Omron G2R-1-SN 240VAC (S) Plug-in Relay Technical Overview

The Omron G2R-1-SN 240VAC (S) plug-in relay is a general-purpose electromechanical relay designed for industrial AC control circuits. With a 240 VAC coil, it is suitable for control panels where higher AC control voltage is already used as part of the machine or facility standard.

This model belongs to Omron’s G2RS series and uses a single-pole SPDT contact form. The relay provides a 10 A rated carry current and supports changeover switching, making it useful for auxiliary control, signal routing, alarm systems, and panel interface duties.

Technical Characteristics

The G2R-1-SN 240VAC (S) is a plug-in relay, meaning it is designed for use with a compatible relay socket. This format is highly practical in electrical cabinets because it separates the relay body from the wiring base. During maintenance, the relay can be replaced quickly without rewiring the panel.

The transparent case, LED indicator, and mechanical indicator give technicians clear feedback during operation. In real control panels, this matters because relay status is often checked under time pressure during commissioning or troubleshooting.

Use in Control Panels

This relay can be used in industrial machinery, HVAC control systems, process automation panels, auxiliary switching circuits, and interface points between control devices. Its 240 VAC coil should always be matched with the correct control supply and verified against the application’s electrical requirements.
