Omron Panel Timer Relay, 4-Contact, DPDT, 125 V DC, 100-120 V AC, 0.1 min to 10 h Multifunction H3YN

Omron H3YN-21-B 100-120VAC Panel Timer Relay is a multifunction timer relay designed for industrial automation applications requiring precise and configurable time delays. Featuring a double-pole double-throw (DPDT) contact configuration with four contacts rated at 5A, the device provides reliable dual-circuit switching control in panel-mounted devices. It accepts AC supply voltages of 100 to 120 V as well as DC 125 V supply, enabling versatile installation in mixed voltage control systems.

The timer range is adjustable between 0.1 minutes up to 10 hours, providing broad flexibility to meet various process timing requirements. Push-in terminals facilitate quick and secure wiring without the need for tools, simplifying installation and maintenance operations. This compact relay measures 56.6 mm in width, 21.5 mm in length, and 28 mm in height, making it well suited for installation in compact control panels or retrofit projects.

Designed for operation in environmental temperatures from -10 °C to +55 °C, the H3YN series relay ensures dependable performance under typical industrial indoor conditions. The relay is rated for switching voltages up to 250 V AC and has mechanical and climatic protection rated to IP40 standards, which protect against dust ingress and mechanical contact risks.

The device complies with major international safety and interoperability standards including UL 508, EN 61812-1, Lloyd’s Register approvals, CE marking, China Compulsory Certification (CCC), and Canadian Standards Association CSA C22.2 No. 14, making it suitable for regulated industrial environments worldwide.

Common applications include stage sequencing in industrial automation panels, timed control of motors and solenoid valves, retrofit in existing control stations, process timing in automation machinery, and delayed interlocks in electrical distribution systems. Its multifunction timing capability allows use in varied sequential and time-dependent control tasks across industrial and manufacturing sectors.
