BURKERT 20127386 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, though 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.

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, Normally closed
D (CF D)	2 × 3/2-way solenoid valve, Servo-controlled, Normally open
H (CF H)	5/2-way solenoid valve, Servo-controlled, Pressure applied via port (1)
L (CF L)	5/3-way solenoid valve, In middle position all ports locked
M (CF M)	5/3-way solenoid valve, In middle position ports 2 and 4 ventilated
N (CF N)	5/3-way solenoid valve, In middle position ports 2 and 4 exhausted
Z (CF Z)	5/2-way solenoid valve, Impulse variant with 2 coils

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).

Approvals and Conformities

• Explosion protection: Optional ATEX/IECEx (II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc). As a category 3 device suitable for zone 2/22.
• North America (USA/Canada): Optional UL Listed (UL 61010-1) and UL Recognized for Hazardous Locations (Class I, Zone 2; Class II, Zone 22; Class I, Division 2).
• China Compulsory Certification (CCC): Optional CCC for hazardous applications in China.

Explosion Protection Safety

For Ex protection type "ec", install the device in an enclosure complying with EN/IEC 60079-0 and EN/IEC 60079-7 with a degree of protection of at least IP54. Do not use the Hot Swap function in a present explosive atmosphere unless it is ensured that no explosive atmosphere is present during the procedure.

Product Connections

Power Supply

• Communication and displays: 5-pin spring-loaded terminal (24 V DC, CAN_H, SHIELDING, CAN_L, GND).
• Pneumatic valves: 2-pin spring-loaded terminal (AUX 24 V, GND).

Fieldbus Interface

Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) or PROFINET S2 – Interface X1 and X2 RJ45.

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 as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.
