Burkert 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, 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 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 3/2-way, 5/2-way, and 5/3-way solenoid valves (Circuit functions C, D, H, L, M, N, Z).

SIA Variant (for safety-related shut-off)

Type 6534 valves are available in an SIA variant 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).

Approvals and Conformities

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

EX Zone Safety Notes

When using the device in potentially explosive atmospheres, the Hot Swap function is prohibited unless it can be proven by suitable test equipment that no explosive atmosphere is present during the operation. Terminals for 24 V supply, SIA, EVS, and digital inputs must only be connected or disconnected in a de-energized state.

Dimensions

Variant 4-, 8- and 12-fold

Variant 16-, 20- and 24-fold

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: Supports Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic), PROFINET S2, PROFIBUS DP, CANopen, and büS.

CANopen Terminating Resistors

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.

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. Maximum cable length is < 30 m.

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.

Ordering Information

The Type 8652 valve island is highly modular. Replacement valves (Type 6534) and SIA variants can be ordered as spare parts. The Bürkert Communicator software (Type 8920) is recommended for configuration, parametrisation, and diagnosis of EDIP devices.
