Product details

Form-C contact set and what it switches

Omron H3YN-4 DC125 ships as a mechanical-relay, 4PDT (4 Form C) timer with contacts rated 3 A at 250 VAC — meaning a single timer can land four independent Form-C changeovers in one socket footprint, which keeps wiring tight when a sequence needs more than one dry contact per stage. The 125 VDC supply rail is non-standard for a panel timer — most timer sockets feed 24 VDC or 110–240 VAC; on a 125 VDC coil you want to confirm the socket and the upstream PSU rating before the BOM freezes.

Multi-function timing range

Function is programmable (multi-function) with a timing range of 0.1 sec to 10 min, initiated by input voltage and adjusted via a hand dial on the face — so one SKU covers on-delay, off-delay, interval, and the other common modes a panel builder needs without swapping the relay. Termination is plug-in to an 11-pin or blade socket, so a failed timer pulls straight out and a spare drops in — that socketable mounting is the field-service advantage over PCB-mount timers that require a desolder step.

Lifecycle and sourcing for H3YN-4 DC125

Sourcing posture: quoted to order through independent distribution against the BOM quantity — no price or stock figure is on this page, and availability is confirmed at RFQ time.

Frequently asked questions

What is the contact rating on H3YN-4 DC125?

The mechanical-relay contacts are rated 3 A at 250 VAC across the full 4PDT (4 Form C) set, so the timer carries standard control-circuit loads — pilot relays, solenoid valves, indicator lamps — rather than power-switching duty. For higher-current loads, stage a contactor downstream.

What timing modes does H3YN-4 DC125 cover?

It is a multi-function timer covering the common modes in the H3YN family — on-delay, off-delay, interval, and related sequences — across a 0.1 sec to 10 min range set by the hand dial. The initiate source is input voltage, so the timing cycle starts when the coil sees 125 VDC.
