to Chapter 4.Note!: RE0 and RE1 are Form C relays12PCI-1760 User's ManualChapter 2 Installation 13Table 2.2: IDI and corresponding jumperTable 2.3: Relay output and corresponding jumperSetting the time to reset the relay outputsSome users will want the capability of clearing each relay output when the system (or PC) issues a reset signal on the PCI bus. Some users will want to clear their relays only as part of system power-on.The PCI-1760 satisfies both these needs by providing jumper JP14.Depending on the application, this capability may allow relay outputs to be "OFF" without requiring a complete shutdown of processes controlled by the card.Complete loss of power to the chip clears the chip memory. Thus, no matter how JP14 is set, if the power to the PCI-1760 is disconnected,the relay initial power-on state will be "OFF" (NC or NO, depending on the user's settings).2.4Installation InstructionsThe PCI-1760 can be installed in any PCI slot in a computer. Howev-er, to avoid any mistakes or dangerous conditions, please refer to your computer user's manual before you follow the installation procedurebelow:1. Turn off your computer and any accessories connected to thecomputer.Warning!TURN OFF your computer power supply wheneveryou install or remove any card, or connect anddisconnect cables.2. Disconnect the power cord and any other cables from the back ofthe computer.3. Remove the cover of the computer.4. Select an empty 5 V PCI slot. Remove the screw that secures theexpansion slot cover to the system unit. Save the screw to securethe interface card retaining bracket.5. Carefully grasp the upper edge of the PCI-1760. Align the hole inthe retaining bracket with the hole on the expansion slot and alignthe gold striped edge connector with the expansion slot socket.Press the card into the socket gently but firmly. Make sure the cardfits the slot tightly.6. Secure the PCI-1760 by screwing the mounting bracket to the backpanel of the computer.7. Attach any accessories (37-pin D type cable, wiring terminal board,etc.) to the card.8. Replace the cover of your computer. Connect the cables youremoved in step 2.9. Turn the computer power on.14PCI-1760 User's Manual16PCI-1760 User's ManualID InID In : Isolated digital input (n = 0 ~ 7)3.1 OverviewThe PCI-1760 provides 8 opto-isolated digital input channels with 2500V DC isolation. In addition to supporting both dry and wetcontacts, this card provides "Digital Filter", "Pattern Match", "Change of State" and 16-bit UP counter functions for each digital input channel. All these functions are optional. Users can enable/disable each function to fit their applications. Figure 3.1 is a simplified function logic block diagram for the PCI-1760's digital inputs. The following sections will introduce these useful functions.Figure 3.1: PCI-1760 function logic block diagram3.2 Dry Contact Support for Each IDIEach of the 8 isolated digital input channels accepts either dry contact or 5 ~ 12 V DC wet contact inputs as determined by the corresponding jumper settings (see Table 2.1 and Table 2.2). Dry contact capability allows an input channel to respond to changes in an external circuit (e.g., the closing of a switch in the external circuit)when no voltage is present in the external circuit. Figure 3.2 shows the internal and external circuitry, with both wet and dry contact components connected as an input source for one of the PCI-1760's isolated digital input channels.Note!:The default settings of jumpers JP0 ~ JP7 are drycontact, just as shown in Figure 3.2.Figure 3.2: Dry and wet contacts3.3 Digital FilterEach digital input channel has a programmable digital filter foreliminating unexpected signals and noise from the card circuitry. The user can set different digital filtering parameters for each inputchannel in different applications. The following is a functionaldescription of the digital filter.1.When a digital filter is enabled, the PCI-1760 will sample thesignals at the enabled input channel at a 5 ms sampling rate.2.When a high or low signal is present at a digital input channelwhose digital filter function is enabled, the signal will be filteredout as noise unless it lasts for an effective period.3.The effective period is determined by multiplying the samplingrate (5 ms) by the sampling number (2 ~ 65535) chosen by the user,i.e.Effective period = Sampling number x 5 ms.Chapter 3 Digital Input Programming 17Note!: The sampling numbers for High and Low signals can be different. For example, assuming that the samplingnumbers are 10 for a High signal and 15 for a Low signal,the state of the digital input channel will update if a highsignal lasts for 50 ms or more, or a low signal lasts for75 ms or more.Note!: For digital input channels whose digital filter functions are not enabled, the PCI-1760 samples the signals at theseinput channels at a 100 µs sampling rate and immediate-ly updates the state of these input channels when thesignal changes.3.4 Pattern MatchThe PCI-1760 provides a pattern match interrupt function on itsdigital input channels. It monitors the status of the enabled inputchannels, and compares these with a pre-set pattern. When the actualstate matches the pre-set pattern, the PCI-1760 delivers an interruptsignal to the system. This function releases the CPUfrom the burdenof polling all the I/O points, enabling a PC to handle more I/O pointswith higher performance. An example follows:Example 3.1 Assume that the pattern match function is enabled forthe isolated digital input channels IDI1, IDI2, IDI6 and IDI7 (i.e. IDI0, IDI3, IDI4, and IDI5 are ignored during the pattern match process).Then the user can set the pattern match values for the enabled inputchannels. The table below shows one possibility.In thes example, when IDI1, IDI2 and IDI7 are high and IDI6 is low, an interrupt signal will be generated. No matter what the status of IDI0,IDI3, IDI4 and IDI5 are, these will not affect the result.18PCI-1760 User's Manual3.5 Change of Input StateThe PCI-1760 also provides a change of state interrupt function oneach digital input channel allowing users to monitor the status of theenabled digital input channels more efficiently. When one of theenabled channels changes its state, the PCI-1760 delivers an interrupt signal to the system to handle this event. The function can be set togenerate an interrupt for a rising edge signal, a falling edge signal, ora signal with both edges, depending on user application require-ments. The following is an example.Example 3.2 Assume that the change of input state function for theisolated digital input channels IDI1, IDI2, IDI6 and IDI7 is enabled(i.e. the signals at IDI0, IDI3, IDI4 and IDI5 are ignored by the changeof state function). When a change of state occurs in IDI1, IDI2, IDI6or IDI7, an interrupt signal is sent to the system.3.6 CounterEach digital input channel is connected to a 16-bit UP event counterwith a maximum frequency of 500 Hz. Each counter is enabled ordisabled by software. The following describes its major functions:1. Counter reset valueEach counter has its own reset value. When most cards are poweredon, the start-up value of a counter is zero, but in the PCI-1760, usersare allowed to set the reset value to a number between 0 and 65535.This is a very useful feature when one of the counters needs to bestarted from a non-zero number.2. Counter value match interruptAll eight counters also have a counter value match interrupt function.When this interrupt function is enabled, an interrupt signal will begenerated if the counter value reaches a pre-set counter match value.The counter will continue to count until an overflow occurs, then itwill go back to its reset value zero and continue the counting process.Chapter 3 Digital Input Programming 1920PCI-1760 User's ManualQ3. OverflowAn overflow will occur when the counter reaches its maximum value,65535, and an interrupt signal will be generated when this function is enabled.4. Count edgeA user can set each individual channel's counter to count either falling edge (high-to-low) or rising edge (low-to-high) signals. The appropriate setting depends on the initial state of the input signals; if they are low, a rising edge setting would be appropriate.The following figure illustrates counter operation. Counting starts from the counter reset value and continues until it reaches its match value. At that time, an interrupt will also be generated. Afterwards,the counter continues to count until it reaches the maximum capacity of 65535, at which time an