Where it fits in the panel
The Omron H3YN-41 DC125 is a multi-function plug-in timer from the H3YN series, built around a mechanical 4PDT (4 Form C) relay with a 125 VDC coil — the kind of module that drops into a control panel socket to sequence blowers, lubrication pumps, or batch timers without a PLC slot dedicated to the job. Delay range spans 0.1 min to 10 hrs on a hand-dial adjust, so a single SKU covers short-interval lubrication cycles and long batching dwells without swapping the timer body.
Contact rating and socket mounting
Output contacts are rated 3 A at 250 VAC — enough for pilot-duty loads, solenoid coils, and small motor contactors, but the limiting factor is the 4PDT density per socket pin rather than the contact itself. Plug-in termination and socketable mounting mean field replacement is a pull-and-swap, not a rewire — useful on a line-down where the MRO shelf needs the timer back in service before the next shift change.
lists the part as Active, and the ledger's lifecycle stage reads mature — the H3YN platform has been in the field long enough that documentation, sockets, and replacement units are familiar to most panel builders.
