Description
Siemens 6SL3244-0BB12-1BA1
SINAMICS G120 Control Unit CU240E-2 | RS485 Communication | Integrated Safety | IP20
Product Detailed Description
The Siemens 6SL3244-0BB12-1BA1 is a SINAMICS G120 CU240E-2 control unit with an RS485 interface and integrated Safe Torque Off (STO) functionality. It is designed to work with a compatible SINAMICS G120 power module to control motor-drive applications. The control unit does not include the power module or operator panel.The unit supports USS communication over RS485, V/f control, flux-current control, and sensorless vector control. Its I/O includes six standard digital inputs, configurable fail-safe input functionality, two relay changeover outputs, two differential analog/digital inputs, and two non-isolated analog outputs. It is intended for industrial drive systems that require configurable motor control and integration with machine-level automation.
