This makes it a fit for under-voltage or over-voltage detection on low-level signals — think thermocouple circuits, shunt outputs, or millivolt transducers in process lines. The adjustable delay from 0.1 to 30 seconds lets you ride through momentary dips without nuisance trips — set it long enough to ignore a pump start transient, short enough to catch a sustained fault. ## Lifecycle Reality — Obsolete, Sourced to Order Omron lists this part as obsolete. ## DIN Rail Fit and Relay Output The K8AB-VS1 snaps onto standard DIN rail — no panel drilling, no adapter plate. The SPDT relay contacts are rated 6 A at 250 VAC, enough to drive a small contactor coil or a PLC input directly. Supply voltage is 24 VAC or 24 VDC, so it works on either a control transformer or a DC power supply without rewiring.","metaTitle":"Omron K8AB-VS1 24VAC/DC Voltage Relay, SPDT, 6-300mV Trip","metaDescription":"Omron K8AB-VS1 24VAC/DC voltage sensing relay, SPDT output, 6-300mV AC/DC trip range, adjustable 0.1-30 sec delay.
