Omron G2R-1-SN 110VDC (S) Plug-in Relay Technical Guide

The Omron G2R-1-SN 110VDC (S) plug-in relay is a general-purpose industrial relay developed for control panels, interface circuits, and automation systems using 110 VDC control power. It is part of Omron’s G2RS series, a widely used family of slim plug-in relays designed for practical panel installation and easy replacement.

This relay uses a 1-pole SPDT contact arrangement, giving it one changeover contact for flexible switching logic. It is commonly selected when a control system needs to switch a load, isolate a signal, or convert one control condition into another within an electrical cabinet.

Technical Features

The G2R-1-SN 110VDC (S) has a 110 VDC coil and a rated carry current of 10 A. The plug-in construction supports quick service work because the relay can be removed from its socket without disturbing field wiring. In production lines and automated machinery, this can make replacement faster and reduce unnecessary downtime.

The relay includes a transparent case, LED indication, and mechanical operation indicator. These visual features are helpful during commissioning and fault-finding because technicians can quickly check whether the relay has energized.

Application Areas

This relay is often used in DC control panels, machinery interface circuits, alarm circuits, control signal routing, and PLC-related installations. Its 110 VDC coil makes it relevant for systems where higher DC control voltage is preferred for long wiring runs or established plant standards.

Omron G2R-1-SN 110VDC (S) FAQ

What type of relay is Omron G2R-1-SN 110VDC (S)?

It is a general-purpose plug-in relay with a 110 VDC coil and SPDT contact configuration.

Can this relay be used in industrial control panels?

Yes. It is designed for control panel and interface applications where socket mounting and visual status indication are useful.

Does it include an LED indicator?

Yes. The SN version includes LED indication along with a mechanical indicator for easier status checking.

What does the 10 A rating mean?

The 10 A rating refers to the relay’s rated carry current. Actual switching suitability depends on load type, voltage, and application conditions.

Why choose a plug-in relay instead of a PCB relay?

A plug-in relay is easier to replace in the field. It is better suited for maintenance-friendly panel designs where service access matters.
