IO-DI8-RO8, IO-DI8-RO8-L I/O Expansion Modules 8 Inputs, 8 Outputs

The IO-DI8-RO8 and IO-DI8-RO8-L are I/O

expansion modules that can be used in

conjunction with specific Unitronics OPLC

controllers.

The modules are identical except for their

voltage specifications: IO-DI8-RO8 runs at

24 VDC; IO-DI8-RO8-L at 12 VDC.

Both modules offer 8 digital inputs, type

pnp/npn (source/sink), and 8 relay outputs.

The interface between a module and the

OPLC is provided by an adapter.

These modules may either be snap-

mounted on a DIN rail, or screw-mounted

onto a mounting plate.

Connecting Expansion Modules

An adapter provides the interface between the OPLC and an expansion module. To connect the I/O module to

the adapter or to another module:

1. Push the module-to-module connector into the port located on the right side of the device.

Note that there is a protective cap provided with the adapter. This cap covers the port of the final

I/O module in the system.

To avoid damaging the system, do not connect or disconnect the device when the

power is on.

Wiring

Do not touch live wires.

Unused pins should not be connected. Ignoring this directive may damage the device.

Do not connect the ‘Neutral or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.

Double-check all wiring before turning on the power supply.

Wiring Procedures

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm 2–3.31 mm2) for all wiring purposes.

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).

2. Unscrew the terminal to its widest position before inserting a wire.

3. Insert the wire completely into the terminal to ensure that a proper connection can be made.

4. Tighten enough to keep the wire from pulling free.

To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).

Do not use tin, solder, or any other substance on stripped wire that might cause the wire strand to break.

Install at maximum distance from high-voltage cables and power equipment.

I/O Wiring—General

Input or output cables should not be run through the same multi-core cable or share the same wire.

Allow for voltage drop and noise interference with input/output lines used over an extended distance.

Use wire that is properly sized for the load.

The adapter and I/O signals must be connected to the same 0V signal.

Wiring the Outputs’ Power Supply

Wiring DC supply

1 Connect the "positive" cable to the "+V" terminal, and the “negative” to the "0V" terminal.

A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.

Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.

In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the

device to a regulated power supply.

Notes: 1. The adapter and output’s power supply must be connected to the same 0V signal.

Increasing Contact Life Span

Both modules have 8 relay outputs. To increase the life span of these contacts and protect the module from

potential damage by reverse EMF, connect:

a clamping diode in parallel with each inductive DC load,

an RC snubber circuit in parallel with each inductive AC load.

specifications are those of a normal digital input.

Addressing I/Os on Expansion Modules

Inputs and outputs located on I/O expansion modules that are connected to an OPLC are assigned addresses

that comprise a letter and a number. The letter indicates whether the I/O is an input (I) or an output (O). The

number indicates the I/O’s location in the system. This number relates to both the position of the expansion

module in the system, and to the position of the I/O on that module.

Expansion modules are numbered from 0-7 as shown in the figure below.

01234567

Expansion module

identification number

Adapter

The formula below is used to assign addresses for I/O modules used in conjunction with the OPLC.

X is the number representing a specific module’s location (0-7). Y is the number of the input or output on that

specific module (0-15).

The number that represents the I/O’s location is equal to:

32 + x • 16 + y

Examples

Input #3, located on expansion module #2 in the system, will be addressed as I 67,

67 = 32 + 2 • 16 + 3

Output #4, located on expansion module #3 in the system, will be addressed as O 84,

84 = 32 + 3 • 16 + 4.
