The Omron G2R-1-SNDI DC24(S) is a G2RS-series general-purpose relay with a 24V DC coil and SPDT contact arrangement.
The SPDT form (one common, one N.O., one N.C.) covers simple on/off or changeover logic. Dielectric strength is 5,000V AC between coil and contacts, so it isolates the 24V DC control side from the load circuit cleanly. The LED indicator and push-to-test button are on the relay itself, which helps during panel commissioning — you can cycle the relay manually without energizing the coil, and the LED confirms coil power is present. Electrical durability is rated at 100,000 operations at rated load; mechanical durability reaches 10,000,000 to 20,000,000 cycles, so the wear life is in the coil and contacts, not the mechanism.
