Form factor and what it does
The H3Y-4 AC200-230 5S is the H3Y-series socketable timer relay with a 4PDT (4 Form C) contact set, built around a mechanical relay rather than a solid-state output — four independent form-C poles let one timer drive multiple loads (e.g., a control interlock plus a status indicator) from a single timing event. Timing runs from 0.2 s to 5 s on a hand-dial adjustment and can be configured as either off-delay or on-delay depending on wiring, so the same part covers both 'keep running after the trigger drops' and 'delay before energising' sequences in a packaging or process line.
Coil, contacts, and wiring
Coil supply is 200–230 VAC, accepting the standard control-transformer secondary without a step-down stage; timing initiates from the input voltage itself, so no separate trigger terminal is needed. Contact rating is 3 A at 250 VAC — sized for auxiliary loads such as contactors, solenoid valves, and indicator lamps rather than direct motor switching; the part terminates via a plug-in socket, so the timer body lifts out for bench service without disturbing the panel wiring.
Lifecycle and supply
Lifecycle is recorded as mature and the product is listed as active — long-running H3Y-series supply, not a last-time-buy situation.
