DESCRIPTION
ZD20CF Series Relays have optical isolation between
relay input and output. Loads may be connected
to either the positive or negative output terminals.
ZD20CF Relays act as electronic circuit breakers
that sense shorted loads or other overload events
and then trip-off. Relay contacts open and no current
ows through the relay and associated loads. These
relays prevent overcurrent damage to the system.
Cycling the relay on-off removes the tripped or
latched-off condition and returns the relay to the
normal operating state.
