The Omron H3CR-H8RL DC100-125 M is a socket-mount time delay relay in the H3CR-H series, configured for Off-Delay timing. It operates on a 100–125 VDC control supply and switches a single SPDT (Form C) output rated 5 A at 250 VAC. The delay is adjustable via a front-panel hand dial from 0.05 to 12 minutes, initiated by application of the input voltage.
The 5 A / 250 VAC SPDT contact rating covers pilot-duty loads—contactors, solenoid valves, indicator lamps—common in control panels. The Off-Delay function means the relay picks up immediately when power is applied and drops out after the set time once power is removed; useful for sequenced shutdowns or post-run purge cycles. The 100–125 VDC coil is a non-standard voltage for many panels, so confirm your DC supply rail matches before specifying. Termination is via an 8-pin octal plug (Plug In, 8 Pin (Octal)), which mates with standard octal relay sockets. This makes replacement straightforward without rewiring—pull the old relay, plug in the new one. The socketable form factor also allows the relay to be swapped for a different timing range or function without touching panel wiring.
