It carries 4 digital inputs and a relay output, and it integrates a control unit, direct start capability, and a test function into a single 22.5 mm-wide housing. ## Panel fit and wiring constraints At 22.5 mm wide, 100 mm tall, and 124.5 mm deep, this unit occupies a single standard DIN-rail module slot. The fastening method accepts both screw and snap-on mounting, so it locks onto the rail without tools or releases with a screwdriver for panel rework. ## Rated supply and output current The control supply is rated 110 to 240 V AC/DC at 50/60 Hz. The altitude derating is straightforward — full rating up to 2000 m, then derated to 3000 m at +50 °C and 4000 m at +40 °C without protective separation.","metaTitle":"Siemens 3UF7020-1AU01-0AX0 SIMOCODE pro S Basic Unit, 4 DI","metaDescription":"Siemens 3UF7020-1AU01-0AX0 SIMOCODE pro S basic unit, 22.5 mm wide, 4 digital inputs, relay output, rated 110-240 V AC/DC.
