The Omron H5CX-A11D-N DC12-24/AC24 is a programmable multi-function timer relay from the H5CX series, built around an SPDT (1 Form C) mechanical relay output rated for 5 A at 250 VAC. Its timing range spans 0.001 seconds to 9999 hours, set via up/down digit keys — no DIP switches or trim pots to mis-calibrate. Supply voltage accepts 24 VAC or 12–24 VDC, making it straightforward to drop into existing control panels with mixed AC/DC control power.
Socket-mounts via an 11-pin octal base (sold separately) — standard footprint that matches existing panel cutouts and pre-wired sockets. The termination style is plug-in, so swapping a failed unit takes seconds without disturbing wiring. Timing initiates on input voltage or an external trigger signal, giving flexibility for both power-on delay and signal-edge start applications.
