Rated at 24 V, the relay outputs handle 6 A at 50 °C and derate to 5 A at 60 °C — enough for direct switching of small contactors, solenoid valves, or indicator loads inside a control cabinet. ## Output current across the voltage range The relay contacts are rated for 6 A at 120 V and 3 A at 230 V, with lower ratings for DC loads: 2 A at 24 V, 0.55 A at 60 V, and 0.25 A at 125 V — the DC arc-quenching limit is the binding constraint, not the AC thermal rating. Active power consumption is just 0.7 W, keeping the thermal load low in a densely populated cabinet row. ## Built for the control cabinet IP20-rated with screw and snap-on mounting, this module is designed for dry indoor panels — not washdown zones — and can be mounted in any orientation. Operating temperature spans -25 to +60 °C, and the module is rated for altitudes up to 2000 m without derating; above that, the ambient ceiling drops to +50 °C at 3000 m and +40 °C at 4000 m when protective separation is absent.","metaTitle":"Siemens 3UF7300-1AB00-0 SIRIUS Digital Module, 4DI/2DO","metaDescription":"Siemens 3UF7300-1AB00-0 SIRIUS digital module, 4 digital inputs, 2 relay outputs, 24 V rated, 22.5 mm wide, IP20.
