ABB PFEA112-20 3BSE030369R0020 Precision Tension Electronic Control

ABB PFEA112-20 with part number 3BSE030369R0020 is a high-precision tension measuring and control electronic unit belonging to ABB Pressductor series. 

It receives signals from two tension load cells, processes tension data with built-in high-speed algorithm, and outputs analog signals or transmits data via Profibus-DP 

bus to upper PLC/DCS systems for closed-loop tension regulation. It is widely adopted as original replacement spare part for web tension control equipment maintenance in 

winding and unwinding production lines.
