FY303
Profibus PA Valve Positioner
The FY303 is a control valve positioner for PROFIBUS systems. The FY303 provides a pressure output to position the control valve according to input received from a PROFIBUS network. The digital technology used in the FY303 enables an easy interface between the field and the control room including special features that considerably reduce installation, operation and maintenance costs.
It can be configured using commercially available Profibus-PA compatible programs or locally using a magnetic tool in basic operations.
The FY303 is designed according to Profile V3.0
