The Omron H5CN-XZNS AC100-240 is a socketable on-delay timer from the H5CN series, with a solid state relay output and a programmable delay range of 0.001 to 9.999 seconds. It's powered by 100-240 VAC and terminates via an 8-pin octal plug — the same footprint as a standard octal relay socket, so it swaps into an existing panel layout without rewiring the base.
The 0.001-9.999 second range is set via up/down digit keys on the front face — no screwdriver trim pot, no guesswork. That makes it repeatable across multiple units on a line, since the digital setting is exact rather than a percentage of a dial. Timing initiates on application of input voltage — standard on-delay behavior: apply power, the delay count starts, output switches at the end of the set time. The 8-pin octal socket (plug-in termination) means the timer body can be pulled and replaced in seconds without disturbing panel wiring, which is the main reason this form factor persists in industrial controls.
