4-20 mA and Voltage Sensors
The 4-20mA Sensor can be used for current measurements (within a range of 0 - 30 mA) and the Voltage
Sensor - for voltage measurements (within a range of -32 to +32 VDC).
Under the “Sensors” menu, it is possible to enable conversion from mA/V to other values depending on
transducer type connected to mA/V Sensor.
If required, switch the Conversion on, and use the drop-down menu to choose a predefined Dimension and
Unit. If the required Dimension or Unit is not in the list, choose “Other” as the Dimension and input your own
measurement unit.
Define the reference values for two measurement points (i.e., sensor’s min/max voltage). For example, set
0 V equal to 100 of your units and 32V equal to 1000 of your units. The values will then be linearly calculated
according to these two reference points.
