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.
Use shielded twisted pair cables for wiring Analog I/O signals;
do not use the cable shield as a signal common (CM) / return path.
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 and each common (CM) point in the system to the
power supply 0V terminal, unless otherwise specified.
Individually connect each functional ground 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.
Earthing the cables' shield:
Connect the cable shield to the earth of the system - preferably to the metal cabinet
chassis. Note that the shield must be connected only at one end of the cable;
typically, earthing the shield at the UIA-0006 end performs better.
Keep shield connections as short as possible.
Ensure shield continuity when extending shielded cables.
NOTE
For detailed information, refer to the document System Wiring Guidelines, located in
the Technical Library in the Unitronics’ website.
Wiring the Power Supply
This module requires an external 24VDC power supply.
In the event of voltage fluctuations or non-conformity to voltage power supply
specifications, connect the device to a regulated power supply.
Connect the 24V and 0V terminals as shown
in the accompanying figure.

Wiring the Analog Outputs
NOTE
Each output offers two modes: voltage or current. You can set each output
independently. The mode is determined both by wiring and by the hardware
configuration within the software application.
Voltage and current modes use distinct points. Connect only the point associated
with the selected mode; leave the other point unconnected.
Each output has its own common point (CM0 for O0 etc). Connect each analog
output using its corresponding CM point.
Do not connect the common point (CM) to the 0V point.
Do not use the common points (CM) for any purpose other than connecting the
analog output load. Using them for any other purpose may damage the module.

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™ 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
N OTE
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.
Remo ing 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™ 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. 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.
