Product Name: Tension Electronics PFEA111-20

Product Description: The ABB PFEA111-20 is a tension electronics module designed for measuring and monitoring tension in web materials such as paper, film, and textiles. It is a key component in web tension systems, often used in printing, converting, and winding applications. This module typically connects to two load cells and provides both voltage and current outputs representing the measured tension (sum and difference of the load cell signals). It features an adjustable filter to optimize the output signal and a digital display that shows individual load cell signals (A, B) as well as their sum (A+B) and difference (A-B). The PFEA111-20 is designed for industrial control systems and often comes with a user manual for easy setup and operation.
