Flexible control system cuts standardisation costs

A Burkert Fluid Control Systems product story
Edited by the Engineeringtalk editorial team Feb 27, 2008

8644 provides users with a remote field I/O network which is compact, reliable and not exclusive to any specific communication protocol.

Burkert's AirLine Type 8644 remote process actuation and control system overcomes plant standardisation and communication protocol issues by integrating Burkert high-performance solenoid valves with analogue and digital I/O modules and fieldbus communications from all market-leading PLC vendors, including Siemens, Rockwell, GE Fanuc, Bosch, Beckhoff, Phoenix Contact, Wago and Hitachi.

Calculated to save up to 40% on total system costs through the engineering efficiencies achieved, the series 8644 provides users with a remote field I/O network which is compact, reliable and not exclusive to any specific communication protocol.

The remote process actuation and control system combines digital I/O, including a full complement of solenoid pilot valve outputs, digital and analogue I/O, including direct RTDs and T/Cs and speciality signals into a single node.

The system enables pneumatic solenoid valves to be electrically connected directly to a remote I/O module, without any individual coil wiring, numbering or termination required.

Each valve is simply a digital output addressed by the network.

All components of the AirLine 8644 are modular, allowing enclosures to be easily customised to specific requirements of size, flow and switching function.

Moreover, fieldbus connectivity, including DeviceNet and Profibus, is provided via customer-defined standard industrial fieldbus communications.

The Burkert AirLine supports virtually any process field device, pneumatic or electronic.

The system's modular construction permits configuration of customised and pre-mounted/pre-tested solutions that are suitable for applications where flexibility and low cost are of importance.

Depending upon the application, the system can incorporate up to 13 modules (2x and 8x module types), with a maximum of 64 valves accepted.

The AirLine 11 and 16mm-wide solenoid pilot valves are available in 3/2, 5/2, 5/3 standard and 5/2 latching functions.

These valves offer flow rates from 180 to 700 litres per minute.

They incorporate Burkert's rocker technology, which permits them to handle pressures of up to 10bar while maintaining fast response times and minimising power consumption.

In addition, rocker technology enables higher valve cycle life to be achieved.

The Burkert 8644 system is suited to systems and processes in water treatment, transportation and automotive, food and beverage manufacture, pharmaceuticals and biotechnology, semiconductor manufacturing, cosmetics, pulp and paper processing, chemicals, textile dyeing and drying equipment.
