Omron H3CR-H8RL DC100-125 S is an off-delay timer relay from the H3CR-H series. It's an SPDT (1 Form C) mechanical relay, socketable on an 8-pin octal base. Time range is 0.05 to 12 seconds, set by a hand dial on the front. Coil is 100–125 VDC. Contacts are rated 5 A at 250 VAC — enough for pilot duty, small contactors, or signal switching in a panel. Timing is initiated by applying input voltage; when that voltage drops, the delay starts counting and the contacts transfer after the set time. That's the off-delay function: load stays powered during the delay, then drops. The octal pinout is the same as the classic Omron H3CR and many Eaton/Cutler-Hammer timers — if you're pulling a dead unit off a DIN-rail socket, this is the one that bolts straight in without rewiring.

Frequently asked questions
What is the closest pin-compatible alternative to H3CR-H8RL DC100-125 S?
The entire H3CR-H series shares the same 8-pin octal base and mechanical relay output. The key difference is function and time range: this one is off-delay, 0.05–12 sec. An on-delay variant like H3CR-H8L uses the same socket and coil voltage but starts timing when power is applied. If the function matches, any H3CR-H with the same coil voltage and SPDT contacts is a direct mechanical swap.
