The ABB PFEA112-65 is a high-performance tension electronics unit designed to process signals from load cells in web-processing industries like paper, film, and textiles. As part of the Tension Electronics PFEA series, the “112” model is the advanced version, featuring PROFIBUS-DP connectivity for seamless integration into higher-level control systems. The “65” suffix indicates its ruggedized IP65-rated housing, which allows it to be mounted directly in harsh production environments without the need for an additional protective cabinet. It features a user-friendly interface for calibration and provides highly accurate, real-time web tension data to ensure consistent product quality and prevent material breakage.

Model Comparison: PFEA112-65 vs. Similar Models
The PFEA112-65 is the advanced, high-protection counterpart to the PFEA111. While both models support multiple load cell inputs, the PFEA112 includes an integrated PROFIBUS-DP interface, which is essential for modern automated plants. Compared to the PFEA113 (the premium version), the 112 provides essential tension monitoring and digital communication but lacks some of the more complex multi-zone summing features found in the 113. Additionally, the 3BSE050091R65 version is physically distinct from the R00 (IP20) version, as it is encased in a robust aluminum enclosure rather than being designed for DIN-rail mounting inside a panel.
Operational Guidelines
- Environmental Sealing: To maintain the IP65 rating, ensure all cable glands are properly tightened and that any unused cable entries are sealed with the original plastic plugs.
- Load Cell Calibration: Use the “Step-by-Step” calibration wizard on the local display. Ensure the web is completely slack during the “Zero Set” procedure to avoid permanent offset errors.
- Profibus Termination: If the PFEA112-65 is the last device on the Profibus segment, ensure the termination resistor is switched to “ON” within the D-sub connector or via internal jumpers to prevent data reflections.
- Shielding and Grounding: The load cell cables must be shielded and the shields grounded only at the PFEA112-65 end to avoid ground loops that can cause signal “noise” and erratic tension readings.
