G2R terminal footprint, DC5-24 control
The Omron G3R-OD201SN-UTU DC5-24 is a solid state overload relay in Omron's G3R line, built to drop into the same terminal footprint as the G2R electromechanical relay family — meaning an existing G2R socket and wiring layout carry over without re-laying the DIN-rail pattern or re-tagging the terminals. The "DC5-24" suffix designates a DC control input range of 5 to 24 VDC, so the coil-side drive comes from a low-voltage logic or PLC output rather than a 120 VAC rail — relevant when the upstream is a 24 VDC control system and you want a solid-state output stage sitting on a G2R-style footprint.
