Product physical display
In addition to the traditional function of converting an input current signal (4 to 20 mA) to a
pneumatic output pressure, the DVC2000 digital valve controller communicates via a local
display panel and/or via the HART® protocol. An option is available which provides isolated
circuitry for two (2) integrated limit switches (for open/close valve indication) and a valve
position transmitter (for separate valve position feedback).
