It covers both Off-Delay and On-Delay in a single timer block, with a 0.5 min to 10 min adjustable range set by a hand dial on the face and initiated by the supply voltage on the input terminals, which simplifies wiring — no separate trigger terminal is needed. ## Coil, contacts, and wiring envelope The coil is rated 100 to 120VAC, which is the standard North-American/Japanese control-transformer secondary, so it drops straight onto a 120 V control bus without an interposing relay. Each of the four contact poles is rated 3A at 250VAC — the limiting factor for driving small contactors, solenoid valves, indicator lamps, or a PLC discrete input directly from the timed output, with no additional relay required on the load side. The unit is a mechanical-relay design in a socketable plug-in package, so field replacement is a matter of pulling the old cube and seating a fresh one in the same octal-style socket — no rewiring needed. ## Sourcing posture for the H3Y-4 Stock and lead-time are confirmed at quote time against an RFQ; the order is specified into the BOM and sourced through independent distribution with full manufacturer traceability.","metaTitle":"Omron H3Y-4 AC100-120 10M Timer, 4PDT, 10 Min","metaDescription":"Omron H3Y-4 AC100-120 10M electronic timer, 4PDT (4 Form C), 0.5–10 min off/on-delay, 100–120VAC coil, 3A @ 250VAC contacts.
