Off-delay DPDT timer, 11-pin octal, 24 VAC/DC
Omron H3CR-HRL AC/DC24 M sits in the H3CR-H series as an off-delay timer with a DPDT (2 Form C) mechanical relay output, wired in on an 11-pin octal plug-in base at 24 VAC/DC supply — the standard footprint for DIN-rail or panel-mount timing relays in control cabinets where the off-delay sequence drives a downstream contactor or alarm after a run signal drops. The contact block is rated 5 A at 250 VAC, which governs the real switching envelope: resistive and lightly inductive loads fit comfortably, while any motor starter coil or solenoid pulling more than 5 A has to be driven through an interposing relay rather than directly off the timer contacts.
Timing range and field adjustment
Delay range is 0.05 min to 12 min — three seconds up to twelve minutes — set via a hand dial on the front face, so the timing is adjustable in the field without a programmer or handheld. Input voltage initiates the timing, meaning the off-delay starts when the control voltage is removed. That input-voltage trigger method matters on retrofits: the timer expects a maintained control signal that drops to release the timing, not a momentary pulse — wire it after the contactor seal-in auxiliary, not in parallel with the start pushbutton.
