Omron DIN Rail Surface Mount Timer Relay 4PDT, 4-Contact, 24V AC Supply, 125V DC Switching, Time Range 2-60 H3Y-4 AC24 60S

Omron H3Y-4 AC24 60S DIN Rail Surface Mount Timer Relay delivers reliable and adjustable time-delay control essential for industrial automation systems and electrical panels. This timer relay supports an adjustable time range from 2 to 60 seconds, allowing precise control of circuit switching after a preset delay. Equipped with four 4PDT changeover contacts, it enables simultaneous control of multiple output circuits for complex sequencing tasks.

Powered by a 24V AC supply with the capability to switch DC voltages up to 125V and contact current up to 5A, this relay suits moderate load control requirements within manufacturing, HVAC, and material handling systems. The plug-in terminal design facilitates rapid installation and maintenance by allowing easy withdrawal and replacement on standard DIN rail mounting systems without rewiring the panel.

Engineered for rugged industrial environments, the relay tolerates operating temperatures from −10 °C to 50 °C and features an IP40 enclosure rating ensuring protection from solid foreign objects. Compliance with recognized standards such as IEC 60664-1, UL 508, CE, and EN 61812-1 confirms its quality and safety credentials for diverse applications.

Common applications include staging of motor start sequences in plant control panels, delay functions for conveyor systems and material handling equipment, timed controls in HVAC and building management circuits, and interlock delay mechanisms in safety and machinery control systems.

Equipped with four 4PDT changeover contacts to enable multi-circuit sequencing. Operates with a 24V AC supply and switches up to 125V DC at 5A contact current. Mounts securely on DIN rails with plug-in terminals for rapid installation and service.

Features ON Delay mode suitable for delay and sequencing functions in various control systems. Designed for operation in temperatures ranging from −10 °C to 50 °C with IP40 protection rating. Complies with international standards including IEC 60664-1, UL 508, and EN 61812-1 for reliable performance.

Ideal for motor start sequences, conveyor delays, HVAC controls, and safety interlocks. Explore more Timer Relays and Omron automation products at EnvMart for your industrial and electrical control needs.
