Supply voltage is fixed at 200-240 VAC, so the relay is intended for standard three-phase systems within that range. Output is a single-pole double-throw (SPDT) relay rated 5 A at 250 VAC — sufficient to switch a contactor coil or signal a PLC input. An adjustable delay from 0.1 to 30 seconds prevents nuisance tripping during transient conditions such as motor startup or momentary supply dips. Rated for operation from -20°C to 60°C, covering most industrial environments.","metaTitle":"Omron K8DS-PA1 Phase Sequence/Asymmetry Relay, 200-240VAC","metaDescription":"K8DS-PA1 phase sequence, voltage asymmetry & phase loss relay from Omron. 200-240VAC supply, SPDT 5A output, adjustable 0.1-30s delay.
