Overview
ABB NTAC-02 is a pulse encoder interface module designed specifically for ABB frequency converter systems. This interface module converts pulse signals from external encoders into digital signals that frequency converters can recognize, enabling high-precision closed-loop motor control. The NTAC-02 supports multiple encoder signal types and is ideal for applications requiring accurate speed feedback, position tracking, and synchronous motor operation.
