Siemens 6SL3244-0BB13-1PA1 SINAMICS G120 CU240E-2 DP-F PROFIBUS Safety VFD Control Unit

The Siemens 6SL3244-0BB13-1PA1 is a SINAMICS G120 CU240E-2 DP-F control unit with PROFIBUS DP communication and Safety Integrated STO (SS1, SLS, SSM, SDI), offering 6 digital inputs, 2 analog inputs, and 2 analog outputs. It draws a maximum of 0.50 A at 24 V DC, dissipates 5.50 W, and carries IP20 / UL open type protection for operation from -10°C to 55°C.

Technical Specifications

Selection Notes

The -F suffix and Safety Integrated STO/SS1/SLS/SSM/SDI functions mark this as the fail-safe control unit; pick it over a non-F CU240E-2 DP when the application needs a safety-rated stop or speed-monitoring function without a separate safety relay. PROFIBUS DP fixes the fieldbus choice on this unit, where a PROFINET-based CU240E-2 PN-F is the equivalent for an Ethernet-based line. Sensorless vector and encoderless torque control cover open-loop speed/torque regulation, but no encoder feedback input is available here, so closed-loop control needs a different CU240E-2 variant.

Applications

Controls a SINAMICS G120 Power Module in PROFIBUS-networked machinery that needs a functional-safety stop, such as conveyor sections, mixers, or fans with a Safe Torque Off interlock.
