DVC6200 SIS Digital Valve Controller

August 2014

Product Interfaces

Control Valve Interface

The DVC6200 SIS digital valve controller is mechanically attached to the valve’s actuator by means of a mounting

bracket. The valve's position is conveyed to the travel sensor of the DVC6200 SIS digital valve controller by means of

the feedback bracket and magnet assembly attached to the actuator’s stem.

Pneumatic tubing connected to the DVC6200 SIS brings instrument supply air to the DVC6200 SIS and takes

controlled output air from the DVC6200 SIS to the actuator. Pressure sensors in the DVC6200 SIS measure these

pressure signals and present them as device variables

Host interface

The input to the DVC6200 SIS can either be twowire 4to20 mA current loop (in pointtopoint mode) or 24 VDC (in

multidrop 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.
