The UIS-WCB1 utilizes two high speed blocks that can each be assigned either to the inputs or to
the outputs.
Four of the digital inputs may be configured to function either as normal, or as high speed digital
inputs, that can receive high speed pulse signals from up to two sensors or shaft encoders.
The two transistor outputs may be configured to function either as normal, or as high speed PWM
outputs.
The 4-20mA input option is implemented using 0-20mA input range.
The UIS-WCB1 analog inputs measure values that are slightly higher than the nominal input range
(Input Over-range).
Note that when the input overflow occurs, it is indicated in the corresponding I/O Status tag while
the input value is registered as the maximum permissible value. For example, if the specified input
Unitronics

09/15
UniStream™
range is 0 ÷ 10V, the Over-range values can reach up to 10.15V, and any input voltage higher than
that will still register as 10.15V while the Overflow system tag is turned on.

See LED Indications Table 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™.
Step response and update time are independent of the number of channels that are used.
The UIS-WCB1 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-WCB1 installation guide for detailed installation instructions.
The UIS-WCB1 temperature inputs measure values that are slightly higher or lower than the
nominal input range (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
10. 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.
11. The overall accuracy for thermocouples is a combination of the per-sensor specified accuracy and
the thermocouple cold junction error specification.
The module requires at least 30 minutes of warm-up in order to meet the accuracy specifications.
12. Sensor connection fault check is active by default for temperature, resistance and mV
measurements. This may interfere with some test equipment like RTD, thermocouple, resistance
and voltage simulators and thus may induce reading errors or cause malfunction of the test
equipment and/or the UIS-WCB1.
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-WCB1 will not check, or report, connection faults; thus, the
reading in such case is unpredictable.
13. Life expectancy of the relay contacts depends on the application that they are used in. The
product’s installation guide provides procedures for using the contacts with long cables or with
inductive loads.
14. The UIS-WCB1 analog outputs are able to output values that are slightly higher or lower (if
applicable) than the nominal output range (Output Over/Under-range respectively).
