Omron G2R-1-S 230VAC (S) Relay Socket Technical Guide

The Omron G2R-1-S 230VAC (S) relay socket is a plug-in general-purpose relay for control panels and automation systems using 230 VAC control voltage. It is built for reliable switching, clear panel organization, and straightforward servicing in industrial electrical environments.

Technical Specifications

This relay has a 230 VAC coil. The rated coil current is approximately 4.4 mA at 50 Hz and 3.8 mA at 60 Hz. Coil resistance is approximately 27,172 Ω. The must-operate voltage is 80% max. of rated voltage, and the must-release voltage is 30% max. The maximum coil voltage is specified as 110% of rated voltage.

The contact arrangement is SPDT, or 1 Form C. The relay is rated for 10 A at 250 VAC and 10 A at 30 VDC on resistive loads. For inductive loads, it supports 7.5 A at 250 VAC and 5 A at 30 VDC. Maximum switching voltage is 440 VAC and 125 VDC, with maximum switching power up to 2,500 VA or 300 W depending on the load.

Best-Fit Applications

The Omron G2R-1-S 230VAC (S) relay socket is commonly used in European-style control panels, machinery automation, HVAC control circuits, pump panels, and industrial switching systems where 230 VAC control is standard. Its plug-in design makes it easier to remove and replace during inspection or service.

Operational Benefits

The relay includes a mechanical indicator for quick visual status checks. Its label facility supports organized panel documentation, helping technicians identify circuits faster. The socket-compatible design also supports clean installation and efficient troubleshooting.

Omron G2R-1-S 230VAC (S) FAQ

What is Omron G2R-1-S 230VAC (S) used for?

It is used for switching and isolation in automation panels, machinery control circuits, HVAC systems, and industrial electrical cabinets using 230 VAC control voltage.

What is the contact rating?

For resistive loads, the relay is rated at 10 A at 250 VAC and 10 A at 30 VDC. Inductive-load ratings are lower and must be matched with the application.

Does it have a visual indicator?

Yes. The model includes a mechanical operation indicator, helping technicians confirm relay status during testing and maintenance.

Is this a socket-mounted relay?

Yes. It is designed as a plug-in relay, making replacement easier compared with fixed PCB-mounted relays.

Can it switch both AC and DC loads?

Yes, it can switch both AC and DC loads within its rated limits. The load type, voltage, current, and inductive behavior should always be reviewed before installation.
