ABB PFEA112‑20 3BSE050091R20 Pressductor Tension Measuring Electronics Module

The ABB PFEA112‑20 (3BSE050091R20) is a DIN‑rail mounted tension measuring electronics unit for Pressductor magneto‑elastic load cells. It receives weak sensor signals from ABB PFTL/PFCL series tension transducers, calculates real‑time web‑tension value and outputs analog control signals for closed‑loop tension regulation in web‑processing production lines.

This module is equipped with local LCD display and operation keypad for on‑site parameter configuration and value reading. Profibus‑DP interface enables data exchange with PLC/DCS systems for remote monitoring and parameter download. Widely used as aftermarket spare‑part for paper‑mill, film‑coating, printing and metal‑foil rolling‑line control‑cabinet overhaul, sensor‑loop debugging and system retrofitting projects.
