Control Valve Interface
The DVC6200 digital valve controller is mechanically attached to the valve’s actuator by means of a mounting bracket.
The control valve's position is conveyed to the travel sensor of the DVC6200 digital valve controller by means of the
feedback bracket and magnet assembly attached to the actuator’s stem.

Pneumatic tubing connected to the DVC6200 brings instrument supply air to the DVC6200 and takes controlled
output air from the DVC6200 to the actuator. Pressure sensors in the DVC6200 measure these pressure signals and
present them as device variables
Host interface
The input to the DVC6200 can either be twowire 4to20 mA current loop (in pointtopoint mode) or 24 VDC (in
multidrop mode). This input is connected in the DVC6200’s terminal box on two terminals marked “LOOP +” and
“LOOP ”. Refer to the DVC6200 Series quick start guide for connection details.
Pushbutton Calibration
A pushbutton near the wiring terminals in the terminal box provides a quick means to autocalibrate the travel of the
instrument. The button must be pressed for 3 to 10 seconds. Autocalibration will move the valve through the full
range of travel whether the Instrument Mode is In Service or Out of Service. However, if the Write Protection is
Protected, this button will not be active. To abort, press the button again for 1 second. The calibration button is
disabled by default.
