BURKERT 8652 AirLINE is a 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, and key pneumatic functions ensure increased process reliability.

Key features include:

• Safety-related shut-off of valves possible
• Higher plant availability with PROFINET S2 (system redundancy)
• Process reliability through pneumatic functions
• Optimised for installation at the bottom of the control cabinet
• EX-variants: ATEX / IECEx Zone 2, CCC, cURus HazLoc CL I, II, III Div 2

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 circuit functions including:

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

Approvals and Conformities

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

Dimensions

Product Connections

The valve island supports various communication interfaces including PROFIBUS DP, Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic), PROFINET S2, CANopen, and büS.

WARNING

CANopen requires 2 terminating resistors: one at the beginning of the network and one at the end. An indicator of the correct bus scheduling is the resistance between CAN_H and CAN_L when the power is switched off. This should be approx. 60 Ω.

Product Installation

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.

Safety-Related Shut-Off (SIA Variant)

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).
