DVC2000 Digital Valve Controller
September 2017
Product Interfaces
Control Valve Interface
The DVC2000 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 DVC2000 digital valve controller by means of the
feedback bracket and magnet assembly attached to the actuator's stem or rotating travel sensor.
Pneumatic tubing connected to the DVC2000 brings instrument supply air to the DVC2000 and takes controlled
output air from the DVC2000 to the actuator. A pressure sensor in the DVC2000 measures the pressure signal and
presents it as a device variable.
Host interface
The input to the DVC2000 can either be twowire 4to20 mA current loop (in pointtopoint mode). This input is
connected in the DVC2000's terminal box on two terminals marked "LOOP +" and "LOOP ". Refer to the DVC2000
quick start guide for connection details.
