Off-delay timer, DC coil, octal base
The Omron H3CR-HRL DC100-125 M is an off-delay timer relay from the H3CR-H series, meaning the timing cycle starts when the input voltage is removed — the load stays energized for the set delay after the control signal drops out. This is the function you want for sequenced shutdowns, post-lubrication run-down, or delayed venting after a stop command. Supply is 100–125 VDC, so it drops into a DC control bus at nominal 110 V or 125 V without an external dropping resistor. The DPDT (2 Form C) contacts are rated 5 A at 250 VAC — enough for pilot-duty solenoid valves, contactor coils, or indicator loads. Delay is adjustable from 0.05 minutes (3 seconds) to 12 minutes via the front-panel hand dial, which lets you set the timing without powering the unit. Termination is an 11-pin octal plug — mates with standard octal sockets (e.g. Omron PYF-11 or equivalent) for quick replacement without rewiring.
