Modules
User Guide
UID-W1616R, UID-W1616T
Uni-I/O™ Wide is a family of Input/Output modules that are compatible with the
UniStream™ control platform. Wide Modules are 1.5 times as wide as Uni-I/O™ modules,
and comprise more I/O points in less space.
This guide provides basic installation information for UID-W1616R and UID-W1616T Uni-
I/O™ modules.
Technical specifications may be downloaded from the Unitronics website.
The UniStream™ platform
comprises CPU controllers, HMI
panels, and local I/O modules
that snap together to form an
all-in-one Programmable Logic
Controller (PLC).
Install Uni-I/O™ modules:
▪Onto the back of any
UniStream™ HMI Panel
comprising a CPU-for-Panel.
▪Onto a DIN-rail, using a
Local Expansion Kit.
The maximum number of Uni-I/O™ Wide modules that can be connected to a single CPU
controller is limited. For details, please refer to the specification sheets of the
UniStream™ CPU or any of the relevant Local Expansion Kits.
Before You Begin
Before installing the device, the installer must:
▪Read and understand this document.
▪Verify the Kit Contents.
Installation option requirements
If you are installing a Uni-I/O™ module onto:
▪A UniStream™ HMI Panel; the Panel must comprise a CPU-for-Panel, installed according
to the CPU-for-Panel installation guide.
▪A DIN-rail; you must use a Local Expansion Kit, available by separate order, to integrate
the Uni-I/O™ modules on the DIN-rail into a UniStream™ control system.

About the I/O Bus Connectors
The I/O Bus connectors provide the physical and electrical connection points between
modules. The connector is shipped covered by a protective cover, protecting the connector
from debris, damage, and ESD.
The I/O Bus - Left (#4 in diagram) can be connected to either a CPU-for-Panel, a
Uni-COM™ Communication module, to another Uni-I/O™ module or to the End Unit of a
Local Expansion Kit.
The I/O Bus - Right (#6 in diagram) can be connected to another I/O module, or to the
Base Unit of the Local Expansion Kit.
Caution
▪If the I/O module is located last in the configuration, and nothing is to be
connected to it, do not remove its Bus Connector Cover.
Installation
▪Turn off system power before connecting or disconnecting any modules or devices.
▪Use proper precautions to prevent Electro-Static Discharge (ESD).
Installing a Uni-I/O™ Module onto a UniStream™ HMI Panel
NOTE
The DIN-rail type structure on the back of the panel provides the physical support for
the Uni-I/O™ module.
1. Check the unit to which you will connect the Uni-I/O™ module to verify that its Bus
Connector is not covered.
If the Uni-I/O™ module is to be the last one in the configuration, do not remove the
cover of its I/O Bus Connector - Right.
2. Open the door of the Uni-
I/O™ module and hold it as
shown in the accompanying
figure.
3. Use the upper and lower
guide-tunnels (tongue &
groove) to slide the Uni-
I/O™ module into place.
4. Verify that the DIN-rail clips
located at the top and
bottom of the Uni-I/O™
module have snapped onto
the DIN-rail.

5. Slide the Bus Connector Lock all the way to
the left as shown in the accompanying figure.
6. If there is already a module located to its
right, complete the connection by sliding the
Bus Connector lock of the adjacent unit to the
left.
7. If the module is the last in the configuration,
leave the I/O bus connector covered.
Removing a Module
1. Turn off the system power.
2. Disconnect the I/O terminals (#2,3,7,8 in the diagram).
3. Disconnect the Uni-I/O™ module from the adjacent units: slide its Bus Connector Lock
to the right. If there is a unit located on its right, slide the lock of this module to the
right as well.
4. On the Uni-I/O™ module, pull the top DIN-rail clip up and the bottom clip down.
5. Open the door of the Uni-I/O™ module and hold it with two fingers as shown in the
figure on page 3; then pull it carefully from its place.
Installing Uni-I/O™ modules onto a DIN-rail
To mount modules onto a DIN-rail, follow steps 1-7 in Installing a Uni-I/O™ Module onto a
UniStream™ HMI Panel on page 3.
In order to connect the modules to a UniStream™ controller, you must use a Local
Expansion Kit.
These kits are available with and without power supplies, and with cables of varying
lengths. For complete information, please refer to the installation guide of the relevant
Local Expansion Kit.
Numbering Modules
You can number modules for reference purposes. A set of 20 stickers is provided with
every CPU-for-Panel; use these stickers to number the modules.
▪The set contains numbered and blank
stickers as shown in the figure to the left.
▪Place them on the modules as shown in the
figure to the right.

Unitronics
▪Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V
point.
▪Do not touch live wires.
▪All wiring activities should be performed while power is OFF.
▪Use over-current protection, such as a fuse or circuit breaker, to avoid excessive
currents into the Uni-I/O™ module supply port.
▪Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
▪Double-check all wiring before turning on the power supply.
Caution
▪To avoid damaging the wire, use a maximum torque of 0.5 N·m (5 kgf·cm).
▪Do not use tin, solder, or any substance on stripped wire that might cause the
wire strand to break.
▪Install at maximum distance from high-voltage cables and power equipment.
Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2–3.31 mm2).
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 a proper connection.
4. Tighten enough to keep the wire from pulling free.
Uni-I/O™ Module Connection Points
All wiring diagrams and instructions in this document refer to the I/O connection points of
the different modules. These are arranged in four groups of eleven points each, as shown
in the figures below.

Wiring Guidelines
In order to ensure that the device will operate properly and to avoid electromagnetic
interference:
▪Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.
▪Use wires that are properly sized for the load.
▪Route each I/O signal with its own dedicated common wire. Connect common wires at
their respective common (CM) points at the I/O module.
▪Individually connect each 0V point in the system to the power supply 0V terminal.
▪Individually connect each functional earth point ( ) to the earth of the system
(preferably to the metal cabinet chassis). Use the shortest and thickest wires possible:
less than 1m (3.3’) in length, minimum thickness 14 AWG (2 mm2).
▪Connect the power supply 0V to the earth of the system.
NOTE
For detailed information, refer to the document System Wiring Guidelines, located in
the Technical Library in the Unitronics’ website.

Wiring Relay Outputs: UID-W1616R
Output's power supply
The relay outputs require an external 24VDC power supply. Connect the 24V and 0V
terminals as shown in the figure below.
▪To avoid risk of fire or property damage, always use a limited current source or
connect a current limiting device in series with the relay contacts.
▪The 0V of the module must be connected to the HMI Panel’s 0V.
Ignoring this directive may damage the device.
▪In the event of voltage fluctuations or non-conformity to voltage power supply
specifications, connect the module to a regulated power supply.
UID-W1616R
The outputs are arranged in two
isolated groups:
▪O0-O7 share common CM2
▪O8-O15 share common CM3
Wire each group according to the accompanying figure.
Increasing contact life span
To increase the life span of the relay 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.
