Integrator's terse spec recap
The Omron G2RV-ST700 DC12 is a slim-style relay with an integrated low-profile socket, rated 6 A at 250 V AC (resistive) and 6 A at 30 V DC (resistive). Coil pulls 0.3 W at 12 V DC. SPDT contact form. Screw termination. DIN-rail mount. Width of relay and socket is 0.24 in — fits tight panel rows.
What the ratings mean for fit
The 6 A resistive rating at 250 V AC covers general-purpose switching for solenoid valves, contactor coils, and indicator loads. The 2.5 A AC rating at 250 V is the inductive / motor-duty derating — use that for small motors or transformer primaries. The 0.3 W coil draw means the relay adds negligible heat to a crowded DIN-rail enclosure and can be driven directly by a PLC digital output without an interposing transistor.
Panel integration
DIN-rail mount with screw termination. The 0.24 in width per relay-and-socket assembly allows dense packing on the rail — roughly 50 units per foot. IP20 rated, so suitable for enclosed control panels only; not for washdown or outdoor locations.
