Introduction to ABB PFEA111-20 3BSE050090R20
The ABB PFEA111-20 (order number: 3BSE050090R20) is a high-precision tension control module, renowned as the “tension stability guardian” for web processing industries such as papermaking, metal processing, and packaging. As a core product in ABB’s Tension Electronics series, it integrates advanced signal processing algorithms and user-friendly configuration functions, specializing in receiving signals from two load cells (e.g., ABB PFTL/PFCL series) to calculate tension deviations and output control signals for actuators. This module ensures consistent tension during material winding, unwinding, and conveying processes, effectively preventing defects like material breakage, wrinkles, and uneven thickness. Widely applied in stainless steel cold rolling, lithium battery diaphragm coating, and paper machine production lines, its industrial-grade design features IP20 protection (IP65 optional) and strong anti-EMC interference capability, enabling stable operation in harsh environments with temperature fluctuations from -20°C to +60°C.
