Omron DIN Rail Timer Relay 4-Contact, 100 - 120V AC, 125V DC, 0.2 - 5 min ON Delay, 4PDT, IP40 H3Y-4 100-120VAC 5M

The Omron H3Y-4 100-120VAC 5M timer relay is an industrial-grade component designed for use in control panels and automation systems requiring reliable time-delay switching. Featuring a compact, DIN rail mountable body and plug-in terminals, it is engineered to meet the requirements of panel builders and process control professionals. The relay offers a selectable ON delay function ranging from 0.2 to 5 minutes, making it ideal for timing, sequencing, and intermittent control tasks.

This relay supports both AC (100 - 120V) and DC (125V) input supply. Its four-pole double throw (4PDT) contact configuration allows simultaneous switching of four independent circuits, enhancing flexibility for machinery and process line integration. With a contact current rating of 3A, it efficiently handles moderate loads such as motors, actuators, lamps, and heaters in industrial setups.

Installation is simplified by the DIN rail mounting standard and plug-in terminal style, which streamlines panel assembly and retrofit applications. The device is protected by an IP40 enclosure rating, ensuring reliability in indoor panels and electrical enclosures where dust protection is critical, though it is not intended for wet environments.

Designed to operate from -10°C to 50°C, the relay performs dependably across typical industrial temperature ranges. Application scenarios include conveyor timing, packaging machine sequencing, test rigs, production lines, and heater/lamp control circuits. Its precise delay range enables repeatable, reliable control for complex logic or process requirements.

Built to international standards and approvals including EN 61812-1, IEC 60664-1, UL 508, CSA C22.2 No. 14, and others, the relay integrates seamlessly into panels compliant with global industrial control norms.

Provides controlled switching for automation panels and machines. Supports 0.2 to 5 min ON delay for short-duration cycle control. 4PDT contact configuration allows simultaneous multi-circuit switching. Compatible with both AC (100 - 120V) and DC (125V) supplies.

Plug-in/DIN rail mounting for fast installation and replacement. Suitable for sequencing, production line timing, and industrial process control.

Industrial professionals can use this relay for designing and maintaining manufacturing, test, and automation systems, with confidence that the product meets high standards of reliability and interoperability.
