ABB PFEA112-65 (3BSE050091R65) Tension Electronics Module for Process Control Systems

Product Description

The ABB PFEA112-65 (Part Number: 3BSE050091R65) is a high-precision tension electronics module designed for ABB's Process Control Systems, specifically engineered to measure and control web tension in industrial processes such as paper manufacturing, printing, metal processing, and textile production. This module interfaces with load cells and tension transducers to convert mechanical tension signals into digital data, featuring 65 N (Newton) measurement range, 16-bit analog-to-digital conversion, and built-in calibration capabilities. With robust galvanic isolation, redundant communication options, and compliance with IEC 61508 (SIL 2), the PFEA112-65 ensures accurate, real-time tension control, minimizing material waste and maximizing process efficiency in harsh industrial environments.

Key Functions

The PFEA112-65 tension electronics module delivers precise tension measurement and control for industrial web processes. Key functions include: High-precision tension measurement (0-65 N range, ±0.1% accuracy) via load cell/tension transducer input; 16-bit analog-to-digital (A/D) conversion for ultra-precise signal processing; galvanic isolation (2500 VAC) between field inputs and control electronics to eliminate ground loops and EMI; built-in automatic and manual calibration routines for easy setup and maintenance; redundant communication interfaces (PROFIBUS DP V1, Ethernet/IP) for seamless integration with ABB AC 800M/DCS systems; configurable alarm thresholds for over/under tension conditions with digital output signaling; and compliance with IEC 61508 SIL 2 for safety-critical applications. The module also features LED status indicators for power, communication, and fault conditions, and hot-swappable design for online maintenance.

Application Scenarios

The ABB PFEA112-65 tension electronics module is deployed in web tension control applications across industrial manufacturing sectors. In paper mills, it controls tension in paper machine forming, pressing, and drying sections to ensure uniform paper thickness and quality. For printing and packaging plants, it maintains precise web tension in flexographic, gravure, and offset printing presses, reducing print defects and material waste. In metal processing facilities, it regulates tension in aluminum foil, steel strip, and copper sheet production lines to prevent material stretching or tearing. The module is also used in textile manufacturing (fabric weaving/knitting) and plastic film production—all scenarios requiring accurate, real-time tension measurement and control for continuous web processes.
