Siemens 6SL3243-0BB30-1PA3 G120 Drive Control Unit

Siemens 6SL3243-0BB30-1PA3 is a SINAMICS G120 Control Unit CU230P-2 DP with integrated PROFIBUS DP, designed for use with modular SINAMICS G120 and G120P drive systems. It provides the control interface and I/O needed to manage the power module and motor via the G120 family, including 6 digital inputs, 3 digital outputs, 4 analog inputs, and 2 analog outputs, plus a motor temperature sensor input. The unit supports a 24 V DC power supply with one PSU input and two PSU outputs (10 V DC and 24 V DC) for logic and peripheral devices, and offers USB and MMC interfaces for configuration and monitoring. Its protection rating is IP20, and its compact enclosure measures approximately 7.83 in high, 2.87 in wide, and 2.59 in deep, making it suitable for cabinet installations in industrial automation. Typical applications include control of pumps, fans, and compressors where a SINAMICS G120 drive is employed, leveraging the CU230P-2 DP’s integrated PROFIBUS DP networking to connect to PLCs and other field devices. This combination supports reliable, modular motor control with a defined, multi-sensor I/O set and straightforward configuration for standard industrial tasks.
