Omron G2R-1-SN 24VAC (S) Plug-in Relay Guide

The Omron G2R-1-SN 24VAC (S) plug-in relay is a compact industrial relay designed for 24 VAC control circuits. It is commonly used in automation panels, HVAC controls, machine control systems, auxiliary switching circuits, and interface applications where serviceability and clear relay status are important.

This relay is part of the Omron G2RS family and features a 1-pole SPDT contact arrangement. With one changeover contact, it can switch between normally open and normally closed paths. Its rated carry current is 10 A, making it suitable for many control and interface duties when applied within the correct electrical limits.

Technical Features

The G2R-1-SN 24VAC (S) uses a 24 VAC coil and a plug-in terminal format. Socket mounting is one of its major practical advantages because it allows fast replacement and cleaner panel organization. This is especially useful in installations where relays are grouped together and labeled for maintenance.

The relay includes LED indication, a transparent case, and a mechanical indicator. These features support faster inspection during panel commissioning and fault diagnosis. Instead of relying only on measurements, technicians can visually confirm whether the relay is energized.

Application Suitability

This model is often used in 24 VAC control environments, including HVAC panels, low-voltage AC control circuits, automation interfaces, and equipment control systems. Its combination of compact design, visual indication, and plug-in serviceability makes it a practical component in organized control panel architecture.
