Omron H3RN Series Timer Relay, 1-Contact, 24 V ac 24V ac, 0.1 s to 10 min, Multifunction-Function, SPDT Switch

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.

• 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

• 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

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

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

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

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