IO-DI16 I/O Expansion Module 16 Digital Inputs

The IO-DI16 is an I/O expansion module

that can be used in conjunction with

specific Unitronics OPLC controllers.

The module offers 16 digital inputs in 2

groups, type pnp/npn (source/sink).

The interface between the module and

the OPLC is provided by an adapter.

The module 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

Wire Size

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

Wiring Considerations

 Note that the adapter and input signals must be connected to the same 0V signal.

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

 We recommend that you use crimp terminals for wiring.

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

General Wiring Procedures

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 touch live wires.

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

Input Wiring

 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.

 Each group of inputs may be wired as either pnp or npn inputs.

Addressing I/Os on M90 Expansion Modules

Inputs and outputs located on I/O expansion modules that are connected into an M90 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
