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.","metaTitle":"Omron H3YN-4 DC125 Timer, 4PDT, 125VDC, 10 min","metaDescription":"Omron H3YN-4 DC125 multi-function plug-in timer, 4PDT contacts rated 3A at 250VAC, 0.1 sec to 10 min range, 125 VDC coil.

For higher-current loads, stage a contactor downstream."},{"question":"What timing modes does H3YN-4 DC125 cover?","answer":"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.
