DVC6000 Series FIELDVUE digital valve
Controllers (figures 1 and 2) are communicating.microprocessor-based current-to-pneumatic instruments. In addition to the traditional function ofconverting a current signal to a valve-positionpressure signal, DVC6000 Series digital valve controllers, using HART s communications protocol,give easy access to information critical to processoperation. This can be done using a Model 375
FieldCommunicator at the valve or at a field junction box,or by using a personal computer or a systemconsole within the control room. Using HARTcommunication protocol, information can be integrated into a control system or receivedon asingle loop basis.
DVC6000 Series digital valve controllers can beused on single- or double -acting actuators. The digital valve controller receives feedback of the valvetravel position plus supply and actuator pneumaticpressure. This allows the instrument to diagnose
