Omron G2R-1-S 12VDC (S) Relay Socket Technical Guide

The Omron G2R-1-S 12VDC (S) relay socket is a compact plug-in relay designed for control circuits that use 12 VDC power. It is widely used in automation panels, machine control, interface circuits, and electrical systems where dependable switching and simple maintenance are important.

Technical Overview

This model has a 12 VDC coil with a rated current of approximately 43.2 mA and a coil resistance of 278 Ω. Its coil power consumption is approximately 0.53 W. The must-operate voltage is 70% max. of the rated voltage, while the must-release voltage is 15% min. The maximum coil voltage is 110% of rated voltage.

The relay uses a 1-pole SPDT contact arrangement. For resistive loads, it is rated at 10 A at 250 VAC and 10 A at 30 VDC. For inductive loads, it supports 7.5 A at 250 VAC and 5 A at 30 VDC. Maximum switching capacity reaches 2,500 VA for resistive AC loads and 300 W for resistive DC loads.

Why This 12VDC Version Matters

The 12 VDC coil version is useful in low-voltage control systems, battery-backed circuits, compact automation equipment, and interface modules. It allows a low-voltage DC signal to control higher-load circuits safely through isolated relay contacts.

Practical Application Areas

The Omron G2R-1-S 12VDC (S) relay socket is commonly found in industrial control panels, test equipment, alarm systems, machine interfaces, and automation modules. Its plug-in terminal structure supports faster replacement, while the mechanical indicator helps technicians verify relay operation visually.

Omron G2R-1-S 12VDC (S) FAQ

What is the coil rating of Omron G2R-1-S 12VDC (S)?

The relay has a 12 VDC coil rated at approximately 43.2 mA, with a coil resistance of 278 Ω and power consumption of about 0.53 W.

Is this relay suitable for DC control circuits?

Yes. The 12 VDC coil makes it appropriate for DC control systems, low-voltage panels, battery-powered circuits, and signal-interface applications.

What is the contact configuration?

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

What loads can it switch?

It can switch 10 A at 250 VAC or 10 A at 30 VDC for resistive loads. For inductive loads, ratings are lower and should be checked against the circuit design.

Is it easy to replace during maintenance?

Yes. Because it is socket-mounted, technicians can replace the relay without changing the wiring, provided the socket and circuit are correctly installed.
