Product Overview

The 3BSE050091R65, officially designated as the ABB PFEA112-65, is a high-performance tension electronic device engineered for precision measurement and control of web tension in industrial processing applications. This advanced tension controller belongs to ABB’s PFEA series of tension electronics and serves as a critical component in automated tension control systems, enabling real-time monitoring and regulation of material tension during winding, unwinding, and processing operations. The PFEA112-65 receives signals from up to two tension sensors (load cells), processes these inputs through sophisticated control algorithms, and provides accurate tension feedback for closed-loop control. With its compact design, flexible mounting options, and robust IP65 protection, the PFEA112-65 is ideally suited for demanding industrial environments across paper, film, metal foil, textile, and printing applications. The 3BSE050091R65 features a 2×16 character multilingual interactive display for real-time tension monitoring and configuration, with the added capability of PROFIBUS-DP communication for seamless integration with higher-level control systems.
