ABSTRACT:
An electropneumatic regulator system, which has an electropneumatic regulator for controlling a pressure and a flow rate of a fluid supplied from a fluid source on the basis of a level of an input signal, comprises a communication unit for making communication with a master station, and a control unit for controlling the electropneumatic regulator in response to at least the contents of communication data received by the communication unit. Accordingly, it is possible to collectively control one or more electropneumatic regulators by using, for example, the master station on the basis of the communication so that the response performance can be improved for the remote control of the electropneumatic regulators, and the cost can be reduced.
