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 make sure there is no unplanned actuation due to pressure peaks.

Key Features

• 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

Explosion Protection Safety Notes

• Voltage Hazards: Connect or disconnect terminals for 24 V power, SIA, EVS, and digital inputs only in a de-energized state in explosive atmospheres.
• Hot Swap Restrictions: The use of the Hot Swap function is strictly prohibited in explosive atmospheres unless it can be proven by suitable test equipment that no explosive atmosphere is present during the procedure.

Product Design and Assembly

Electronic Module with Digital Inputs (Optional)

The digital inputs are supplied (24 V) by the electronic module. Current is limited to maximum 30 mA per digital input. Standard 3-wire sensors and 2-wire sensors with voltages between 10…30 V as well as mechanical limit switches can be used.

Valves Type 6534 for Safety-Related Shut-Off, SIA Variant (Optional)

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. Manual override is not required for these valve variants. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.
