The Siemens 6AG1244-0BB12-2PA1 SIPLUS SINAMICS G120 CU240E-2 DP Control Unit is designed for industrial drive applications that require PROFIBUS DP communication and flexible motor-control capabilities. Based on the standard 6SL3244-0BB12-1PA1, this SIPLUS version features conformal coating and an extended environmental specification for demanding industrial installations.
The CU240E-2 DP supports V/f control and sensorless vector control, allowing it to manage compatible SINAMICS G120 drive configurations. Its PROFIBUS interface enables communication with higher-level PLCs and distributed automation equipment. The integrated I/O includes six digital inputs, three digital outputs, two analog inputs, and two analog outputs, providing flexible signal-processing options for different motor-control applications.
The control unit also supports Safety Integrated STO and a PTC/KTY motor-temperature sensor interface. It is suitable for conveyor systems, pumps, fans, production machinery, and other motor-driven equipment using PROFIBUS-based automation architectures. The unit is supplied without a Power Module, so a compatible power component must be selected separately.
