Trip range is 1 to 150 V AC/DC, so it handles low-voltage control circuits, battery banks, or small transformer secondaries. The SPDT relay output is rated 5 A at 250 V AC, enough to drive a contactor coil or alarm annunciator. Adjustable delay from 0.1 to 30 seconds lets you ride through momentary dips without cycling the output — critical on a motor feed or PLC supply. Snaps onto standard DIN rail. Supply voltage is 100 to 240 V AC, so it can share the same rail with contactors or power supplies without a dedicated transformer. Wire the monitored voltage to the sensing input; the trip threshold is set via a front-panel potentiometer (scale printed on the housing). No forced cooling needed.","metaTitle":"Omron K8AK-VW2 100-240VAC Voltage Sensing SPDT Relay","metaDescription":"Active Omron K8AK-VW2 100-240VAC voltage sensing relay, SPDT output, trip range 1 to 150V AC/DC, delay 0.1-30 sec.
