Multi-function DPDT timer in the H3YN socket format
The H3YN-21 AC200-230 from Omron is a programmable multi-function timer with DPDT (2 Form C) mechanical relay outputs in the H3YN series, built around a plug-in socket body for DIN-rail or panel mounting. Timing runs from 0.1 minutes up to 10 hours with a hand-dial adjustment, and the relay contacts are rated 5A at 250VAC — enough for solenoid valves, contactor coils, and small motor loads in a control panel.
200-230VAC supply, input-voltage initiate
Operating supply is 200 to 230VAC and timing is initiated by the input voltage itself, which keeps the wiring simple — the timer starts when the supply is applied, with no separate trigger terminal needed. The 11-pin plug-in termination means the unit pulls out of its matching PYF or equivalent socket for fast field replacement, and the bulk package format suits both panel-build quantities and MRO spares.
