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 in various industrial processes. It is part of ABB’s web tension measurement systems. This module typically connects to two load cells, processes their signals, and provides both voltage and current outputs representing the measured tension. It features adjustable filtering for the output signals and displays tension values.

Key Features:

• Measures and monitors web tension.
• Connects to 2 load cells.
• Provides voltage and current outputs (A+B) with adjustable filtering.
• Displays tension values (A, B, A+B, A-B).
• IP20 rated for protection against dust and water.
• Compact and robust design.
• Multi-language interactive display.
• Selectable tension units on the display (N, kN, kg, lbs, N/m, kN/m, kg/m, pli).
• Maximum load memory and zero offset memory.
