Product details

The Omron H3Y-4 DC24 1S is a mechanical time delay relay from the H3Y series, offering both Off-Delay and On-Delay functions selectable via the hand dial. The delay range is 0.1 Sec to 1 Sec, initiated by input voltage. Contact configuration is 4PDT (4 Form C) rated at 3A @ 250VAC, sufficient for switching small motor starters, contactor coils, or pilot lights in a control panel. Supply is 24VDC, termination is plug-in to an 8- or 11-pin socket (socketable mounting).

Socketable plug-in termination means the relay body mounts to a standard 8- or 11-pin octal-style socket (not included). The hand dial for timing adjustment is accessible on the relay face, allowing field changes without removing the relay from the socket. The 4PDT output provides four independent Form C contacts, each rated 3A @ 250VAC — adequate for pilot-duty control circuits in a panel.

Frequently asked questions

Who supplies H3Y-4 DC24 1S and how is it quoted for volume purchases?

This part is sourced through independent industrial automation distribution. For volume procurement, submit an RFQ; availability and current pricing are confirmed at quote time.

What is H3Y-4 DC24 1S's listed series and circuit?

The series is H3Y. The circuit is 4PDT (4 Form C), meaning four independent changeover contact sets.

What is the delay range and adjustment method?

The delay range is 0.1 Sec to 1 Sec, adjustable via a hand dial on the relay face. Timing is initiated by applying the input voltage.
