Combining Bürkert Pneumatic Actuation with leading modular distributed I/O field hardware, AirLINE puts consumers in control of large-scale industrial automation installations. Bürkert Fluid Control Systems is raising awareness of a comprehensive process automation solution that creates a remote field I/O network which is compact, reliable and not exclusive to any specific communication protocol. And with considerable engineering efficiencies achieved, Bürkert customers are saving up to 40 per cent on total automation systems costs.
Designed for maximum flexibility, AirLINE is unique in allowing Rockwell's Point I/O modules, Siemens ET200S modules, Phoenix Inline I/O modules or Wago I/O System 750 modules to be combined with the high-performance Bürkert solenoid valve units mounted on a single DIN rail assembly.
Caption 1: Schematic of a system automated by Bürkert Fluid Control Systems using distributed field I/O hardware. The series 8644 remote process actuation and control system combines digital I/O, including a full complement of pneumatic outputs, analogue I/O, including direct RTDs and T/Cs, and specialty signals (RS232, High Speed counters, etc) in a single node. By developing this system, facilitating the entire I/O requirement to a single node, Bürkert has resolved the single most limiting (and costly) factor in the use of I/O networks.
All components of the AirLINE are modular, allowing enclosures to be easily customised to specific requirements of size, flow and switching function. Fieldbus connectivity is made via customer-defined standard industrial fieldbus communications.
"Partnering with industry leaders Rockwell, Siemens, Phoenix and Wago has given Bürkert's AirLINE automation system a unique capability in the Australian market," said National Sales Manager Mr David Booysen.
"Instead of developing our own control system to force onto customers, we forged alliances with industry experts producing market leading I/O systems - we add our world-class solenoids, process valves and sensors, building and automating comprehensive systems solutions that can span hectares.
"Bürkert adapts itself to the customer's needs and to the systems already in place, rather than straight-jacketing customers with limited options and alternatives," said Mr Booysen.
"Bürkert realised that there was no need to reinvent the wheel, and it has been a major point of interest for clients of the calibre of Orica," he said.

The AirLINE 11 mm- and 16 mm-wide solenoid pilot valves are available in 3/2, 5/2, 5/3 standard and 5/2 latching functions. The system handles flow rates from 180 to 700 liters per minute, with a pressure range of 2 to 10 Bar. Bürkert's pilot coil rocker technology requires low power consumption and handles high cycle rates at no detriment to coil life.Importantly, the rocker coil multi-port seat valves operate with a servo piston function with self readjusting seats. Unlike spool valves, seat valves do not rely on friction to operate and therefore no sticking problems occur after hours of rest. Mechanical manual override function and integral metric push in fitting connection comes standard at no extra cost.

"AirLINE has introduced numerous original concepts to the process control industry, providing significant cost saving to engineering," he said.
"The system enables pneumatic 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" said Mr Booysen.
"Combining lead supplier I/O modules and Bürkert pneumatic actuation in the same unit provides significant benefits including easier design and installation, less cabinet space, weight and lower total costs. The Bürkert system is suited to systems and processes in water treatment, transportation and automotive, food and beverage manufacture including dairy and viticulture, pharmaceuticals and biotechnology, semiconductor manufacturing, cosmetics, pulp and paper processing, chemicals, textile dyeing and drying equipment. With a global network spanning offices in more than 40 countries, and operational outposts in an additional 80, Bürkert Fluid Control Systems is an established and mature global organisation celebrating its 60th Anniversary in 2006. Mr David Booysen, National Sales Manager of Bürkert Fluid Control Systems in Australia, has worked in process automation for more than twenty years.
