User Guide
UIA-0800NH
Uni-I/O™is a family of Input/Output modules that are compatible with the UniStream® control
platform.
This guide provides basic installation information for the UIA-0800NH module.
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™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™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
8. Turn off the system power.
9. Disconnect the I/O terminals (#2,3,7,8 in the diagram).
10. 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.
11. On the Uni-I/O™module, pull the top DIN-rail clip up and the bottom clip down.
12. 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. 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.

Wiring
▪This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power environments.
▪All power supplies in the system must include double insulation. Power supply outputs must be
rated as SELV/PELV/Class 2/Limited Power.
▪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.
▪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.
UIA-0800NH Connection Points
All wiring diagrams and instructions in this document
refer to the UIA-0800NH connection points.
These points are arranged in four groups of 7 points as
shown in the figure to the right.
Two top groups
Input connection points (0,1,2,3)
Two bottom groups
Input connection points (4,5,6,7)
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:

UG_UIA-0800NH
User Guide

➢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-0800NH 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.
