Product Details

The PFEA112‑20 3BSE050091R20 is compact DIN‑rail‑mounted tension electronics unit of ABB Pressductor tension measurement system.

This PFEA112‑20 unit supports two‑channel strain‑gauge tension sensor input, designed for cabinet installation.

It amplifies weak tension sensor signals and converts them into standard analog signals for PLC, drive and upper automation system.

Profibus‑DP communication interface supports remote parameter configuration and real‑time tension data transmission.

Built‑in multi‑language LCD display and operation keys allow local reading of tension value, parameter adjustment and fault status check.

Digital filtering function effectively suppresses field interference and improves measuring stability for high‑speed web production lines.

Built‑in hardware self‑diagnosis function can detect sensor breakage, cable fault and module internal abnormality, and trigger alarm output.

Compact DIN‑rail structure saves cabinet space, convenient for installation and maintenance.

Widely applied in papermaking, plastic film, textile, printing and metal foil processing industries.

It is important spare hardware for web tension system renovation, sensor signal debugging and defective PFEA112‑20 unit replacement.
