Example
Controller Settings > Process Control > Process Temp Control
High Temp SP: 100 °
4mA output signal corresponds to a reading of 0 °
20mA output signal corresponds to a reading of
A temperature reading of 50 °, in this case, is represented as a
12mA Aux output signal.
An input of 12mA is represented as an identical 12mA Aux
output signal.
