ABB 64610805 RTAC-01 ACS800 frequency converter is equipped with a pulse encoder interface module.

Product Description

RTAC-01 (Part No.: 64610805) is a pulse encoder interface module for ABB ACS800 inverters, serving as the speed feedback acquisition unit of the drive system. The module receives pulse signals from incremental encoders, performs signal isolation, shaping and conversion, and feeds motor speed and position data back to the inverter main control board to realize high-precision vector control and closed-loop speed regulation. It is equipped with signal loss detection and fault diagnosis functions and features strong anti-interference performance. It is widely used for encoder signal acquisition in ACS800 single-drive / multi-drive systems, acting as a critical spare part for closed-loop speed regulation applications.
