It switches via 4PDT (4 Form C) contacts rated at 3A @ 250VAC, powered by a 100-120VAC supply. The delay is adjustable from 0.5 to 10 seconds via a hand dial, and the timing is initiated by applying input voltage. The hand dial on top lets you tweak the delay without pulling the relay — useful during commissioning when you're dialing in a conveyor sequence or pump-off delay. Listed as active in production — no end-of-life notice.","metaTitle":"Omron H3Y-4 AC100-120 10S Time Delay Relay, 4PDT, 0.5-10 Sec","metaDescription":"Omron H3Y-4 AC100-120 10S time delay relay with 4PDT contacts, 3A @ 250VAC, 100-120VAC supply.
