Coil supply is 12VDC, so it pulls directly from a standard 12V control rail without an interposing relay; contact rating is 3A at 250VAC, which is enough to switch small contactor coils, solenoid valves, pilot lamps, or a fan/buzzer on a control panel — not a motor starter coil. ## Timing range and how it is set Delay range covers 0.1 second through 10 minutes on a single dial window, with the function mode and range selected through the front-face thumbwheel switches — the installer dials time and mode without a laptop or handheld programmer, which matters on a plant floor where the timer sits in a cabinet above eye level. Timing initiate is input voltage: power on the coil starts the delay. The plug-in termination into an 8-pin or matching socket means swap-out is pull-and-replace — no re-wiring — which is why the H3RN is the kind of part the MRO shelf carries as a critical spare. ## Sourcing posture for a mature but still active timer Lifecycle stage reads as mature and the product status is active — the H3RN has been in the Omron line long enough to be a known quantity on retrofit and MRO orders rather than a new-design choice. Specified into a panel BOM or stocked as a fast-mover critical spare: quoted to order through independent distribution with current pricing and availability confirmed at RFQ. No dealer-fresh stockholding claim; the part moves through the RFQ pipeline rather than the shelf.","metaTitle":"Omron H3RN-1 DC12 Timer, SPDT, 12VDC, 0.1s–10min","metaDescription":"Omron H3RN-1 DC12 multi-function timer relay, SPDT, 12VDC coil, 0.1 sec to 10 min range, 3A at 250VAC contact rating.
