BURKERT 20043311 (Type 8652 AirLINE) is an 8-slot electropneumatic valve island pre-configured for process automation environments. The unit features six 5/2-way bistable impulse solenoid valves (Circuit Function Z) on positions 1 through 6, and two blind plates on positions 7 and 8. It incorporates an anodised aluminium AirLINE Quick adapter plate designed for mounting directly to the control cabinet base or cabinet wall, venting exhaust air and guiding pneumatic connections directly through the cabinet floor.

Fieldbus communication is driven by an integrated Industrial Ethernet interface supporting multi-protocol operations, including PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic over two RJ45 ports (X1 and X2). Local diagnostics are displayed in plain text and symbols on the integrated LC display, and status words are forwarded cyclically to the higher-level PLC. The device operates on 24 V DC and handles operating pressures from vacuum (-1.00 bar) up to 10.00 bar using external auxiliary pilot air (3 to 10 bar).

AirLINE Quick Cabinet Floor Mounting

AirLINE Quick eliminates bulkheads and internal distribution piping inside the control cabinet. The adapter plate mechanically seals directly to a cutout in the cabinet floor or side wall, routing all working lines (Port 2 and 4) and exhaust lines (Port 3 and 5) directly outward.

AirLINE Quick Properties

Adapter Plate Material	Anodised aluminium (optional: Stainless steel 1.4301)
Push-in Fittings Material	Nickel-plated brass (optional: Stainless steel 1.4401)
Pneumatic Supply / Exhaust Ports	Push-in connector D10 mm, 3/8"
Pneumatic Working Ports	Push-in connector D6 mm, 1/4"
Permissible Mounting Locations	Control cabinet floor or control cabinet wall

Installation Clearance and Cabinet Access

When installing the valve island inside the control cabinet, maintain sufficient clearance between the valve island front edge and the cabinet door/frame. This spacing ensures accessible manual overrides and enables hot-swap removal of individual valve modules without dismounting adjacent units.

Fieldbus Gateway Module Type ME43

ME43 gateway modules integrated into Type 8652 are unconfigured ex works. Network parameter files (EDS, GSDML, or ESI) must be configured and assigned using Bürkert Communicator software Type 8920 prior to commissioning on the plant network.

Safety Functions and Explosion Protection

Type 8652 supports safety shutdown architectures through optional SIA (Safety-related Interruption Architecture) modules and EVS (External Valve Shutdown) circuits, interrupting pilot coil power independently of fieldbus communication via potential-free mechanical contacts.

Hazardous Area Special Conditions

For installation in hazardous areas classified Zone 2/22 or Class I/II/III Division 2:

• Install the unit in an enclosure certified to EN/IEC 60079-0 and EN/IEC 60079-7 with minimum IP54 protection for gas (Category 3G, Ex ec) or IP6X for dust (Category 3D, Ex tc).
• Supply transient protection set not to exceed 140% of the nominal peak voltage.
• Do not connect or disconnect electrical spring terminals (24 V power, SIA, EVS, digital inputs) while energized in the presence of an explosive atmosphere.
• Hot Swap removal or insertion of valve slices is strictly prohibited in an active explosive atmosphere unless the area is proven non-hazardous by certified testing equipment.
