Burkert 20065535 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 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 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.

• 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

The valve island supports various standard circuit functions and SIA variants for safety-related shut-off.

• Standard Functions: Circuit functions C (3/2-way), D (2x 3/2-way), H (5/2-way), L (5/3-way), M (5/3-way), N (5/3-way), Z (5/2-way impulse).
• SIA Variant: Circuit functions C, H, L (servo-controlled, without manual override) designed for safety-related shut-off.

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 (UL 61010-1) and UL Recognized for Hazardous Locations (Class I, Zone 2; Class II, Zone 22; Class I, Div 2).
• Others: China Compulsory Certification (CCC) for hazardous applications.

Safety Instructions for EX Areas

• Danger from voltage: Disconnect power before working on the device. In explosive atmospheres, connection terminals for 24 V supply, SIA, EVS, and digital inputs must only be plugged in or unplugged when de-energized.
• Hot Swap: The Hot Swap function is prohibited in explosive atmospheres unless it is ensured that no explosive atmosphere is present.
• Electrostatic charge: Take appropriate measures to ensure no electrostatic charge occurs in the potentially explosive area. Clean surfaces only with a damp or antistatic cloth.

Dimensions

Variant 4-, 8- and 12-fold

Variant 16-, 20- and 24-fold

Product Connections

• Power supply for communication and displays: 5-pin spring-loaded terminal (24 V DC, CAN_H, Shielding, CAN_L, GND).
• Power supply for 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 via RJ45; PROFIBUS DPV1 via D-Sub 9-pin.

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)

Type 6534 valves are equipped with additional connection terminals. A valve circuit can therefore be interrupted by an external switch. To use the shut-off function, connect the terminal to a potential-free contact (mechanical switch or relay).
