PN16
Burkert Type 8652 AirLINE valve island (SKU 20120520) is developed for process automation requirements. Diagnostic functions can be visualised on the LC display in clear text and symbols, simplifying the assignment of messages and saving time during start-up and maintenance. Diagnostic messages are also available at the controller for a fast overview of the plant status. The hardware is optimised for installation at the bottom of the control cabinet, with standard rail installation also possible. Key pneumatic functions, such as check valves in the exhaust air ducts, 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.
- Enables the use of more compact control cabinets.
- Reduced installation effort due to hose connections directly at the bottom of the control cabinet.

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).
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.