overflow interrupt is generated and the counter is reset to its reset value, and continues to count.Figure 3.3: Example for counter operation22PCI-1760 User's ManualThe PCI-1760 provides 8 relay outputs to serve as On/Off control devices. The user can enable and disable each relay output using software commands. For easy monitoring, each relay output isequipped with one red LED to show its On/Off status.Note!: Please refer to Appendix B for more information aboutrelay output software programming.Of these eight relays, two relays (RE0 and RE1) are single-poledouble-throw (SPDT, Form C) and six (RE2 ~ RE7) are single-pole single-throw (SPST), which can be set as either normally open (NO) or normally closed (NC) via jumper settings. The following figureillustrates the structures and connections of the relay outputs.Note!: The default setting for RE2 ~ RE7 is narmally open (NO).Please refer to Chapter 2 for detailed information con-cerning the setting of jumpers.C O MN C /N OREn (n =2 ~ 7)REn (n = 0, 1)JPn+6Figure 4.1: Relay structures and connections24PCI-1760 User's Manual5.1 OverviewThe PCI-1760 also provides two PWM (Pulse-Width Modulation)outputs with 2500 V DC isolation. Each PWM output can be indepen-dently enabled or disabled using software commands.5.2 Introduction to PWMA pulse-width modulated waveform is created when the High and Low periods of a periodic rectangular signal are varied. In the PCI-1760, the user can individually set each channel’s High and Low periods for from 1 to 65535 units (1 unit = 100µs), depending on his needs.The user can also define the “burst count”, the number of cycles generated in each PWM channel. It can be a specific number of cycles or a non-stop cycle. If not a non-stop cycle, the predefined number of cycles must be between 1 and 65535.When the user enables a PWM output, the PCI-1760 will check the PWM burst count value first, If the burst count value is zero, the PWM output will be non-stop. If the burst count value is non-zero, the PWM will output the number of cycles which equals the burst count value,then stop. If the user wants to output another pulse chain, he has to set a new burst count value, then enable the PWM again.Note!: Please refer to Appendix B for more information aboutPWM software programming.L o w p e rio d1 ~ 65535 u n its H ig h p e rio d 1 ~ 65535 u n itsA.1 OverviewThe PCI-1760 is delivered with an easy-to-use 32-bit DLL driver foruser programming under the Windows 95/98/NT operating system. To program the PCI-1760, users are advised to use the 32-bit DLL driverprovided by Advantech to avoid the complexity of low-level pro-gramming by register.When it is necessary to program the PCI-1760 at a register level, themost important consideration is to understand the function of thecard’s registers. The PCI-1760 occupies 128 bytes in the PC’s I/Ospace. In general operations, it only requires 8 I/O spaces, 4 forwriting commands and 4 for reading commands. To enable/disablethe interrupt function, the PCI-1760 requires another 4 I/O spaces toread/write. The address of each register is specified as an offset fromthe card’s base address.A.2OMB0 ~ 3: Outgoing Mailbox BytesWrite OMB3OMB2OMB1OMB0 Address (Hex.)Base + 0x0F Base + 0x0E Base + 0x0D Base + 0x0COMB3:This byte is not currently used.

Users can detect when acommand has been executed by reading its echo in IMB2. When agiven command is executed twice in a very short period, it can bevery difficult to identify the two separate commands just by readingthe command code in IMB2. A simple solution to this problem is towrite a command code “00” between the two identical commands inOMB2. The command code “00” clears the first command code inIMB2 and lets the user clearly recognize execution of the secondcommand. Of course, if a user does not need to distinguish eachseparately executed command, the insertion of the command code“00” between the two identical commands is not necessary.32PCI-1760 User's Manual。

三：功能描述
PLC广泛应用于液压机械，在连接电磁阀时，通常的做法是用继电器转接。
由于继电器的触点是机械式的，存在切换时间长，机械触点寿命短（通常为100万次）的致命缺陷，特别是不能满足频繁快速通断的要求。
FD08-0AB0开关量输出放大板可以将0.3A、0.5A或0.75A晶体管输出转换为3.5A晶体管输出，直接连接DC24V的电磁阀。
具有没有机械触点，寿命长，切换快等特点；且有短路、过流、过压等保护！放大板上有两排指示灯，上面一排是输入信号指示灯，下面一排是输出信号指示灯，可以很明了的知道信号的输入输出。
四：特别说明
虽然放大后输出电流较大，但是不建议一个输出点带两个阀！。
