Omron G2R-1-SNI 120VAC (S) Relay Socket Technical Guide

The Omron G2R-1-SNI 120VAC (S) relay socket is a plug-in electromechanical relay from the G2RS series, widely used in automation panels and industrial control systems. It is designed for applications that require a 120 VAC coil, compact mounting, reliable switching and easy visual status checking.

Main Technical Features

This model uses an SPDT contact configuration, also known as 1 Form C. It is rated for 10 A carry current and belongs to the general-purpose relay category. The relay includes LED indication, a mechanical operation indicator, transparent case design and a test button. These features are valuable in real-world panel environments because maintenance teams can quickly identify relay status without unnecessary dismantling.

The 120 VAC coil version is a strong fit for North American-style control voltage systems and industrial machinery where 120 VAC control circuits are standard. Its plug-in terminal format allows quick replacement when used with compatible Omron sockets such as P2RF and P2RFZ socket options.

Practical Application Areas

Typical use cases include PLC output isolation, motor control auxiliaries, solenoid switching, HVAC equipment, lighting control, alarm panels and machine safety-related auxiliary circuits. The relay is not a complete safety relay by itself, but it can be used as a dependable interface component in properly engineered systems.

Why Engineers Choose This Type

The main advantage of this relay is serviceability. A plug-in relay can be replaced faster than a soldered or permanently wired component. The LED indicator confirms coil status, while the mechanical flag helps verify physical operation. The test button is useful during commissioning, provided the circuit has been checked for safe manual activation.

FAQ

What is the Omron G2R-1-SNI 120VAC (S) used for?

It is used for switching and interface tasks in control panels, automation machines and electrical distribution systems that use 120 VAC control voltage.

Does it have a visual indicator?

Yes. The model includes LED indication and a mechanical operation indicator, helping technicians confirm both electrical and mechanical relay status.

What contact type does it use?

It uses an SPDT contact form, allowing one common terminal to switch between normally open and normally closed contacts.

Is the test button always safe to press?

No. The circuit, load and operating conditions should be checked first. Manual testing can energize connected equipment, so it should be done only under controlled conditions.
