Omron H3RN Series Timer Relay, 24V AC Supply Voltage, 0.1s to 10min Time Range - H3RN-1 24VAC

This timer relay is a compact, multifunction control device designed for timed switching in 24V AC control systems. It fits into a socket-mounted arrangement and provides single-contact switching suitable for automation and panel-based installations, operating across a selectable delay range to manage sequential or timed functions in electrical and mechanical equipment.

Features and Benefits:

• Multifunction timing covers 0.1s to 10 min for flexible sequencing
• Single SPDT contact provides changeover switching capability
• 3A contact rating supports modest load switching in control circuits
• Socket Terminal format enables quick replacement and maintenance
• Rated to operate between -10°C and 55°C for typical indoor environments
• Conforms to EN UR CSA standards for recognised industrial acceptance

Applications

• Suitable for timing control in industrial control panels 24V AC
• Ideal for sequencing motors and actuators in automation systems
• Used for delay and interlock functions in electrical control cabinets
• Can be used for timed indication and signalling circuits in machinery

What supply type and voltage does it require?

It requires a 24V AC supply and is configured for AC operation only.

How many contacts and what switching arrangement are provided?

It has a single changeover contact with SPDT configuration for switching between two outputs.

What environmental limits should be observed during installation?

The device is rated for operation down to -10°C and up to 55°C, installations should avoid exposure beyond these temperatures.

How does the mounting Interface affect serviceability?

The socket-mounted Terminal arrangement allows straightforward removal and replacement without direct wiring changes.
