The G2R-2-SNDI DC12(S) is an Omron general-purpose relay with a DPDT (2 form C) contact arrangement and a 12 VDC coil. It integrates an LED indicator, a suppression diode, and a manual test button into the relay body, which simplifies panel wiring and troubleshooting. The 12 VDC coil is the standard control voltage for many PLC and industrial control circuits, so this relay drops into existing 12 VDC logic without a separate power supply. The built-in diode suppresses the inductive kickback from the coil, which protects the driving transistor or PLC output. Contact material is silver cadmium oxide (AgCdO), which handles moderate inrush and arc erosion better than fine silver. This makes the relay suited for switching small motor loads, solenoids, and lamp loads where the initial current surge exceeds the steady-state rating.
Sourcing and lifecycle
Because it is an active Omron catalog item, the buyer can expect consistent supply and manufacturer support. The part is specified into BOMs with confidence that it will remain available for the foreseeable future.
Mounting and integration
The relay's built-in test button allows manual actuation during commissioning without energizing the coil. The LED indicator provides immediate visual confirmation of coil state, which speeds fault isolation on the panel. The DPDT contact configuration gives two independent switching channels in a single package, which saves DIN-rail space compared to using two separate SPDT relays. The silver cadmium oxide contacts are rated for general-purpose switching; verify the specific load current against the datasheet's resistive and inductive ratings.
