Discrete Inputs
Discrete inputs are used by the EGCP-2 control to determine breaker positions
and accept external control commands. Contacts must change state for a
minimum of 40 milliseconds for the control to sense and register a change in
state. All discrete inputs accept dry contacts only, with contact wetting voltage
provided by the EGCP-2 control. The following is a list of the available EGCP-2
Discrete Inputs:
