IO-D16A3-RO16
XL I/O Expansion Module
Installation Guide
The Unitronics® IO-D16A3-RO16 is an XL I/O expansion module for use in conjunction with specific Unitronics controllers.
XL modules comprise enhanced I/O configurations and detachable I/O connectors. A local or remote I/O adapter module is
required to interface between the expansion module and the PLC controller and provide power to the expansion modules in the
system.
The I/O expansion module provides:
16 digital inputs, including 2 HSC
3 analog inputs
16 relay outputs

Mounting the Module Connecting Modules
To mount the module on a 35mm DIN-rail, snap it squarely onto
the DIN-rail, as shown below.
To connect a module to the adapter or expansion module:
1. Push the module-to-module connector (1) into the port
(2) located on the right side of the module or adapter.
2. Push the protective cap (3) into the connector port of
the last module. The cap is supplied with the adapter.
Install the module in an upright position.
To ensure good ventilation, leave at least 50mm between the
device and all other objects above or below it.
Install at a maximum distance from high-voltage cables and
power equipment.

Wiring Considerations
Install an external circuit breaker. Guard against
short-circuiting in external wiring.
Do not connect unused pins. Ignoring this directive
may damage the device.
To avoid damaging wires, do not exceed a maximum
torque of 0.5 Nm (5 kgf·cm).
Use crimp terminals for wiring and use 26-12 AWG wire
(0.13mm
2
–3.31mm2).
Strip the wire to a length of 7±0.5mm (0.250–0.300”).
Do not route input cables together with output cables
through the same multi-core cable or wire.
Use wire that is correctly sized for the load. Allow for
voltage drop and noise interference with extended input
lines.
Note: Connect the adapter 0V and the I/O 0V to the same line.
Do not use tin, solder, or any substance on stripped
wire that might cause the wire strand to break.
Daisy Chaining
To facilitate wiring, you can wire the following pins in series (daisy chain). Use both pins provided for this purpose.
Input connector pin: n/p. Output connector pins: +V, 0V, C0, C1.
Ensure that the total current drain on any single line does not exceed 10A. If a specific pin requires more than 10A, connect it with
a separate wire. The following diagram demonstrates the wiring options:
Wiring Inputs
The following diagram shows the input connectors with pin numbers and corresponding LED numbers.
Note: Where input numbers are stated, the intention is the LED number.

Wiring Digital Inputs
Inputs may be wired as either pnp (positive logic) or npn (negative logic).
Inputs 4 and 6 can function as high-speed counters, frequency measurers, or general purpose digital inputs (set in software).
Inputs 5 and 7 can function either as counter reset inputs or general purpose digital inputs (set in software).
For information on connecting RG pins, refer to Connecting RG Pins.
