Checking the operating status has never
been convenient because of the time it
takes to reach the preset operation time.
The K8AB eliminates this problem by
featuring a flashing alarm indicator that
clearly indicates the operating status.
This has greatly simplified the task of
checking on-site status particularly when
operation settings are changed or an
error occurs.
* Excluding the K8AB-PH and K8AB-TH.
OMRON Low-voltage Monitoring Relays can be used to monitor
3-phase power supplies with 3 or 4 wires simply by changing
DIP switch settings.
