Chapter 5 Input and Output Module

Specifications

This chapter provides an overview of available I/O modules for each of the l/O families. A typical I/O module from each different module type is described in detail. This chapter describes the type of information you will find in the l/O module installation instructions that you will receive with your I/O modules.

I/O MODULE SPECS 5-1

800 Series Input/Output Module Overview

All I/O modules fall into one of four possible categories; discrete, register, analog, or intelligent modules. Discrete input modules provide multiple points of information to the PLC that must be either ON or OFF. Discrete output modules receive signals from the controller and turn field devices either ON or OFF.

Register input modules are modules that are used to select, convert, and condition BCD or binary data (16 bit words) that passes between an input field device and the PLC. Register output modules provide lTL or CMOS compatible signals (16 Bit words), in either BCD or binary format, to output field devices.

Analog input modules receive a voltage or current from a field device and perform an analog to digital conversion. It then presents the digital results (16 bit words) to the PLC. Analog output modules receive digital data (16 bit words) from the PLC, perform a digital to voltage or current conversion. It then presents the analog result to field devices.

Intelligent modules may be defined as’ modules with built-in microprocessors that perform functions that would otherwise require use of the PLC’s main memory, and Central Processing Unit.

5-2 I/O MODULE SPECS

I/O Terminal Connectors

Field wiring is connected to the I/O module via the terminal block. Most terminal blocks are attached to the l/O housing, not the modules. When it becomes necessary to replace an I/O module, the module slides out from the l/O housing while the terminal block remains attached to the housing. This allows you to quickly and easily replace I/O modules, without disrupting field wiring. 800 series analog l/O modules use a terminal block that plugs into the I/O module, not the housing. In this case you must unplug the terminal block from the module before you exchange the module. The field wiring remains with the connector and is not disrupted with this system.

I/O Module Keying System

The 800 series l/O housings have an optional l/O module keying system that prevents improper I/O module placement.

NOTE Improper module placement could cause damage to the I/O module or field device. It is highly recommended that the keying system be used.

Each module type has a specific key pattern that is set at the factory by Modicon. To implement the key system you insert the key pins (supplied by Modicon) into the housing so that the key pins mate with the pattern of holes on the module designated for a given slot. When implemented, only modules of the same type can be inserted in a given slot. An adequate number of key pins are shipped with the housings as part of hardware kit AS-8536-002.

Register Input Module The 8865-001 is an eight channel register input module that accepts either eight binary or eight BCD 16 bit numbers. The 8865-001 may receive data from up to eight different field devices. These devices are electrically connected together at the module and must be isolated from each other to prevent loading the bus. Each of the eight channels has it’s own strobe line that determines which device is on the data input bus to the module. Two toggle switches are located on the side of the module, near the top. One determines if the module is looking for a TRUE HIGH or TRUE LOW signal. The other determines if the input data should be treated as binary or BCD data. An ACTIVE indicator is ON when the controller is running and the module is communicating properly with the controller. The FIELD ACTIVE indicator is ON when the module is communicating with the field devices. The module has a color coded stripe to facilitate quick module identification.

Intelligent Module The B883-001 is a high speed counter module that consists of two separate and independent counters and associated logic, and controls up to three outputs. After being configured, the module can operate independently of the 984, reacting faster to events than the controller’s scan time would allow. The module counters have the following characteristics:

Counter 1 has bi-directional count capability and has two inputs, two set points, a programmable maximum count, and two outputs. Counter 1 will also accept input from quadrature devices such as incremental encoders.

Counter 2 is an up counter and has one input, a programmable maximum count, and one output.

Both counters accept pulsed inputs of 0 to 5, 0 to 12 or 0 to 24VDC.

The B883 options are selected by commands from the PLC and by terminal block wiring.

The ACTIVE indicator is ON when the controller is running and the module is communicating properly with the controller. The PWR indicator is ON when the module has power and is ready to operate. The FIELD PWR indicator is on when the reference voltage is present. The OUTPUT #l indicator is on when the output is on. The OUTPUT #2 indicator is on when the output is on. The MAX COUNT indicator is ON when counter #2’s output is ON (i.e., reached the programmed maximum count).

NOTE In RTD applications, the internal precision source forces a 2.5 mA current through the resistance,. For a PT 100 RTD, a range of 18.49 Q . . . 390.25 Q would correspond to -200 . . . +850 degrees C; the values 80.31 Q (-50 degrees C) to 194 Q (=250 degrees C) are in the recommended range. Consult your RTD data book for the appropriate linearization equations for your field device.

When the module goes out of range -- either over or under range -- and then returns to a valid operating range, the module will resume proper operations unless the out of range condition reaches or exceeds the safety range of +/- 24 VDC.

CAUTION Operation at an extreme out of range voltage -- at or beyond +/- 24 VDC -- will cause permanent damage to the module.


LED

The ADU 204 has one green LED opposite terminal screw 1, indicating the presence of the 5V power supply from the backplane.

Noise Suppression DIP Switch

A two-position DIP switch on the back of the ADU 204 can be set to protect the module from external noise interference. The factory setting is for 50 HZ voltage interferences; by alternating the switch position as shown below, the module is set for 60 Hz noise suppression.

Over Range

When the module goes out of range -- either over or under range -- and then returns to a valid operating range, the module will resume proper operations unless the out of range condition reaches or exceeds the safety range of +/- 30 VDC.

CAUTION Operation at an extreme out of range voltage -- at or beyond +/- 30 VDC -- will cause permanent damage to the module.

LED

The ADU 204 has one green LED opposite terminal screw 1, indicating the presence of the 5V power supply from the backplane.


DIP Switch Settings

Two, two-position DIP switches are located on the back of the ADU 205: Switch 2 is used to specify whether the inputs are voltage or current inputs; Switch 1 can be set to protect the module from external noise interference.

Verify the calibration adjustment on the other three analog channels: for channel 2, wire terminals 7, 9 and 10 to the voltage standard; for channel 3, use terminals 14,16 and 17; for channel 4, use terminals 18, 20 and 21. If you make any fine tuning adjustments on any of thee channels, verify their effects on channel 1.

When the readings on all four channels are satisfactory, drop a bead of sealing varnish on the potentiometer to secure the setting.

Step 1 Wire terminal 4 to the positive side and terminal 5 to the negative side of a 4-l/2 digit voltmeter for analog channel 1.


Step 2 Set the voltage standard to +l- V and adjust the gain potentiometer for channel 1 until a reading of 400 counts is obtained.

Step 3 Set the voltage standard to -lOV and adjust the offset potentiometer for channel 1 until a reading of 0 counts is obtained.

Step 4 Check the accuracy of your midrange setting by setting the voltage standard to OV; the reading should be at or within a count of 2000 counts. Recheck the high range count by setting the voltage standard to +lOV; the reading should be 4000. Recheck the low range count by setting the voltage standard to -lOV; the reading should be 0.

Step 5 To fine tune the calibration adjustment repeat steps 2 . . . 4 until the best reading is obtained. When the reading is satisfactory, drop a bead of sealing varnish on the two adjusted potentiometers.
