BURKERT 361452 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. The system supports safety-related shut-off of valves and offers higher plant availability with PROFINET S2 (system redundancy).

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.

Advantages:

• 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

Circuit Functions

The Type 8652 supports various standard circuit functions (CF) including:

• CF C: 3/2-way solenoid valve, servo-controlled, normally closed.
• CF D: 2 × 3/2-way solenoid valve, servo-controlled, normally open.
• CF H: 5/2-way solenoid valve, servo-controlled.
• CF L: 5/3-way solenoid valve, in middle position all ports locked.
• CF M: 5/3-way solenoid valve, in middle position ports 2 and 4 ventilated.
• CF N: 5/3-way solenoid valve, in middle position ports 2 and 4 exhausted.
• CF Z: 5/2-way solenoid valve, impulse variant with 2 coils.

An SIA variant is also available for safety-related shut-off, where valves are equipped with additional connection terminals allowing a valve circuit to be interrupted by an external switch.

Approvals and Conformities

• Explosion protection: ATEX (II 3G Ex ec IIC Gc / II 3D Ex tc IIIC Dc) and IECEx (Ex ec IIC Gc / Ex tc IIIC Dc). Suitable for zone 2/22.
• North America: UL Listed for the USA and Canada (UL 61010-1). Optional UL Recognized for Hazardous Locations (Class I, Zone 2; Class II, Zone 22; Class I, Div 2).
• Others: China Compulsory Certification (CCC) for hazardous applications in China.

Product Installation

Hot Swap Function

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. The use of the Hot Swap function is prohibited in the presence of an explosive atmosphere unless it can be proven by suitable test equipment that no explosive atmosphere is present for a certain period.

Product Connections

• Power supply for communication and displays: 5-pin spring-loaded terminal (24 V DC, CAN_H, SHIELDING, CAN_L, GND).
• Power supply for pneumatic valves: 2-pin spring-loaded terminal (AUX 24 V, GND).
• Fieldbus interface: CANopen/büS requires 2 terminating resistors (approx. 60 Ω between CAN_H and CAN_L when power is off). Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) uses RJ45 interfaces.
