Product Description
ABB FEN-11 Absolute Encoder Interface Module
The ABB FEN-11 is a high-performance absolute encoder interface module engineered for seamless integration into industrial control systems and variable frequency drives. This versatile module facilitates precise motor speed and position feedback by supporting both absolute and TTL encoder signals. It features three distinct D-sub connector interfaces designated for TTL IN (X41), ABS IN (X42), and TTL OUT (X43). To ensure reliable operation and easy troubleshooting, the FEN-11 is equipped with intuitive STATUS and ENC ST LED diagnostic indicators. Flexible voltage configuration is made possible via side-mounted jumpers, allowing users to select appropriate supply levels for TTL (+24V, +5.5V) and ABS (+5.5V, +8V) encoders. Complete with a 6-position terminal block for power and digital inputs, this module mounts securely on a DIN rail or chassis, connecting directly to the drive’s backplane via a robust bus connector.
