Siemens 6SL3055-0AA00-5BA3 Simatic S7-300 Module

Siemens 6SL3055-0AA00-5BA3 Version D is a sensor module (SMC20) that provides an encoder connection interface for SINAMICS S120 servo drives. The IP20-rated module accepts signals from incremental encoders and conditions the feedback for reliable position and speed control, offering a 500 Hz bandwidth to support precise motion feedback. Designed to work with SINAMICS S120 systems, the 6SL3055-0AA00-5BA3 is documented in positioning configurations associated with S7-300 PN environments, aligning with classic STEP 7 workflows. The unit is powered from a 24 V DC supply and is packaged in Siemens' compact sensor-module form factor, ensuring compatibility within standard automation installations. This Version D variant corresponds to the 6SL3055-0AA00-5BA3 part number and is intended specifically for encoder interfacing in SINAMICS applications where reliable incremental-encoder feedback is required for accurate servo control.
