Burkert Type 8652 AirLINE is a valve island 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. The system supports safety-related shut-off of valves and offers higher plant availability with PROFINET S2 (system redundancy).

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 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).

Fieldbus Interfaces

• CANopen/büS: 5-pin spring terminal.
• Industrial Ethernet: PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic or PROFINET S2 via RJ45 interfaces X1 and X2.
• PROFIBUS DP: D-Sub socket 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. 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

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

Voltage Hazard

• Before working on the device or system, disconnect the power supply and secure against reactivation.
• In an existing explosive atmosphere, 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.

Electrostatic Charge

• Sudden discharge of electrostatically charged devices or individuals can cause an explosion in hazardous areas.
• Take appropriate measures to prevent electrostatic charging in the hazardous area.
• Clean device surfaces only by gently wiping them with a damp or antistatic cloth.

Special Conditions for Hot Swap

The Hot Swap function is prohibited in an existing explosive atmosphere. If it can be proven and ensured by suitable test equipment that there is no explosive atmosphere for a certain period of time, it is permissible to remove/insert valves using Hot Swap during this time.
