BURKERT 20117611 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; for instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks.

Key features include:

• Safety-related shut-off of valves possible (SIA variant)
• 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

Product properties
AirLINE Quick Adapter Plate	Stainless steel 1.4301 / Anodised aluminium
Pneumatic connection	Stainless steel 1.4401 / Nickel-plated brass
Valve functions per station	8, 16, 24, 32, 40 and 48
Pneumatic Supply / Exhaust	Push-in D 10 mm, 3/8"
Pneumatic working ports	Push-in D 6 mm, 1/4"

Circuit Functions

The valve island supports various standard circuit functions including CF C (3/2-way normally closed), CF D (3/2-way normally open), CF H (5/2-way), CF L (5/3-way all ports locked), CF M (5/3-way ports 2 and 4 ventilated), CF N (5/3-way ports 2 and 4 exhausted), and CF Z (5/2-way impulse).

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.

Product Connections

Connection Notes

• Connect 5-pin spring-loaded terminal for communication and displays according to the pin assignment (Red: 24 V DC, Black: GND).
• The interface plate has a 2-pin spring-loaded terminal to which the pneumatic valves' power supply is connected (Red: AUX 24 V, Black: GND).
• Possible cable cross-section: ≤ 1.5 mm².

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

Danger from Voltage and Electrostatic Charge

• Disconnect the power supply before working on the device or system. Prevent it from being switched on again.
• 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 is prohibited in an existing explosive atmosphere.
• Sudden discharge of electrostatically charged devices or persons can cause an explosion in the potentially explosive area. Ensure that no electrostatic charge can build up.

Special Conditions for Safe Use

• Install the device in an enclosure suitable for the type of protection "ec" according to EN/IEC 60079-0 and EN/IEC 60079-7, with a degree of protection of at least IP54.
• For type of protection "tc" (dust), install in an enclosure with a degree of protection of at least IP6X.
• Ensure that the set value of the transient protection does not exceed 140% of the rated peak voltage at the supply terminals of the device.
