Product Details

The PFSA140 3BSE006503R1 is tension measuring signal processing module for ABB PFS tension measurement system, widely used in paper‑making machine tension control application.

This module cooperates with PFTL series tension load cells, receives weak strain analog signals generated by sensor under roll force. It completes filtering, amplification and signal conditioning, converts strain signal into available digital measurement data, and transmits data to main controller via backplane bus.

It provides accurate tension value for paper web closed‑loop control, effectively prevents material deviation, breakage and other faults during high‑speed paper‑making production.

On‑board self‑diagnosis function can detect sensor disconnection, signal over‑range and module hardware failure, output corresponding fault alarm information.

Conformal coated circuit board resists dust and moisture, adapts to humid working environment of paper mill workshop.

Standard rack plug‑in structure supports convenient on‑site maintenance and replacement.

Widely applied in papermaking production line renovation and maintenance projects.

It is important spare hardware for tension control loop debugging and defective PFSA140 module replacement.
