Siemens 6SL3055-0AA00-5CA2 Encoder Sensor Module

The Siemens 6SL3055-0AA00-5CA2 SINAMICS SMC30 Sensor Module is a cabinet-mounted encoder signal processor with a 30 mm overall width, designed to interface incremental encoders with SINAMICS drives. It accepts TTL or HTL signals and supports combi-encoder SSI configurations, including SSI with incremental tracks or SSI without incremental signals, and it is specified as usable without a DRIVE-CLiQ cable. As part of the SINAMICS SMC30 family, the module evaluates encoder signals and transmits speed feedback to the drive, enabling precise velocity control in automated systems. This particular 30 mm-wide variant is designed for SINAMICS DCM (DC Master) configurations, with Siemens documentation noting compatibility for the 30 mm width in DCM setups, while wider 50 mm variants are not compatible with that topology.
