IO-RO16, IO-RO16-L I/O Expansion Modules 16 Relay Outputs
The IO-RO16 and IO-RO16-L are I/O
expansion modules that can be used in
conjunction with specific Unitronics OPLC
controllers.
The modules are identical except for their
power supply specifications: IO-RO16 runs
at 24 VDC; IO-RO16-L at 12 VDC.
Each module offers 16 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·m).
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 lines used over an extended distance. Use wire
that is properly sized for the load.

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 16 relay outputs. To increase the life span of these contacts and protect the
modules from potential damage by reverse EMF, connect:
a clamping diode in parallel with each inductive DC load, as shown in the left-hand figure below.
an RC snubber circuit in parallel with each inductive AC load, as shown in the right-hand figure below..

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 M90 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.
EX90-DI8-RO8 is a stand-alone I/O module. Even if it is the only module in the configuration, the EX90-DI8-
RO8 is always assigned the number 7.
Its I/Os are addressed accordingly.
Example
Input #5, located on an EX90-DI8-RO8 connected to an M90 OPLC will be addressed
as I 149, 149 = 32 + 7 • 16 + 5
