Overview

The ABB PFEA112-20 (Part No. 3BSE030369R0020) is part of ABB’s PFEA series of tension electronics modules, engineered to deliver accurate and stable tension measurement in web-handling systems. It processes signals from load cells and converts them into actionable control outputs for drives and automation systems.

Moreover, the module features a multi-language digital display, configuration keys, and DIN-rail or IP65 mounting options, making it adaptable to both standard and harsh industrial environments. In addition to displaying sum, difference, or individual load cell signals, it supports redundant configurations and real-time diagnostics. Therefore, it’s widely used in industries where tension consistency directly impacts product quality, such as paper, film, foil, and textile production.

Technical Data

Typical Applications

• Paper & Film Production: Ensures consistent tension to prevent wrinkles, tears, or misalignment during processing.

• Foil Winding & Slitting: Regulates tension for high-quality edge finishes and uniform roll formation.

• Textile Processing: Uses load cell feedback to adjust motor speed and torque for optimal fabric handling.

• Plastic Extrusion & Metal Strip Handling: Provides precise tension control in continuous production systems, ensuring uniformity in material thickness and quality.

• Web Tension Control Systems: Widely adopted in industries where precise web tension directly impacts product quality and consistency.

Engineers appreciate the flexibility of its configuration, real-time diagnostics, and robust performance in both standard and IP65-rated enclosures, making it suitable for a wide range of industrial environments.
