The logic relay provides 4 independent operating hours
counters. These operating hours counters enables you to
record the operating hours of systems, machines and
machine parts. An adjustable setpoint can be selected within
the value range. In this way, maintenance times can be
logged and reported. The counter states are retained even
when the device is switched off. As long as the count coil of
the operating hours counter is active, the logic relay counts
the hours in one second cycles.
You integrate an operating hours counter into your circuit in
the form of a contact and coil.
