PN16
BURKERT 20114066 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. It supports safety-related shut-off of valves and offers higher plant availability with PROFINET S2 (system redundancy).

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.
Explosion Protection Safety Instructions
DANGER
Danger from electrical voltage in potentially explosive atmospheres:
- Disconnect the power supply before working on the device or system. Secure against reactivation.
- In an existing explosive atmosphere, the connection terminals for 24 V power supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when de-energized.
- The use of the Hot Swap function is prohibited in an existing explosive atmosphere.
WARNING
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 minimum protection degree of IP54.
- For explosion protection type "tc" (dust), install the device in an enclosure that meets the requirements of EN/IEC 60079-0 and EN/IEC 60079-31 with a minimum protection degree of IP6X.
- Only use the device in an area of at least pollution degree 2 as defined in IEC 60664-1.
- Ensure that the transient protection is set to a value not exceeding 140% of the peak rated voltage value at the supply terminals to the equipment.
