Discrete Inputs: Operation Logic

Discrete inputs may be configured to normally open (N.O.) or normally closed (N.C.) states. In the state N.O., no
potential is present during normal operation; if an alarm is issued or control operation is performed, the input is
energized. In the state N.C., a potential is continuously present during normal operation; if an alarm is issued or
control operation is performed, the input is de-energized.
The N.O. or N.C. contacts may be connected to the signal terminal as well as to the ground terminal of the dis-
crete input. See previous chapter Discrete Inputs: Signal on page 36 for details.
