ABSTRACT:
An electropneumatic control device having a plurality of valves, each valve being associated with at least one electrically actuatable valve drive. Each valve drive has integrated therein its own bus communication unit and is coupled to a bus line for communication with a central control unit. Actuating control signals are supplied from the central control unit for controlling each of the plurality of valves integrated therein. The valve drives may also include electrical contacts for piercing an insulating sheath of the bus line to make electrical connection with control wires within the bus line. The electropneumatic control device described above reduces design complexity.
