Installation Guide
The Unitronics®EX-D16A3-TO16 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/Oconnectors. In addition, this module comprises a built-
in adapter for communicating with the PLC and providing power to the other expansion modules in the system.
This module provides:
16 digital inputs, including 1 HSC
3 analog inputs
16 transistor outputs,including 1 HSO

Failure to complywith appropriate safetyguidelines can
cause severe personal injuryor damage to property.
Onlyqualified personnel should service and operate this
device.
When power is turned on, do not connect or disconnect
the device to avoid damaging the system.
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.
Connecting the Module to the PLC
Use the communication cable to connect the module’s PLC expansion port to the PLC.
Take care to connect the correct cable. The connectors of this cable are housed in yellow insulation. Note that one end is
marked To PLC and the other To Adapter; insert accordingly.
The module is supplied with a 1-meter cable, part number EXL-CAB100. Other cable lengths are also available.
Use onlyan original Unitronics cable and do not make anychanges to it.

Wiring Considerations
Use crimp terminals for wiring and use 26-12 AWG wire
(0.13mm2–3.31mm2).
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 correctlysized for the load. Allow for
voltage drop and noise interference with extended input
lines.
Note:Connect the adapter 0Vand the I/O0Vto the same
line
Install an external circuit breaker. Guard against
short-circuiting in external wiring.
Do not connect unused pins. Ignoring this directive
maydamage the device.
To avoid damaging wires,do not exceed a maximum
torque of 0.5 Nm (5 kgf·cm).
Do not use tin, solder, or anysubstance on stripped
wire that might cause the wire strand to break.
Daisy Chaining
To facilitate wiring,you can wire the following pins in series (daisychain). Use both pins provided for this purpose.
Input connector pin: n/p. Output connector pins: +V, 0V. Power connector pins: +V, 0V.
Ensure that the total current drain on anysingle 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:

Individual ConnectionDaisy-chained Connection
Wiring the Power Supply
Always connect the functional earth pin to the earth ground. Use a dedicated wire for this purpose; it must not exceed 1
meter.
Anon-isolated power supplycan be used provided that the 0Vsignal is connected to the earth ground.
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-conformityto voltage power supplyspecifications,connect the device to a
regulated power supply.

Connecting RGPins
For correct operation of digital and analog inputs and for EMI immunity, connect the RG pin of all the expansion modules
containing RG signals to the adapter module 0Vsignal.
The overall length of the wire connecting the RG pins to the adapter 0Vsignal must be less than 3 meters.
Connect the RG pins in series (daisychain). To facilitate this, use both the RG pins.
