Siemens 6SL3244-0BB00-1PA1 Profibus DP Interface Module

CU240B-2 DP B-type PROFIBUS DP control unit (Siemens 6SL3244-0BB00-1PA1) for SINAMICS G120 drives delivers a dedicated PROFIBUS DP interface and integrated I/O for motor control. It provides 4 digital inputs, 1 digital output, 1 analog input, and 1 analog output, plus a PTC/KTY/ThermoClick interface for temperature sensing and safety wiring. The unit includes USB and SD/MMC interfaces for parameter storage, diagnostics, and log data, all housed in an IP20-rated enclosure for use in standard industrial environments. Operating temperature is specified as 0 to +50 °C ambient, and it is designed without a Power Module and operator panel, meaning those components are supplied separately as part of the drive system. This CU240B-2 DP configuration foregrounds PROFIBUS DP communication, enabling the SINAMICS G120 drive to exchange control and status data with DP-systems and other DP-enabled devices on the network. As a component of Siemens SINAMICS, it is intended for use in applications requiring robust propulsion or drive control where a DP backbone is present, such as material handling, processing lines, and general-purpose industrial motion. The 6SL3244-0BB00-1PA1 variant is specified as a B-type DP interface unit with the described I/O set, and it is sold as a replacement spare part for the CU240B-2 DP family.
