The Burkert Type 8652 AirLINE valve island has been especially developed for process automation requirements. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller, enabling a fast overview of the plant status. The hardware is optimised for installation at the bottom of the control cabinet. Installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts that prevent unplanned actuation due to pressure peaks.

• Safety-related shut-off of valves possible
• Higher plant availability with PROFINET S2 (system redundancy)
• Process reliability through pneumatic functions
• Optimised for installation at the bottom of the control cabinet
• EX-variants: ATEX / IECEx Zone 2, CCC, cURus HazLoc CL I, II, III Div 2

AirLINE Quick

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall.

Advantages:

• Reduced space requirement in the control cabinet
• Makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Product Design and Assembly

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.

Safety Instructions for Potentially Explosive Areas

Voltage Hazard

• Before working on the device or system, disconnect the power supply. Secure against reactivation.
• In an existing explosive atmosphere, the connection terminals for 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.
• The use of the Hot Swap function in an existing explosive atmosphere is prohibited.

Electrostatic Charge Hazard

Sudden discharge of electrostatically charged devices or individuals can cause an explosion in the potentially explosive area.

• Take appropriate measures to ensure that no electrostatic charge can build up in the potentially explosive area.
• Clean the device surface only by wiping it gently with a damp or antistatic cloth.

Special Conditions for Hot Swap

The use of the Hot Swap function in an existing explosive atmosphere is prohibited. If it can be proven and ensured by means of suitable test equipment that no explosive atmosphere is present for a certain period of time, it is permissible to remove/insert valves using Hot Swap during this time. The Hot Swap function may only be used by appropriately trained personnel.
