B&R 8BAC0120.000-1 Motion Control Module

B&R 8BAC0120.000-1 Motion Control Module (ACOPOSmulti Encoder Interface)

 

 

The B&R 8BAC0120.000-1 is a motion control plug-in module used in the B&R ACOPOSmulti servo drive system. It is specifically an EnDat 2.1 encoder interface module, responsible for processing high-precision motor feedback signals.

It is not a standalone controller or PLC, but a servo drive feedback/position measurement module inside a motion system.
