What the coil and contact set actually cover
The H3YN-41 DC24 sits in Omron's H3YN series as a multi-function programmable timer, taking a 24 VDC supply on a plug-in base and switching a 4PDT (4 Form C) mechanical relay output. The four-pole Form C arrangement gives the installer two NO and two NC contact sets from one timing block — useful where a single timer has to release one load and pick up another after a programmed interval. Output contacts are rated 3 A at 250 VAC — the limit that matters when the timer drives a small contactor coil, a solenoid, or an indicator, not a motor contactor. For higher inrush or motor loads, the load should be switched through an interposing relay sized for the duty.
Timing range, adjustment, and how it starts
The delay window runs from 0.1 minutes to 10 hours, selected on a hand-dial face — the range covers a slow sequencing timer on a conveyor staging circuit as readily as a short process-interval timer on a wash cycle. Timing starts on applied input voltage, which keeps the wiring to a single start lead rather than a separate trigger terminal — the trade-off is that power loss resets the timer and the cycle restarts on re-energization. Multi-function programmability means one stock code covers on-delay, off-delay, interval, and cycle modes without committing the panel to four separate timer SKUs.
Socket-mounting in the panel
The relay drops onto a standard 8- or 11-pin octal-style socket — the socketable mount is what lets a worn timer be swapped in seconds without disturbing the field wiring, and it is the reason this part tends to ride the shelf as a critical spare rather than a build-only line item. Bulk packaging confirms the part is aimed at panel-build quantities rather than single-piece retail.
Lifecycle and supply posture
Omron lists the part as Active, while the catalog flags the series as mature — meaning the H3YN line continues in production but is not the latest generation Omron is pushing. For an MRO buyer this is a comfortable posture: the part is still factory-supported, spares will keep flowing, and the older series positioning suggests pricing has settled.
