BURKERT 338636 Type 8652 is a 16-bank valve island 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. Moreover, key pneumatic functions ensure increased process reliability, such as check valves in the exhaust air ducts that 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 wall.

Advantages:

• 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

Approvals and Conformities

• Explosion protection: ATEX (BVS 20 ATEX E 031 U), IECEx (IECEx BVS 20.0024 U)
• North America: UL Listed, UL Recognized for Hazardous Locations
• Others: China Compulsory Certification (CCC)

Product Installation

Installation Situation Inside the Control Cabinet

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).
