ABB PFEA112‑20 3BSE050091R20is 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.Main SpecificationsBrand: ABBModel: PFEA112‑20, Part No.3BSE050091R20Product Type: Tension Control Amplifier ElectronicsInput: Dual‑channel for Pressductor load cell sensorsFieldbus: PROFIBUS‑DP communication interfacePower Supply: 24 VDC industrial power supplyMounting: Standard DIN rail installationDisplay: Local LCD screen with operation keypadCertification: UL, CE industrial compliance certificationOperating Temperature Range:‑10°C ~ 55°CCore FunctionsAcquire and condition weak measurement signals from ABB PFTL series tension load cellsReal‑time tension value calculation, support sum‑mode and difference‑mode measurement algorithmsAdjustable digital filter suppresses vibration and electromagnetic interference from production‑line environmentOutput analog control signals to drive brakes, clutches and servo actuators for constant‑tension closed‑loop controlPROFIBUS‑DP bus realizes tension data transmission and parameter interaction with upper‑level PLC/DCS systemLocal LCD display for on‑site parameter setting, tension value reading and alarm status checkingBuilt‑in fault diagnosis detects sensor breakage, signal loss and module hardware abnormalityDIN‑rail mounting structure facilitates installation and spare‑part replacement during on‑site maintenanceHigh measuring accuracy avoids web‑material wrinkling, stretching and breaking in winding‑unwinding processProvide core tension measuring and control hardware for web‑processing automation hardware stationApplication ScenariosPaper‑making production line web tension measuring and closed‑loop control cabinet configurationPrinting packaging industry film and paper winding‑unwinding tension‑control projectsTextile industry fabric processing equipment tension‑monitoring and regulation scenariosMetallurgy foil production line high‑precision tension‑measurement application projectsIndustrial renovation projects, tension‑amplifier replacement and production‑line system upgradeLegacy ABB Pressductor tension‑system spare‑parts replacement and field‑maintenance scenariosDIN‑rail cabinet spare‑parts backup for aged web‑processing industrial facilitiesABB tension‑measurement spare‑parts inventory and on‑site production‑line cabinet maintenance supporting projects
