Timer defined: DPDT mechanical relay, adjustable 0.2–5 s
Time-delay relay — electromechanical device that opens or closes its output contacts a set time after the coil is energized or de-energized. The H3Y-2 AC200-230 5S is Omron's H3Y-series entry in this class, built around a DPDT mechanical relay contact set (two Form C poles) and housed for an 8-pin plug-in socket, with a hand-dial on the face to set the delay.
Off-delay and on-delay, dial-set from 0.2 s to 5 s
The unit operates in either off-delay or on-delay mode — the timing sequence (start counting on energize vs. on release) is selected at wiring — with the delay hand-dialed across a 0.2 s to 5 s window. Timing initiation is triggered by the input voltage itself, so no separate trigger terminal is needed.
5 A contact rating at 250 VAC — pick the right socket and load
Output contacts are rated 5 A at 250 VAC, which is the practical ceiling for the DPDT mechanical relay inside the housing — sized for control-panel loads like contactor coils, solenoid valves, and small motor starters rather than for direct switching of heaters or larger motors. Because the relay is socketable on an 8-pin octal or matching pin-style base, replacing a failed unit on a live panel is a pull-and-plug swap once the supply is isolated.
200–230 VAC supply, mature active part
Coil supply is specified at 200 to 230 VAC, matching European and Asian industrial control voltages. Omron lists the part as active in production with a mature lifecycle stage — long-running series with stable sourcing, not a phase-out.
