The BURKERT 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. This, therefore, enables 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, of course, also possible. Moreover, key pneumatic functions ensure increased process reliability. For instance, check valves in the exhaust air ducts 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
• This makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Circuit Functions

The Type 8652 supports various standard circuit functions including 3/2-way (CF C, CF D), 5/2-way (CF H, CF Z), and 5/3-way (CF L, CF M, CF N) solenoid valves.

SIA variant (for safety-related shut-off): 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).

Product Installation

To use the Hot Swap function, always observe a minimum distance to the front edge of the control cabinet when installing the valve island inside the control cabinet.

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 EX Areas

Special conditions for use in potentially explosive areas

• The device must be installed in an enclosure that meets the applicable requirements for explosion protection type "ec" according to EN/IEC 60079-0 and EN/IEC 60079-7, with a degree of protection of at least IP54.
• For explosion protection type "tc" (dust), the enclosure must meet EN/IEC 60079-0 and EN/IEC 60079-31 with a degree of protection of at least IP6X.
• The device may only be used in an area with a pollution degree of at least 2 as defined in IEC 60664-1.
• Ensure that the transient protection is set to a value not exceeding 140% of the peak rated voltage at the supply terminals to the equipment.
• In a potentially explosive atmosphere, 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 is prohibited in a potentially explosive atmosphere unless it can be proven and ensured by suitable test equipment that no explosive atmosphere is present for a certain period of time.
