The Omron H3Y-2 AC100-120 60S is a socketable, mechanical time delay relay from the H3Y series, offering both off-delay and on-delay functions with a hand-dial adjustable timing range of 2 to 60 seconds. It switches DPDT (2 Form C) contacts rated at 5A @ 250VAC, powered by a 100-120VAC supply via a plug-in termination style. Timing is initiated by input voltage, making it a straightforward drop-in for panel timing sequences where the load circuit and coil share the same AC supply.
The 5A @ 250VAC contact rating on DPDT (2 Form C) means each pole switches a resistive load up to 5 amps at line voltage — enough for pilot lights, contactor coils, or small solenoid valves in a control panel. The 2-60 second dial range covers common timing jobs like motor start sequencing, conveyor delay, or pump alternation. The socketable plug-in base (standard 8-pin octal) lets you swap the relay without disturbing panel wiring — useful for MRO spares or quick troubleshooting on a live cabinet.
