What it is and where it slots into the panel
The Omron G3R-ODX02SN-UTU DC5-24 is a DC-output solid state relay with photocoupler isolation, listed as a TÜV-certified variant with a terminal footprint compatible with the G2R electromechanical relay family. It is built to be a drop-in solid-state upgrade for sockets already wired for the G2R series — same socket, no rewiring — so panel layouts that have run out of mechanical relay life can be converted to long-life DC switching without a layout change. The catalog record places the part in the Solid State Relays category, and the lifecycle stage on file is mature, meaning the part has settled into a long-running product line rather than a freshly introduced or a phased-out design.
The headline rating is a DC load current range of 25 mA to 3 A against a rated load voltage of 24 to 48 VDC, with a max applicable load envelope of 24 to 60 VDC. For the buyer that matters as a sizing question: any DC inductive or resistive load — solenoid valves, DC contactors, heating elements, indicator banks — must fall inside that 25 mA minimum (low-leakage loads below it stay marginal and need a bleeder) and stay inside the 60 VDC ceiling on transients. Output-stage SSR failure modes in DC service usually trace back to the user undersizing the transient suppressor on an inductive load or exceeding the I²t on switch-on. The 3 A upper limit on this part is the design budget — derate from there per the application note when the ambient inside the enclosure runs above the rated curve, and fit a flyback or TVS clamp across any DC inductive load because the SSR has no mechanical contact gap to absorb the kickback. On the input side, the relay accepts 4 to 30 VDC across an input impedance band of 0.9 to 6.5 kΩ ±20%, with a max operating input window of 26.4 to 32 VDC. The two input impedance bands tie to two sourcing profiles (low-impedance drive for 5 V logic, higher-impedance for 24 V control), so matching the BOM drive voltage to the correct variant on the order code matters — the impedance window tells the integrator which control rail the input stage was designed for. An operation indicator is fitted, giving a visible on/off cue at the relay face — useful for troubleshooting a field loop without pulling out a meter, and consistent with the socket-mount service the G2R footprint implies.
