The Omron H5CXA11NOMI is a multifunction time relay that covers a wide timing span from 1 ms to 9999 h across 10 selectable time ranges, making it suitable for delay-on, delay-off, interval, and one-shot applications in control panels. Its 11-pin socket termination lets you swap the unit without rewiring — handy when you're chasing a timing fault on site and the old relay is already socketed. The IP66 rating means it can handle washdown environments or outdoor enclosures where dust and water jets are a concern — not just a dry cabinet timer.
Switching is rated at 5 A for both AC (250 V) and DC (30 V) circuits, with a DC power limit of 150 W — so it can handle small contactors, pilot lights, and solenoid valves directly, but not motor loads above that threshold. The single changeover contact (1CO,) gives you one form-C relay output; if your circuit needs two isolated timing outputs or a separate instantaneous contact, you'll need a different model or an interposing relay. Operating voltage range is 100 to 240 VAC, so it works across common line voltages without a tap change — just land the supply on the correct socket pins per the wiring diagram.
Where you'll use it
Drops into an 11-pin round relay socket — common in panel builds for timers, and the socket itself mounts on DIN rail or panel. The IP66 face means it can live on the outside of a washdown-rated enclosure without a separate cover. Multifunction mode selection is done via DIP switches on the front, so you can reconfigure the timing function on the fly without pulling the unit — useful when the sequence logic changes during commissioning.
