Off-delay timing in a DPDT octal package
The Omron H3CR-H8L DC100-125 S is an off-delay timer built around a DPDT (2 Form C) mechanical relay, so a single timer can switch two independent loads when the initiating voltage is removed. Timing is adjustable from 0.05 sec to 12 sec on a hand dial, initiated by the input voltage itself — the relay holds its contacts through the delay after the trigger drops, which is the classic off-delay signature used to keep fans, alarms, or sequential logic running after a machine stop.
Coil supply, contacts, and panel-side wiring
Supply is 100 to 125 VDC, which lines the timer up with common 110 VDC control rails in process and instrumentation cabinets rather than the 24 VDC or 100–240 VAC variants that share the same socket footprint. Contacts are rated 5 A at 250 VAC, giving the timer enough headroom to drive small motor contactors, solenoid valves, and indicator loads directly without an interposing relay on most panel builds. Termination is an 8-pin octal plug-in, socketable mount, so the timer drops into a standard panel socket and can be swapped in seconds without disturbing the field wiring — useful when a control relay fails and the line is down.
Lifecycle posture and sourcing
Lifecycle is recorded as active with a mature product stage, so the H3CR-H8L DC100-125 S remains a current Omron catalog line rather than a discontinued or NRND position.
