Should it be mandatory to utilize control of semiconductor driven CB by a hybrid DO an
interposing tripping relay is required, as illustrated in the following drawing, between the DO
and electronics of the CB.
For Use of interposing trip relay between hybrid DO and electronics of circuit breaker; refer the atatched snapshot.
for Principle diagram of hybrid DI/DO module showing constant current flow , refer the attached snapshot
NOTE: Never use hybrid outputs to control semiconductor driven circuit breakers directly
