The Omron H3DK-HDS AC200-240V is an off-delay timer relay from the H3DK-H series, meaning the timing cycle starts when the input voltage is removed — the load stays energized for the set delay after the control signal drops. That makes it the right choice for sequenced shutdowns, post-run cooling fans, or any circuit where equipment needs to coast down before the contact opens. Rated 5 A at 250 VAC (SPDT Form C), it switches resistive or lightly inductive loads within that envelope. The delay range spans 0.1 to 12 seconds, set via a screwdriver slot on the front face — no DIP switches, no programming tool. Supply is 200-240 VAC, so it lands directly on a standard European or Asian line voltage without a separate control transformer. DIN rail mounting and screw terminals keep panel integration straightforward — snaps onto the rail, lands the wires, and it's live.

Frequently asked questions
What is the delay range and how is it adjusted?
The delay range is 0.1 to 12 seconds, adjusted by a screwdriver slot on the front of the relay. No DIP switches or software required.
What is the contact rating on the H3DK-HDS AC200-240V?
The SPDT (1 Form C) contacts are rated 5 A at 250 VAC. That covers resistive and light inductive loads within that envelope.
Where can I buy the H3DK-HDS AC200-240V?
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
