Due to the increasing digitisation of production processes, the demands placed on digital data exchange between process valves and the programmable logic controller (PLC) are growing all the time. Ever larger volumes of process, device, and diagnostic data need to be transmitted to the superordinate controller.
To meet these requirements, the valve control head Type 8681 is now also available with the communication interface IO-Link or the Bürkert system bus (büS)/CANopen in addition to the variants with AS-i & DeviceNet.
Control heads are the links between the process valves at the field level and the system control. As part of decentralised automation concepts, they handle all pneumatic control, feedback, and diagnostic functions all the way to bus communication.
