The Omron H3DK-HCS AC100-120V is an off-delay time relay from the H3DK-H series, designed for timing control in industrial panels. It switches a SPDT (1 Form C) contact rated at 5A @ 250VAC, sufficient for pilot duty, signal lamps, or small solenoid loads. The delay range is adjustable from 0.1 to 12 seconds via a screwdriver slot, initiated by application of the supply voltage. Mounts on DIN rail with screw terminals, fitting standard panel layouts. The 100–120VAC supply means it drops into existing control transformer circuits without a separate DC power supply.
