ABB PFEA112‑20 3BSE050091R20 Tension Control Amplifier

ABB PFEA112‑20 (3BSE050091R20) is a high‑precision Pressductor tension control amplifier module. It receives measuring signals from ABB PFTL series tension load cells, performs signal conditioning and real‑time tension calculation, and outputs analog control signals for constant tension closed‑loop regulation for web‑processing equipment.

This DIN‑rail mounted unit is equipped with local LCD display and operation keys, supports PROFIBUS‑DP fieldbus communication. It features adjustable digital filter and channel fault diagnosis. Widely used as replacement spare‑parts for paper‑making, printing, textile and metallurgy production‑line maintenance and retrofit projects.
