Omron Solid State Timer DIN Rail, DPDT, 4-Contact, 125 V DC / 24 V AC, Multifunction H3YN

The Omron H3YN-21-B DC24 solid state timer is engineered for advanced automation, control panel, and industrial sequencing tasks. This timer integrates seamlessly onto DIN rails and allows precise programmable delay functions across a broad range from 0.1 minutes to 10 hours. Its DPDT, four-contact output configuration offers independent switching paths, making it ideal for applications where multiple outputs must be actuated after a defined period.

Designed for versatility, the timer accepts both 24 V AC and 125 V DC supply voltages. This wide compatibility enables integration in electrical panels with varied power regimes. Its compact footprint (width: 56.6 mm, height: 28 mm, length: 21.5 mm) ensures efficient use of panel space, supporting dense layouts in machine and control installations.

Multifunction timer modes allow custom delay, sequencing, and interlock operations for manufacturing lines, conveyor systems, or process control. With a maximum switching voltage of 250 V AC and a contact current rating of 5A, it fits many control circuits - ranging from industrial lighting to PLC auxiliary routines. Push-in terminals provide rapid wiring and reliable connection, reducing installation and service times.

Rated with IP40 protection, the H3YN-21-B DC24 timer is suitable for enclosed panels and plant automation. It operates reliably from -10°C to 55°C, adapting to typical indoor environments in factories, warehouses, and commercial automation. High-grade standards - UL 508, CSA C22.2 No. 14, EN 61812-1, IEC 60664-1, CCC, and Lloyds - ensure compliance with industrial safety and electrical requirements.

Use cases include conveyor motor sequencing, machine cycle delays, staged lighting, safety interlock delay operations, and integration with PLCs for timing or fault-reset tasks. Its robust design enables efficient and reliable operation across varied industrial, laboratory, and commercial automation applications.

Time range 0.1 min - 10 h for broad control flexibility. DPDT output, four-contact design for complex processes. Mounts on DIN rail; compact structure aids tight panel setups. Push-in terminal blocks streamline installation and maintenance.
