Normally Energized
•
Although the output of each relay can be externally wired for either normally open
(NO) or normally closed (NC) operation, it is also possible to determine the default
“energized” state for the relay. Normally open and normally closed are the
indication of the default contact states when the relay is de-energized.
•
The advantage of having a relay configured for normally energized operation is that
in the event of the rack losing power, the relay would immediately switch to a fault
condition.
