feature not only provides protection
should a short or overload occur while
the relay is on, but will also provide
protection should the relay be switched
into a short. In either case, the relay will
sense the short circuit condition and
then block it indefinitely until the short is
removed and the unit is reset by cycling
the input control. The second option is a
status output, which provides a built-in-
test function. This feature checks the
input circuitry of the relay and provides a
logic (0) low when the input circuit is
turned on and operational. Both options
are available either together or
separately as standard features.
