VP200 |
YOKOGAWA VP200 Current-to-Pneumatic Valve Positioner
The VP200 current-to-pneumatic valve positioner converts a 4 to 20mA DC or 10-50mA DC signal to a pneumatic signal for control valve actuation.
The VP200 current-to-pneumatic positioner receives control signals from electronic controllers or a DCS and converts these to pneumatic signals. It is a dedicated positioner for control valves that actuates pneumatic type control valves, as well as gives feedback on the valve stem position.
