Omron G2R-2-SNI 120VAC (S) Relay Socket: Technical Overview

The Omron G2R-2-SNI 120VAC (S) relay socket is a plug-in general-purpose relay designed for control panels, automation cabinets, and interface circuits where clear status indication and reliable switching are required. It belongs to Omron’s G2RS relay family and is commonly used when a 120 VAC coil voltage is preferred in industrial control environments.

Key Technical Characteristics

This model is built as a plug-in relay with a DPDT contact configuration, also known as 2 Form C. It provides a rated carry current of 5 A, making it suitable for many control and signal switching applications. The relay includes a mechanical indicator and LED indicator, helping technicians quickly identify operating status during panel inspection or troubleshooting.

The test button is useful during commissioning because it allows controlled manual operation without altering the wiring structure. Its transparent case also supports visual inspection, which is valuable in maintenance-heavy environments.

Where It Is Typically Used

The Omron G2R-2-SNI 120VAC (S) relay socket is frequently selected for control panels, HVAC systems, machine automation, alarm circuits, and auxiliary switching tasks. Because it uses a socket-mounted design, replacement can be performed faster than hard-wired relay changes, reducing panel downtime.

Why the 120VAC Coil Matters

A 120 VAC coil is often preferred in control systems where the control voltage already follows North American or mixed industrial panel standards. This helps simplify wiring architecture and reduces the need for additional control transformers in some installations.

FAQ

What is Omron G2R-2-SNI 120VAC (S)?

It is a plug-in, DPDT general-purpose relay with a 120 VAC coil, LED indication, mechanical indication, and test button.

Is this relay suitable for control panels?

Yes. Its plug-in structure, compact body, and visual indicators make it practical for control panel and interface applications.

What does DPDT mean?

DPDT means double pole double throw. It allows two separate circuits to be switched at the same time.

Why is the test button important?

The test button helps technicians verify relay operation during installation, maintenance, and troubleshooting without forcing the control signal externally.
