The Siemens 6AG1244-0BB12-2FA0 SIPLUS SINAMICS G120 CU240E-2 PN Control Unit is designed for industrial drive applications requiring PROFINET connectivity, flexible motor regulation, and integrated safety functions. Based on the standard 6SL3244-0BB12-1FA0, this SIPLUS version features conformal coating and an extended operating temperature specification of -20 to +55 °C.
The CU240E-2 PN supports V/f control and sensorless vector control, providing flexible options for operating compatible SINAMICS G120 drives. Its two PROFINET interfaces enable integration into Industrial Ethernet networks, while the onboard I/O includes six digital inputs, three digital outputs, two analog inputs, and two analog outputs. A PTC/KTY interface is also available for compatible motor-temperature monitoring.
With Safety Integrated STO, USB and SD/MMC interfaces, and flexible signal configuration, the 6AG1244-0BB12-2FA0 is suitable for automated machinery, conveyor systems, pumps, fans, and other motor-driven equipment. It is supplied as a control unit without a Power Module, so the appropriate G120 power component must be selected separately.
