Siemens 6FX1145-4BA00 Encoder Board

The Siemens 6FX1145-4BA00 Encoder Board is a five-channel measuring circuit module (5-fold EXE) designed for use with SINUMERIK 805 CNC controls, functioning as the encoder interface and signal conditioning for feedback from multiple encoders; it captures encoder pulses, performs conditioning, and routes the processed signals to the drive or controller for precise motion control. In typical SINUMERIK 805 installations, this board sits in the encoder path to convert raw encoder data into robust, compatible signals that the motion system can interpret with consistency, and it is commonly described in catalogs and spare-parts listings as a MEASURING CIRCUIT MODULE, 5-FOLD EXE. The exact part number 6FX1145-4BA00 is documented by Siemens and appears in both official SINUMERIK references and third-party listings as an encoder/measuring circuit module for multi-encoder configurations, making it a targeted replacement option for legacy SINUMERIK 805 setups.
