The Omron H3CR-A8EAC100240DC100D5 is a time delay relay — a panel-mounted timer that delays or intervals a signal in a control circuit. It accepts a universal supply of AC100-240V or DC100-125V, making it a drop-in for machines wired to either mains or a DC bus. The 'A8' suffix in the order code typically denotes an 8-pin octal-base configuration, which means it plugs into a standard socket rather than hard-wiring directly to the terminals — a swap-friendly detail when a timer fails on a 2am line-down call.
Deployment context
The octal-base form factor means this relay mounts into a panel via an 8-pin socket (sold separately), which simplifies replacement without rewiring. Typical deployment is inside a control cabinet where a timed delay is needed — conveyor start sequencing, pump alternation, or a delay-before-brake release on a motor drive. The universal supply range lets it run on either the AC control transformer or a DC power supply without a separate voltage module.
