What the ratings mean for fit
The Omron G2RV-ST700 DC24 is a slim-style relay from the G2RV-ST Series, switching SPDT contacts rated 6 A at 250 VAC resistive and 6 A at 30 VDC resistive — the same 6 A figure governs both AC and DC resistive loads, so the derating curve is simpler than on relays where the AC and DC numbers diverge. At 2.5 A / 250 VAC and 2 A / 30 VDC the inductive-contact ratings are lower; that second line tells you the contact life shrinks under motor or solenoid loads, so size up if your load is a small contactor coil or a valve solenoid rather than a resistive heater. Coil draws 0.3 W at 24 VDC nominal — that is a low-wattage hold, so the relay stays cool in a crowded DIN-rail row and the power supply sees negligible draw from the control circuit. The integrated low-profile socket (screw termination) saves the separate socket buy and the wiring step of seating a relay into a base; it ships as one unit, wire direct. Body footprint is 0.24 in wide by 3.46 in deep by 3.54 in tall — that 0.24 in width is the selling point: you pack roughly four relays into the space of a standard 1-inch-wide ice-cube relay. On a 12-inch DIN rail that means up to 50 relays before you need a second rail. IP20 means finger-safe terminals but no washdown tolerance — keep it inside the enclosure, not on the machine frame.
