ABB PFSK151 (3BSE018876R1) PROFIBUS-DP

ABB PFSK151 with material number 3BSE018876R1 is a dedicated fieldbus communication expansion module for ABB AC800M controller under System 800xA distributed control platform. 

It works as PROFIBUS-DP slave gateway, realizing high-speed cyclic data exchange between AC800M CPU and external PROFIBUS-DP master hosts, third-party PLC, variable frequency drives, 

remote I/O stations and intelligent field instruments.

This module plugs into the CPU base unit expansion slot, processes protocol packaging, data buffering and signal isolation independently to reduce main CPU communication load. It supports 

standardized PROFIBUS-DP cyclic input/output data transmission, diagnosis message upload and bus fault monitoring. With complete electrical isolation design between internal controller bus 

and field bus side, it effectively suppresses ground loop interference and surge damage. It is a key spare part for communication expansion, bus fault maintenance and system retrofit in petrochemical, 

power, metallurgy and water treatment automation projects.
