Burkert Type 8652 AirLINE valve island has been especially developed for process automation requirements. Diagnostic functions can be 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

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.

• 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 of the control cabinet.

Circuit Functions

The Type 8652 supports multiple circuit functions, including standard and SIA (safety-related shut-off) variants:

• 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. Pressure applied via port (1).
• 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.

Approvals and Conformities

• Explosion protection: Optional ATEX/IECEx suitable for 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.

Explosion Protection Safety

In explosive atmospheres, the Hot Swap function is prohibited. Connection terminals for 24 V power, SIA, EVS, and digital inputs must only be connected or disconnected when the power is switched off, unless the absence of an explosive atmosphere is proven.

Product Connections

Power Supply

• Communication and displays: 5-pin spring-loaded terminal (24 V DC, CAN_H, Shielding, CAN_L, GND).
• Pneumatic valves: 2-pin spring-loaded terminal (AUX 24 V, GND). The interface plate has a dedicated terminal to which the pneumatic valves' power supply is connected.

Fieldbus Interface

Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, CC-Link IE Field Basic) or PROFINET S2 uses Interface X1 and X2 RJ45.

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.

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 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. The module provides open-circuit detection with 2-wire sensors and short-circuit detection with 3-wire sensors.

Valves Type 6534 for 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).

Module-Based Safety Shutdown (Optional)

Connections for module-based safety shutdown use a pluggable 12-pin spring-loaded terminal. Terminal 1 corresponds to valve unit 1, Terminal 2 to valve unit 2, etc. The required switching capacity of the contact is 1.5 A / 24 V DC.

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant as the master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.
