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.

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.
Open the door of the Uni-I/O™ module and hold it as shown in the accompanying figure.
Use the upper and lower guide-tunnels (tongue & groove) to slide the Uni-I/O™ module into place.
Verify that the DIN-rail clips located at the top and bottom of the Uni-I/O™ module have snapped onto the DIN-rail.
$Unitronics-UIA-0800N-Uni-Input-Outpu-Modules- $1$$
Slide the Bus Connector Lock all the way to the left as shown in the accompanying figure.
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.
If the module is the last in the configuration, leave the I/O bus connector covered.

Removing a Module

Turn off the system power.
Disconnect the I/O terminals (#2,3,7,8 in the diagram).
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.
On the Uni-I/O™ module, pull the top DIN-rail clip up and the bottom clip down.
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.

UL Ratings, Programmable Controllers for Use in Hazardous Locations, Class I, Division 2, Groups A, B, C and D
These Release Notes relate to all Unitronics products that bear the UL symbols used to mark products that have been approved for use in hazardous locations, Class I, Division 2, Groups A, B, C and D.

Caution

This equipment is suitable for use in Class I, Division 2, Groups A, B, C and D, or Non-hazardous locations only.
Input and output wiring must be in accordance with Class I, Division 2 wiring methods and in accordance with the authority having jurisdiction.
WARNING—Explosion Hazard—substitution of components may impair suitability for Class I, Division 2.
WARNING – EXPLOSION HAZARD – Do not connect or disconnect equipment unless power has been switched off or the area is known to be non-hazardous.
WARNING – Exposure to some chemicals may degrade the sealing properties of material used in Relays.
This equipment must be installed using wiring methods as required for Class I, Division 2 as per the NEC and/or CEC.

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).

Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
Unscrew the terminal to its widest position before inserting a wire.
Insert the wire completely into the terminal to ensure a proper connection.
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:
- 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.

Wiring the Analog Inputs

NOT: The inputs are not isolated.
E: Each input has its own common point (CM0 for I0, etc.).

Notes:

The 4-20mA input option is implemented using 0-20mA input range.
The UIA-0800NH measures values that are up to 1.5% higher than the nominal input range (i.e. Input Over-range). Note that when the input overflow occurs, it is indicated in the corresponding system tag while the input value is registered as the maximum permissible value. The Over-range values can reach up to 20.3mA, and any input current higher than that will still register as 20.3mA while the Overflow system tag is turned on.
Step response and update time are independent of the number of channels that are used.
See LED Indications Table above for description of the relevant indications. Note that the diagnostics results are also indicated in the system tags and can be observed through the UniApps™ or the online state of the UniLogic™.
