Product details

The Omron H3Y-4 AC100-120 10S is a mechanical time delay relay in the H3Y series, offering both off-delay and on-delay functions. 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.

Frequently asked questions

What is the delay range and how is it set?

The delay is adjustable from 0.5 to 10 seconds via a hand dial on the relay body. Timing is initiated when the input voltage (100-120VAC) is applied.

What contact configuration and rating does this relay have?

It has 4PDT (4 Form C) contacts rated at 3A @ 250VAC, suitable for switching small motor contactor coils, pilot lights, or solenoid valves.
