Burkert Type 8652 AirLINE valve island (SKU 20135047) 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.

This specific configuration features 8 valve ports, PROFINET S2 (System redundancy) communication, and an AirLINE Quick adapter made of aluminium. It supports a pressure range from vacuum to 10 bar and is suitable for ambient temperatures between -10 °C and 55 °C.

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.

Pneumatic connection	Stainless steel 1.4401 or Nickel-plated brass
Pneumatic Supply / Exhaust	Push-in D 10 mm, 3/8"
Pneumatic working ports	Push-in D 6 mm, 1/4"

Approvals and Conformities

• Explosion Protection: Optional ATEX / IECEx 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.

EX Safety Note

For explosion protection variants, the device must be installed in an enclosure complying with EN/IEC 60079-0 and EN/IEC 60079-7 (minimum IP54 for gas, IP6X for dust). The Hot Swap function is strictly prohibited in a present explosive atmosphere unless it can be proven that no explosive atmosphere is present during the operation.

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). The interface plate has a dedicated terminal to which the pneumatic valves' power supply is connected.

Fieldbus Interface

For Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) or PROFINET S2, the device uses X1 and X2 RJ45 interfaces.

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).

Module-Based Safety Shutdown (Optional)

Optional connections for module-based safety shutdown allow individual valve units to be switched off by connecting to a potential-free contact.
