Operating hours counter EZ provides 4 independent operating hours counters. These
operating hours counters enable 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,
EZ counts the hours in second cycles.
You integrate an operating hours counter into your circuit in
the form of a contact and coil.
