What the H3YN-2-B brings to the panel
The Omron H3YN-2-B AC100-120 is a multi-function plug-in timer from the H3YN series, built around a mechanical DPDT relay with 5 A contact rating at 250 VAC — enough headroom for small solenoid, indicator, or interposing relay loads in a control cabinet, not for direct motor switching. Powered straight from a 100 to 120 VAC control supply, it slots into a standard 8-pin or 11-pin socket and times from 0.1 seconds up to 10 minutes on a hand-dial setting, which is the typical reach for sequenced start delays, star-delta transition timing, or purge cycles on packaging and process lines.
Sourcing and lifecycle posture
records the part as Active within Omron's mature H3YN series, with no official successor on the ledger — the BOM position stays on the original order code and the stocking strategy can be planned as a long-running standard rather than a last-time-buy. On the MRO shelf this is the kind of fast-mover that earns a kept-on-hand min/max slot: widely deployed, plug-in replaceable, and held against the lead time the panel sees when one fails mid-cycle.
