Series, coil, and contact rating
The Omron H3YN-41 AC24 sits in the H3YN programmable timer family and runs off a 24VAC supply, making it a drop-in for control transformers fed from 120/230 VAC panels without needing an interposing DC source. Its 4PDT (4 Form C) contact set is rated 3A at 250VAC — a contact ceiling sized for switching pilot devices, solenoid coils, small contactors, and indicator loads rather than motor power.
Timing range and adjustment method
Timing covers 0.1 Min ~ 10 Hrs across the multi-function modes, with hand-dial adjustment under the flap so the field tech sets the time without a programming pendant. Initiate is by input voltage, so the coil itself both powers the logic and acts as the start signal — common for on-delay and interval functions in machinery sequencing. The output is a mechanical relay, not a solid-state switch — meaning it can switch AC and DC contact loads, but the 3A contact ceiling must be respected; expect a relay life derating when switching inductive loads like solenoids or small motor contactors well below the contact rating.
Termination is plug-in via an 8-pin or 11-pin socket, and the unit is socketable so it swaps out of the panel in seconds — important for the field-service playbook when a timer fails on a line. Bulk packaging is the contract-manufacturer and panel-builder norm; expect a matched PYF-style socket to be ordered separately and not shipped with the timer body.
