Availability and pricing are confirmed at RFQ — quantities are lot-specific and not held as standing stock. Supply voltage is 24–240 VAC or 12–240 VDC — covers most common control voltages in industrial panels without needing a separate power supply module. The wide-range input means it works on both 24 VDC PLC outputs and 120/240 VAC control transformers. Delay time spans 0.1 seconds to 9990 hours, set via thumbwheel switches on the front face. The multi-function programmable logic lets you select on-delay, off-delay, interval, or one-shot timing modes — one relay covers multiple timing jobs in a panel. Contact rating is 3 A at 250 VAC — sufficient for pilot-duty loads like contactor coils, solenoid valves, or indicator lamps. The SPDT (Form C) output gives both a normally-open and normally-closed set of contacts, so you can wire either the energized or de-energized state as the timed action. Mounts via an octal 11-pin plug-in base — the same footprint used across the H3CA family and many competitive timers. If your panel already has an 11-pin octal socket wired, this relay drops in without rewiring the base.","metaTitle":"Omron H3CA-A-306 Time Delay Relay, 0.1s-9990h, SPDT, 3A","metaDescription":"Omron H3CA-A-306 programmable time delay relay, SPDT 3A @ 250VAC, 24-240VAC/12-240VDC supply.
