Omron H3DK-HDL AC200-240V Off-Delay Timer, SPDT 5A, 1-120 Se

The Omron H3DK-HDL AC200-240V is an off-delay timer relay from the H3DK-H series, wired for SPDT (1 Form C) switching. It's a mechanical relay, so the contact closure is positive and the dropout is clean — no solid-state leakage to chase. The delay range spans 1 to 120 seconds, set via a screwdriver slot on the front face; timing is initiated by applying the input voltage, which means the output relay picks up immediately and drops out after the set delay once the supply is removed. That makes it a straight off-delay for sequencing a motor stop or a valve close after a power-loss signal. The contacts are rated 5 A at 250 VAC, which covers most pilot-duty and small motor loads in a control panel. Supply is 200 to 240 VAC, so it lands directly on a standard 230 V control transformer without a separate DC supply. Mounting is DIN rail, termination is screw terminal — no special tooling needed for a panel build.
