Discrete Inputs
Discrete Inputs: Signal Polarity
The discrete inputs are electrically isolated which permits the polarity of the connections to be either positive or
negative.
NOTE
All discrete inputs must use the same polarity, either positive or negative signals, due to the common
ground.
Discrete Inputs: Positive Polarity Signal
