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. Installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability; for instance, check valves in the exhaust air ducts make sure there is no 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, making 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 circuit functions using Type 6534 solenoid valves:

• Circuit function C (CF C): 3/2-way solenoid valve, normally closed.
• Circuit function D (CF D): 2 × 3/2-way solenoid valve, normally open.
• Circuit function H (CF H): 5/2-way solenoid valve.
• Circuit function L (CF L): 5/3-way solenoid valve, in middle position all ports locked.
• Circuit function M (CF M): 5/3-way solenoid valve, in middle position ports 2 and 4 ventilated.
• Circuit function N (CF N): 5/3-way solenoid valve, in middle position ports 2 and 4 exhausted.
• Circuit function Z (CF Z): 5/2-way solenoid valve, impulse variant with 2 coils.

SIA Variant (for safety-related shut-off)

Type 6534 valves (SIA variant) 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).

Approvals and Conformities

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).

Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) or PROFINET S2: Interface X1 and X2 RJ45 (Pin 1: TX+, Pin 2: TX-, Pin 3: RX+, Pin 6: RX-).

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.

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.

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 Locations

When using the device in explosion-hazard areas, the following safety instructions must be observed:

Danger caused by voltage

• Disconnect the power before working on the device or system. Prevent it from being switched back on.
• In an existing explosive atmosphere, connection terminals for 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is disconnected.
• The Hot Swap function is prohibited in an existing explosive atmosphere.

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 surface by wiping it gently with a damp or antistatic cloth.

Special conditions for safe use

• For explosion protection type "ec", install the device in an enclosure that meets the requirements of EN/IEC 60079-0 and EN/IEC 60079-7 with a degree of protection of at least IP54.
• For explosion protection type "tc" (dust), install the device in an enclosure with a degree of protection of at least IP6X.
• Only use the device in an area with a degree of pollution of at least 2 as defined in IEC 60664-1.
