Product Details

The PFEA111‑20 3BSE050090R20 is compact DIN‑rail‑mounted IP20 tension electronics unit of ABB Pressductor tension measurement system.

This PFEA111‑20 unit supports two‑channel strain‑gauge tension sensor input, designed for installation inside control cabinet.

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

It supports sum and difference tension calculation for dual‑sensor measuring points, signal transmission depends entirely on analog output without field‑bus communication function.

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 installation structure saves cabinet space, convenient for on‑site maintenance and replacement.

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 PFEA111‑20 unit replacement.
