Omron H3Y-4 Series Timer Relay, 0.1 to 3min Time Range, 100/120V AC Supply Voltage - H3Y-4 100-120VAC 3M

This timer relay is a Compact control device designed for time-delayed switching in industrial control panels and automated systems. It provides adjustable delay timing for on/off sequences and is intended for DIN-rail installation in electromechanical and electronic control environments. The unit operates from mains AC or a DC supply and is suitable where a multi-contact time-delay solution is required.

Features and Benefits:

• Four changeover contacts provide simultaneous multi-circuit control
• Adjustable delay from 0.1 to 3 min for precise timing control
• Rated contact current 5A supports common control loads
• Switching capability up to 250V AC for versatile interfacing
• Plug-in terminals enable quick replacement and maintenance
• IP40 enclosure allows indoor panel mounting in protected locations

Applications

• Suitable for sequenced motor start–stop control in panels
• Ideal for timed valve or actuator control in process systems
• Used with indicator circuits requiring delayed activation
• Can be used for lighting control in industrial automation schemes
• Suitable for interlock timing between machine subassemblies

What mounting method does it use for panel integration?

It mounts on a standard DIN rail, allowing straightforward fitting within control enclosures.

Which supply voltages can be applied for timing operation?

It accepts 100/120V AC for the primary timing supply and has a 125V DC supply rating for alternative power arrangements.

How many timing functions are available on the unit?

The device provides a single timing function configurable across its adjustment range.

What environmental limits should be observed during installation?

The unit is rated to operate between −10 °C and 50 °C and is intended for indoor use within panels due to its IP40 rating.

What approvals support use in regulated installations?

It carries approvals including UL508, CSA C22.2 No.14, IEC 60664-1, CCC GB/T 14048.5 and Lloyd’s classification.
