Omron G2R-2-SD 24VDC (S) Relay Socket Explained

The Omron G2R-2-SD 24VDC (S) Relay Socket is one of the most practical relay options for modern industrial control panels using 24 VDC control power. It combines a plug-in structure, DPDT switching, mechanical indication, and built-in diode suppression in a compact relay body.

Core Specifications

This relay has a 24 VDC coil, approximate coil current of 21.6 mA, and coil resistance around 1,113 ohms. It is an 8-pin plug-in relay with a DPDT contact arrangement. The rated carry current for the two-pole model is 5 A. The built-in diode helps reduce coil-generated voltage spikes when the relay is switched off.

Because 24 VDC is one of the most common control voltages in automation panels, this model is frequently used with PLC systems, sensor circuits, machine controls, and relay interface modules. The mechanical indicator provides a practical visual signal, making troubleshooting faster and more intuitive for maintenance teams.

Panel Integration Benefits

The socket-mounted structure helps reduce service time. If a relay reaches the end of its service life, it can be removed and replaced without disturbing the main wiring. This supports cleaner panel design and more efficient maintenance planning. For related Omron components, visit Omron automation and relay solutions.
