Siemens 6SL3255 0AA00 4CA1 Basic Operator Panel LCD

The Siemens 6SL3255-0AA00-4CA1 Basic Operator Panel (BOP-2) is the dedicated LCD-based human-machine interface for SINAMICS G120 drives. This compact, two-line monochrome LCD display provides local parameter editing and status readouts for the SINAMICS G120 family—G120, G120C, G120P, and G120X—allowing operators to adjust speed references, monitor run states, and view fault or diagnostic information without needing a PC. With a panel-mountable enclosure measuring 70 x 106.85 x 19.6 millimeters, the BOP-2 is designed for integration into standard control cabinets, enabling quick, on-site interactions with the drive and consistent presentation of key data across different G120 configurations. The 6SL3255-0AA00-4CA1 designation identifies this unit as Siemens' official BOP-2 operator panel accessory for SINAMICS G120 drives, and official catalog entries and data sheets corroborate its role as the dedicated interface for setup, monitoring, and basic operation tasks.
