The Omron H5CN-XBNM DC24 is an on-delay time relay from the H5CN series, set via up/down digit keys for a delay range of 0.001 to 99.99 seconds. It switches a single SPDT (1 Form C) mechanical relay contact rated at 3 A at 250 VAC. Supply voltage spans 12 to 48 VDC, and the timing initiates on application of input voltage. The octal 11-pin (plug-in) termination style means it mates with standard industrial relay sockets — common in control panels where a failed timer gets swapped in seconds without rewiring. The up/down digit keys allow precise setpoint entry, unlike trim-pot-adjusted timers that drift over temperature.
The H5CN series is a mature, broadly deployed line — not a niche or end-of-life product. For BOM freeze or PCN watch, this part is a stable selection.
