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.
▪Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents into the
UIS-08TC 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 mm 2 –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.
UIS-08TC Connection Points
All wiring diagrams and instructions in this document
refer to the UIS-08TC connection points.
These points are arranged in four groups of seven points
as shown in the figure to the right.

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 shielded cables for wiring thermocouple signals and shielded twisted pair cables for wiring analog
input voltage signals;
do not use the cable shield as a signal common / return path.
▪It is recommended to short unused analog inputs (Tx- to Tx+).
▪Route each I/O signal with its own dedicated common wire. Connect common wires at their respective
common points (Tx-) at the I/O module.
▪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 UIS-08TC
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 Inputs
NOTE
▪Each input offers two modes: thermocouple or voltage. You can set each input
independently. The mode is determined both by wiring and by the hardware
configuration within the software application.

Notes:
1. The UIS-08TC measures values that are slightly higher or lower than the nominal input range
(i.e. Input Over/Under-range respectively).
Note that when input Overflow, Underflow or a connection fault occurs, it is indicated in the
corresponding I/O Status tag (refer to the UniLogic™help for details) as well as by the respective
input LED (see LED Indications), while the input value is registered as follows:
Fault Type
Registered Value in the Input Tag
Overflow
32,767
Underflow
-32,767
Connection fault
-32,768
2. For temperature measurement, the value is represented in 0.1° units. For example, a temperature
Of 12.3° is represented as 123 at the Value tag.
3. The internal cold junction accuracy is ±1°C for all thermocouple types. This accuracy adds to the
accuracy in the table. The module requires at least 30 minutes of warm-up in order to meet the
table specifications.
4. Step response and update time are independent of the number of inputs that are used.
5. See LED Indications Table above for description of the relevant indications. Note that the
diagnostics results are also indicated in the I/O tags and can be observed through the UniApps™
or the online state of the UniLogic™.
6. Sensor connection fault check is active by default for both temperature and voltage measurements.
7. Sensor connection fault check may interfere with some test equipment like thermocouple/voltage
simulators and thus may induce reading errors or cause malfunction of the test equipment and/or
the UIS-08TC.
In order to interoperate correctly with such equipment, you may set the Disable Fault Detection I/O
tag. This will disable connection fault check for all inputs.
Note that when this tag is set, the UIS-08TC will not check, or report, connection faults; thus, the
reading in such case is unpredictable.
