Omron G2R-1-SNI 110VAC (S) Relay Socket Overview

The Omron G2R-1-SNI 110VAC (S) relay socket is a compact general-purpose plug-in relay designed for industrial control panels, interface circuits, automation systems and switching applications where clear status feedback matters. As part of the Omron G2RS family, this model uses a 110 VAC coil and a single-pole double-throw contact structure, commonly described as SPDT or 1 Form C.

Technical Characteristics

This relay is built for socket mounting and is typically used with compatible Omron P2RF and P2R socket families. The contact rating reaches 10 A for resistive loads, making it suitable for many panel-level switching duties. Its plug-in terminal structure supports easier replacement during maintenance compared with permanently wired relay formats.

The 110 VAC version is especially relevant in systems where the control voltage is derived from AC panel supply lines. Omron lists the G2R-1-SNI AC100/(110) variant with LED and mechanical operation indicators, a latching lever, SPDT contact form, Ag alloy contact material and 10 A contact rated load. The built-in LED helps technicians confirm coil energization, while the mechanical indicator provides a second visual cue even in dense control cabinets.

Where It Is Used

This relay is commonly selected for machine control, HVAC panels, motor auxiliary circuits, lighting interfaces, alarm circuits and general automation logic. Because it includes a test button, commissioning teams can verify circuit behavior without immediately changing the full control sequence. That makes the product practical for troubleshooting and preventive maintenance.

Installation and Selection Notes

Before choosing this model, confirm coil voltage, socket compatibility, load type and expected switching current. Resistive and inductive loads behave differently, so engineers should check the actual load profile before installation. For broader Omron relay information, visit Omron product information.

FAQ

What is Omron G2R-1-SNI 110VAC (S)?

It is a plug-in general-purpose relay with a 110 VAC coil, SPDT contact arrangement, LED indication, mechanical operation indicator and test button.

Is this relay suitable for control panels?

Yes. Its slim plug-in design, socket mounting and visual indicators make it well suited for electrical control panels and automation cabinets.

What does SPDT mean?

SPDT means single-pole double-throw. The relay has one common contact that can switch between normally open and normally closed paths.

Why is the test button useful?

The test button allows controlled manual operation during setup or diagnostics. It should only be used when the connected load and circuit are safe to test.
