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

Approvals and Conformities

• Explosion protection: Optional as a category 3 device suitable for zone 2/22. ATEX: II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc. IECEx: Ex ec IIC Gc / Ex tc IIIC Dc.
• 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, Div 2).
• China Compulsory Certification (CCC): Optional for products with Ex approval suitable for import and use for hazardous applications in China.

Voltage Hazard in Explosive Atmospheres

Disconnect power before working on the device or system. In current explosive environments, connection terminals for 24 V power supply, SIA, EVS, and digital inputs must only be inserted or removed in a de-energized state.

Hot Swap Restriction

The Hot Swap function is prohibited in current explosive environments unless it can be proven and ensured with suitable testing equipment that no explosive atmosphere is present during the procedure.

• White: CAN_H (büS connection)
• Green: SHIELDING
• Blue: CAN_L (büS connection)
• Black: GND

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.

Valves Type 6534 for safety-related shut-off, SIA variant (optional)

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).

Example Configuration
