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, 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.

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

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. A special SIA variant is available for safety-related shut-off, where valves are equipped with additional connection terminals allowing the valve circuit to be interrupted by an external switch.

Approvals and Conformities

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

Safety Instructions for EX Zones

When using the device in a potentially explosive atmosphere, the connection terminals for the 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is switched off. The Hot Swap function is prohibited in a present explosive atmosphere unless it can be proven that no explosive atmosphere is present during the procedure.

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. The module provides open-circuit detection with 2-wire sensors and short-circuit detection with 3-wire sensors.

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.
