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 cables for wiring RTD signals;
do not use the cable shield as a signal common (CM) / return path.
▪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).
▪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 Uni-I/O™ 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 RTD Inputs
NOT
E
▪The inputs are not isolated.
▪When connecting 3- or 4-wire RTDs, make sure to use conductors of the same type, width,
and length for all RTD wires, otherwise module accuracy will degrade.
▪When connecting 4-wire RTDs, use 3-wire cable and leave the unused wire unconnected with
minimal length.

Notes:
1. The UIS-04PTN and UIS-04PTKN 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. The UIS-04PTN and UIS-04PTKN inherently supports 3-wire sensors.
4-wire sensors may be connected by utilizing 3 of the sensor wires; in-order to achieve the
specified performance, all sensor wires shall be of identical type and length just as with a 3-wire
sensor connection.
2-wire sensors may also be connected; performance in this case will degrade because of the wires`
resistance.
Refer to the UIS-04PTN and UIS-04PTKN installation guide for detailed installation instructions.
3. 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.
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 resistance
measurements.
7. Sensor connection fault check may interfere with some test equipment like resistance/RTD
simulators and thus may induce reading errors or cause malfunction of the test equipment and/or
the UIS-04PTN and UIS-04PTKN.
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-04PTN and UIS-04PTKN will not check, or report, connection
faults; thus, the reading in such case is unpredictable.
