BURKERT 20117181 (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; for instance, check valves in the exhaust air ducts make sure there is no unplanned actuation due to pressure peaks. The system supports safety-related shut-off of valves, higher plant availability with PROFINET S2 (system redundancy), and includes EX-variants for ATEX / IECEx Zone 2, CCC, and cURus HazLoc CL I, II, III Div 2.

• 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

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. To use the switch-off function, connect the connection to a potential-free contact.

Electrical data	Description
Connection	Pluggable spring-loaded terminal, 12-pin. Conductor cross-section 0.14 mm²...1.5 mm² (AWG 26...16)
Required switching capacity	1.5 A / 24 V DC

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.
