What H3YN-4 AC200-230 actually does on the panel
The Omron H3YN-4 AC200-230 is a multi-function, plug-in timer from the H3YN series, built around a 4PDT (4 Form C) mechanical relay that switches four independent poles from a single timed event so a control designer can fan one timing signal out to several loads without paralleling contactors. Its 200-230VAC supply window lines up with the standard control-power rails found in industrial panels, and timing is initiated directly from the input voltage, so no separate trigger wiring is needed at the socket.
Timing range and contact rating in plain terms
The delay span runs from 0.1 Sec to 10 Min and is set with a hand dial on the front face, so the same unit covers sub-second nuisance delays up through multi-minute sequencing without swapping modules. Each of the four Form C contacts is rated 3 A at 250VAC, which is the right size for driving small solenoid valves, interposing relays, and indicator lamps rather than direct motor loads; the relay type is mechanical, so the switching isolation is real galvanic isolation through the contacts, not a solid-state output. Mounting is socketable with a plug-in termination style, supplied in bulk packaging for panel-build kitting: the timer body drops into a standard 11-pin or 14-pin H3YN socket so a service tech can swap a suspect timer out without disturbing the field wiring.
Lifecycle posture and replacement context
The H3YN-4 AC200-230 is listed as Active by the manufacturer, so it remains in normal production rather than being routed through last-time-buy or surplus channels; the field flags it as a mature series, which on Omron's portfolio typically means long-term availability rather than imminent phase-out, but the spare-parts BOM should still be cross-checked against current PCN bulletins before a long-horizon build.
