Burkert 8652 AirLINE valve island is developed for process automation requirements. Diagnostic functions are visualised on the LC display in clear text and symbols, simplifying message allocation 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 or on a standard rail. Key pneumatic functions, such as check valves in the exhaust air ducts, prevent unplanned actuation due to pressure peaks.

AirLINE Quick Adapter

The AirLINE Quick adapter reduces the use of components in the control cabinet by adapting the valve terminal directly to the control cabinet floor or wall. This reduces space requirements and installation effort due to hose connections directly at the bottom of the control cabinet.

WARNING

CANopen requires two terminating resistors: one at the beginning of the network and one at the end. The resistance between CAN_H and CAN_L when the power is switched off should be approximately 60 Ω.

Product Design and Assembly

Electronic Module with Digital Inputs

The digital inputs are supplied (24 V) by the electronic module. Current is limited to a maximum of 30 mA per digital input. Standard 3-wire sensors, 2-wire sensors (10–30 V), and 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, allowing a valve circuit to be interrupted by an external switch. 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 AirLINE Type 8652 Industrial Ethernet variant as the master valve terminal and various AirLINE Type 8652 büS variants as slave valve terminals.
