It runs on a 48 VDC supply and accepts a hand-dial timing adjustment across 0.1 s to 10 min, with timing initiated by the input voltage. Output contacts are rated 3 A at 250 VAC — enough for pilot-duty switching of contactors, solenoid valves, and indicator loads in a control panel, but not for direct motor switching. ## Why buyers specify this H3YN variant The 4PDT (4 Form C) format gives four independent switched poles in one timer — useful when a sequence needs to drive more than one load (e.g. a contactor coil plus an indicator plus an alarm branch) without stacking auxiliary relays. The plug-in socketable termination lets the timer be pulled and replaced without disturbing the panel wiring — a real advantage in line-down service on a process skid. ## Lifecycle and sourcing for H3YN-4 DC48 Omron lists the H3YN-4 DC48 as active in the mature phase of its lifecycle, so supply through authorised channels remains open and the part is not on a last-time-buy clock. For procurement, H3YN-4 DC48 is specified into the BOM by the 48 VDC coil and 4PDT contact set; quotes against production quantities confirm lead time and unit price at RFQ through independent industrial distribution.","metaTitle":"Omron H3YN-4 DC48 Timer Relay, 4PDT, 48VDC, 10 Min","metaDescription":"Omron H3YN-4 DC48 multi-function timer relay, 4PDT, 0.1 s–10 min, 48 VDC coil, 3 A at 250 VAC.
