FEN-31 ABB HTL encoder interface module

ABB FEN-31 HTL encoder interface module

The ABB FEN-31 is an HTL encoder interface module designed to bridge high-resolution encoders with industrial automation systems, such as ACS880 variable frequency drives (VFDs). Engineered for precision control applications, this module converts HTL (push-pull) encoder signals into TTL-level RS422 outputs, enabling real-time feedback for motor speed, position, and direction monitoring. Its robust design ensures reliable operation in harsh industrial environments, while flexible power options and signal compatibility make it adaptable to diverse automation setups. The FEN-31 is a critical component for industries requiring high-accuracy motion control, including material handling, robotics, and process automation.
