Product Description: The PFEA111-20 is a tension electronics module designed for measuring and monitoring tension in web materials (such as paper, film, and textiles) or for force measurement in various industrial processes. It is part of ABB’s web tension measurement systems. This module typically interfaces with load cells to provide accurate tension readings and outputs for process control and operator instrumentation. It often features a digital display for showing tension values and configuration keys for parameter settings.  

Product Parameters (Typical):

• Inputs: 2 load cells
• Outputs:
  • Voltage and current (A+B) with adjustable filtering
• Display: Shows tension values (A, B, A+B, A-B)
• Power Supply: Typically DC 24 V (18 – 36 V)  
• Power Requirement: Typically 7.5 W
• Load Cell Excitation: 0.5 A rms, 330 Hz
• Analog Outputs: 1 (voltage or current selectable)
  • -5 – +11V (max. load 5 mA)
