5 A SPDT output, 12 sec off-delay window
The H3CR-H8RL AC100-120 S is an Omron H3CR-H series off-delay timer with a single SPDT (1 Form C) contact rated 5 A at 250 VAC — sufficient for directly switching small solenoids, contactors, and indicator loads on a control panel without an interposing relay. Timing runs from 0.05 sec to 12 sec on a hand-dial adjustment, initiated by the input voltage — the standard pattern for fan rundown, coil hold-off, and post-shutdown dwell sequences on packaging and process skids. It plugs into a standard 8-pin octal socket on 100–120 VAC supply, so a swap on a live panel is a pull-and-replace rather than a rewire.
Lifecycle — mature and still active
The device carries an active product status; the series is listed as mature, meaning incremental rather than rolling new revisions — the H3CR-H footprint has been the de-facto 8-pin off-delay choice for control panels for years, and the existing socket base stays valid through any replenishment order.
