The height is 100 mm and the depth is 124.5 mm, with a required top clearance of 40 mm and bottom clearance of 40 mm for wiring access and heat dissipation. Mounting is by screw or snap-on onto the DIN rail, both methods listed as supported. ## What the ratings decide in the BOM This is the control unit of the SIMOCODE pro S system — it handles the logic, the 4 digital inputs, and the relay output for motor starting and protection. The 24 V rated supply powers the unit and the connected sensors. The 4 digital inputs accept 24 V signals from pushbuttons, selector switches, or PLC outputs. The unit also provides current detection for the motor circuit, feeding back the actual load current to the protection algorithms.","metaTitle":"Siemens 3UF7020-1AB01-0 SIMOCODE pro S, 4 DI, relay out","metaDescription":"Siemens 3UF7020-1AB01-0 SIMOCODE pro S motor management control unit. 4 digital inputs, relay output, 24 V rated, direct start, current detection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["PLC Communication Modules"],"specifications":{"Top":"40 mm","Left":"0 mm","Depth":"124.5 mm","Right":"0 mm","Solid":"1x (0.5 ... 2.5 mm²), 2x ( 0.5 ... 1.5 mm²)","Width":"22.5 mm","title":"3UF7020-1AB01-0","Bottom":"40 mm","Height":"100 mm","at 24 V":"2.2 ms","at 60 V":"0.55 A","at 120 V":"6 A","at 125 V":"0.25 A","at 230 V":"3 A","1 Maximum":"2 000 m","2 Maximum":"3 000 m; max. +50 °C (no protective separation)","3 Maximum":"4 000 m; max. +40 °C (no protective separation)","at 50 °C":"6 A","at 60 °C":"5 A","Web Server":"No","Rated Value":"24 V","description":"Basic unit SIMOCODE pro S, PROFIBUS DP interface 1.5 Mbit/s, 4I/2O freely parameterizable, Us: 24 V DC, input for thermistor connection Monostable relay outputs, expandable by a multifunctional module","Control Unit":"Yes","Direct Start":"Yes","Relay Output":"Yes","Digital Input":"Yes","Initial Value":"0.85","Shared Device":"No","Slide Control":"No","Test Function":"Yes","Valve Control":"No","During Storage":"-40 ... +80 °C","I&M3 -
