Its 4PDT (4 Form C) contact arrangement switches up to 3 A at 250 VAC, making it suitable for controlling multiple loads or signal paths from a single timing event — common in conveyor sequencing, pump alternation, or HVAC staging where one timer governs several contactors. ## Supply and mounting The coil is rated for 100 to 120 VAC, and the relay plugs into a socketable base. Timing is initiated by applying input voltage; the hand dial allows field adjustment without removing the relay from its socket, which saves time during commissioning or retooling.","metaTitle":"Omron H3Y-4 AC100-120 120S Time Delay Relay, 4PDT, 5-120 Sec","metaDescription":"Omron H3Y-4 AC100-120 120S time delay relay, 4PDT, 5-120 sec adjustable, 3A at 250VAC.
