The FY303 is a control valve positioner for pneumatic valve in a PROFIBUS system. It produces a pressure output as required to position a control valve according to input received over the PROFIBUS network or internal controller.
The PROFIBUS PA technology used in the FY303 enables an easy interface between the field and the control room and also includes several interesting features that considerably reduce the installation, operation and maintenance costs. The FY303 is part of Smar's complete 303 series of PROFIBUS PA devices.
