Omron H3YN Series Timer Relay, 4-Contact, 100 to 120 V ac 100/120 V ac, 0.1 to 600 s, Multifunction-Function, DPDT

This timer relay provides adjustable timing control for automated systems and control panels, designed to be installed via a plug-in Terminal arrangement. It operates from an AC supply within the 100/120V range and offers multiple timing functions for sequential or delayed control tasks. The device is intended for industrial electrical environments where compact, multifunction timing is required.

• DPDT contact set delivers changeover switching for dual circuits
• Four-contact design permits independent control of two loads
• Time range adjustable from 0.1 to 600 s allows fine timing resolution
• Rated for 100/120V AC supply compatibility with common mains
• Multifunction capability supports several timing modes in one unit
• IP40 enclosure rating suitable for protected indoor panels

• Suitable for sequence timing in automation control cabinets
• Ideal for delayed start functions on motor control circuits
• Used for interval timing in process control installations
• Can be used for time-based signalling in building management systems

It functions between -10 °C and 50 °C, enabling use across typical indoor industrial ambient conditions.

It uses a plug-in Terminal format for straightforward insertion into compatible sockets or relay bases for quick replacement.

It has approvals in line with IEC 60664-1, EN 61812-1, UL 508 and CSA C22.2 No. 14, indicating compliance with international electrical safety requirements.

The unit provides multiple timer functions allowing selection of different delay and Pulse behaviours to suit various control logic needs.
