Product Details

The PFEA112‑65 3BSE050091R65 is field‑mount IP65 tension electronics unit of ABB Pressductor tension measurement system.

This PFEA112‑65 unit supports two‑channel strain‑gauge tension sensor input, designed for direct installation on production equipment instead of inside control cabinet.

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.

IP65 rugged housing resists dust and moisture on workshop site, no extra protective cabinet is required.

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 PFEA112‑65 unit replacement.
