Product Description
The Omron H3Y-2- is a miniature solid-state, single-function ON-delay timer relay designed for industrial control panels and machine automation. It features a large transparent time-setting knob for analog adjustment, two-pole double-throw (DPDT) output contacts rated at 5A at 250VAC, and pin configuration compatible with Omron's MY-series power relay sockets. The H3Y-2- is available in multiple supply voltage variants (12VDC to 230VAC) and multiple timing range options, making it suitable for motor starter sequencing, safety interlock delays, conveyor belt synchronization, and HVAC fan run-on applications.
