H3DK-M2 is a solid-state, DIN-rail-mounted multi-mode timer relay from OMRON designed for versatile automation control. It provides eight timing modes—ON-delay, interval, flicker ON start, and others—with a wide selectable time range from 0.1s to 1,200h. The unit operates on 24 to 240 VAC/DC and accepts voltage input start signals for flexible application in control panels and machine automation. Its DPDT relay output provides reliable time-limit and instantaneous contact switching, while terminal block connections simplify wiring and ensure secure installation in compact enclosures.
