The K8DT-PM1CN is a DIN rail-mount phase loss and phase sequence monitoring relay from the Omron K8DT series. It detects loss or reversal of any phase on a three-phase 200 – 240 VAC supply and triggers the SPDT relay output when the fault condition persists beyond the set delay time. The delay is adjustable from 0.1 to 30 seconds, allowing to ride through momentary dips or switching transients before de-energizing the load. The relay contact is rated 5 A at 250 VAC, suitable for signalling or directly cutting a motor contactor coil.
