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.

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.

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

Supports Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) or PROFINET S2 via RJ45 interfaces, as well as PROFIBUS DP and CANopen/büS.

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 (Terminal 1 = valve unit 1, Terminal 2 = valve unit 2, etc.). Connect the connection to a potential-free contact (mechanical switch or relay).

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.

Safety Instructions for Hazardous Areas

WARNING

Danger from voltage:

• In an existing explosive atmosphere, the connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.
• The Hot Swap function is prohibited in an existing explosive atmosphere unless it can be proven and ensured by suitable test equipment that no explosive atmosphere is present for a certain period.

Danger of explosion due to electrostatic charge:

• Take appropriate measures to ensure that no electrostatic charge can occur in the potentially explosive area.
• Only clean the device surfaces by wiping them gently with a damp or antistatic cloth.
