Form-fit on the DIN rail
The Omron H3YN-4 DC100-110 is a plug-in, socketable timer relay from the H3YN series with a 4PDT (4 Form C) contact set, so four independent circuits can be timed from a single device — useful where a sequence needs more than one dry-contact output without stacking auxiliary relays. Supply is 100 ~ 110VDC and the unit terminates via 11-pin plug-in octal-style base, which keeps replacement a pull-and-swap on the socket rather than a re-wire.
Timing range and contact duty
Delay time spans 0.1 Sec ~ 10 Min across the dial, with timing initiated by input voltage and adjusted via the hand dial — the multi-function programmable mode means on-delay, interval, cycle, and other standard patterns are selected by the front-face switch rather than buying separate SKU variants. Contact rating is 3A @ 250VAC on a mechanical relay — adequate for control-circuit pilot duty to contactors, solenoid valves, and indicator loads, but the 3A ceiling means it will not drive a motor contactor coil bank directly on heavy inductive loads; stage through an interposing relay where the inrush is significant.
