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. 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.

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

Circuit function	Description
C (CF C)	3/2-way solenoid valve, servo-controlled, with manual override, normally closed
D (CF D)	2 × 3/2-way solenoid valve, servo-controlled, with manual override, normally open
H (CF H)	5/2-way solenoid valve, servo-controlled, with manual override. Pressure applied via port (1), therefore one of the two ports (2) or (4) is under pressure.
L (CF L)	5/3-way solenoid valve, with manual override, in middle position all ports locked
M (CF M)	5/3-way solenoid valve, servo-controlled, with manual override, in middle position ports 2 and 4 ventilated
N (CF N)	5/3-way solenoid valve, with manual override, in middle position ports 2 and 4 exhausted
Z (CF Z)	5/2-way solenoid valve, impulse variant with 2 coils and manual override

Approvals and Conformities

• Explosion protection: ATEX / IECEx Zone 2 (II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc)
• North America: UL Listed for USA and Canada, UL Recognized for Hazardous Locations
• Others: China Compulsory Certification (CCC)

Explosion Protection Safety Notes

• Danger from voltage: Connect or disconnect terminals only in a de-energized state in explosive atmospheres.
• Electrostatic charge: 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.
• Hot Swap: The use of the hot swap function is not permitted in a present explosive atmosphere.

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.

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.

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.
