Discrete Inputs: Negative Signal
Discrete Inputs: Opera
Discrete inputs may be configured to be used for normally open (N.O) and normally closed (N.C.) cont cts.
The default condition for N.O. is that th
high and the easYgen will detect an appropriate alarm or status.
T he default condition for N.C. is that the voltage signal is high. If the N.C. contact opens, the signal becomes low
and the easYgen will detect an appropriate alarm or status.
The N.O. o r N.C. contacts may be connected to the signal terminal or to the ground terminal of the discrete input.
See previous chapter Discrete Inputs: Bipolar Signals on page 27 for details.
