Foundation Fieldbus Valve Positioner

The FY302 is from the first generation of Fieldbus devices. It is a control valve positioner for pneumatic valve in a Fieldbus system. The FY302 produces a pressure output as required to position a control valve according to an input received over the Fieldbus network or internal controller.

The Fieldbus technology used in the FY302 enables, an easy interface between the field and the control room and several interesting features that considerably reduce the installation, operation and maintenance costs.
