The Omron H3Y-2 AC100-120 5S is a socketable electromechanical time delay relay with a DPDT (2 Form C) output. It covers a 0.2-second to 5-second delay range, adjustable via a front-panel hand dial. The relay supports both off-delay and on-delay timing modes, initiated by the input voltage (100–120 VAC). The 5 A at 250 VAC contact rating handles typical control loads — solenoids, contactor coils, pilot lights — in a panel. The plug-in termination style mates with standard 8-pin octal sockets, so swapping a failed unit on a live line takes seconds. Mounting is socketable, not DIN-rail direct; the socket itself occupies the DIN rail or panel footprint.

Product details
Frequently asked questions
What is H3Y-2 AC100-120 5S's listed series (H3Y) on this component line?
The series is Omron H3Y, a family of socketable electromechanical time delay relays with DPDT contacts.
What is H3Y-2 AC100-120 5S's listed circuit (DPDT (2 Form C)) on this component line?
The relay has a DPDT (2 Form C) output — two independent form-C contact sets, each with one normally-open and one normally-closed pole. This gives you two isolated switch channels per relay.
