Where the H3CR-A 8-pin timer drops into the panel
The Omron H3CRA8AC100240DC100125OMI is a multi-mode plug-in timer from the H3CR-A series, built around an 8-pin octal socket with a panel-side sealing of IP40. Five selectable timing functions on a single base — Flicker ON Start, Interval, ON-Delay, and One Shot Output across 5 programmable modes — let one stock SKU cover the start-delay, pulse-train, and one-shot jobs that show up across conveyor, packaging, and pump control panels without rewiring the socket. Operating voltage spans 100 V to 240 V, so the same timer body drops onto 120 VAC and 230 VAC control transformers without a separate variant.
Timing range and what the dial actually reaches
Time setting runs from 0.05 s minimum to 300 h maximum — roughly five orders of magnitude on one time base, which means a single H3CR-A module handles both the sub-second brake-release pulse and the multi-day curing interval that a maintenance spare would otherwise stock as two separate timers. Five selectable timing functions cover the workhorse modes a panel builder cycles through: ON-Delay for staggered motor starts, Interval for fixed-width output pulses, Flicker ON-Start for asymmetric repetitive cycling, and One Shot for triggered single-shot actuation.
Output contacts — 5 A DPDT in a small footprint
Two changeover contacts — 2CO / DPDT — switch 5 A at 250 VAC or 30 VDC. That is a switching ceiling of 1.25 kVA on the AC side and 150 W on the DC side, enough to drive contactor coils, solenoid valves, and indicator lamps directly without an interposing relay in most control schemes. The 5 A / 250 VAC rating is the contact-limit figure; when the timer is sequencing a larger contactor, the timer output drives the coil and the contactor carries the motor — keep the inrush within the timer contact ceiling rather than sizing for steady-state only.
Mature line — sourcing posture for an H3CR-A spare
That positioning typically means ongoing manufacture against order rather than promotional new-product stocking, and it is the right context for a buyer: the part is still in the catalog, but availability flows through independent distribution rather than factory-direct just-in-time. For a panel-build BOM or a maintenance spare, the practical move is to quote the exact order code against an RFQ — the 8-pin socket form factor keeps it swappable with any H3CR-A timer that has been sitting in the same panel footprint for years.
