BURKERT 20111639 (Type 8652) is an 8-slot AirLINE valve island featuring Industrial Ethernet communication, stainless steel AirLINE Quick interface, integrated check valves, and pneumatic HotSwap functionality.

BURKERT 20111639 (Type 8652) is an 8-slot AirLINE pneumatic valve island configured for process automation inside control cabinets. Built with a stainless steel AirLINE Quick baseplate adapter, this variant mounts directly through the cabinet floor or wall cutout, placing external pneumatic push-in fittings outside the enclosure while maintaining IP65 and NEMA Type 4X protection in closed cabinets. Fieldbus integration is handled via Industrial Ethernet supporting PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic through two MDI/MDI-X RJ45 sockets. The unit is factory-assembled with three active valve slices: position 1 and position 2 host 5/2-way monostable pilot valves (Circuit Function H), position 3 hosts a double 3/2-way normally closed valve (Circuit Function C), and positions 4 through 8 are sealed with blanking plates for clean system expansion.

Process reliability features include integrated check valves installed in exhaust ducts 3 (R) and 5 (S) to eliminate unwanted valve actuation from exhaust backpressure spikes. The pneumatic supply rail incorporates integrated HotSwap check functionality on port 1 (P), allowing individual Type 6534 pilot valves to be replaced during live operations without venting system air pressure. An integrated LC display visualizes operating statuses, valve switching cycle counters, and diagnostic messages in plain text and symbols.

Dimensions are given in millimeters. Mounting pitch and fastening coordinates for 4-, 8-, and 12-slot baseplate configurations follow standard spacing:
| Variant | A (mm) | B (mm) | Fastening Screws C | m | n |
|---|---|---|---|---|---|
| 4-fold | 66 | — | 4 x M5 | 3 | 1 |
| 8-fold (SKU 20111639) | 35 | 111 | 8 x M5 | 7 | 2 |
| 12-fold | 77 | 154 | 10 x M5 | 11 | 3 |
Each valve slice features a standard 11 mm width, maintaining a compact footprint regardless of pilot valve selection.
The 8652 terminal separates logic and communication electronics from the pneumatic valve coil power supply through independent push-in spring-loaded terminals.
| Terminal Type | Pin / Contact | Color Code | Signal Assignment |
|---|---|---|---|
| 5-Pin Spring Terminal (Logic/Display) | Pin 1 | Red | +24 V DC (Logic power) |
| Pin 2 | White | CAN_H (internal büS connection) | |
| Pin 3 | Green | Shielding | |
| Pin 4 | Blue | CAN_L (internal büS connection) | |
| Pin 5 | Black | GND (0 V DC) | |

Isolated Power Supplies
The pneumatic valve coils and communication logic modules must be powered from separated circuits. Cable cross-sections up to 1.5 mm² are supported by the spring-loaded terminal blocks.

Industrial Ethernet interfaces X1 and X2 provide 100BASE-TX communication with integrated dual-port switching capability for line topologies:
| Pin | RJ45 Signal Assignment |
|---|---|
| 1 | TX+ (Transmit Data +) |
| 2 | TX- (Transmit Data -) |
| 3 | RX+ (Receive Data +) |
| 4 | Not connected (N.C.) |
| 5 | Not connected (N.C.) |
| 6 | RX- (Receive Data -) |
| 7 | Not connected (N.C.) |
| 8 | Not connected (N.C.) |
To ensure proper tool clearance and manual access when replacing valve slices under live pressure, maintain minimum spatial clearances to the cabinet door and walls.

Installation Clearance for HotSwap
Maintain adequate clear space between the front edge of the 8652 valve terminal and the control cabinet door. Obstructing the front clearance impedes valve extraction and prevents replacement of modules without disrupting neighboring operational stations.
SKU 20111639 uses the standard 24 V interface plate configuration without modular safety-related shut-off (SIA). The main assembly comprises the base pneumatic manifold, electronic backplane bus, fieldbus communication head, and 11 mm valve stations.

The integrated Industrial Ethernet head enables the valve island to operate as an automation master or node, connecting downstream büS/CANopen valve islands or sensor modules.

Commissioning, parameter configuration, cycle counting, and diagnostic polling are carried out via the Bürkert Communicator software (Type 8920) across büS or Ethernet interfaces.
Individual valve positions can be serviced or reconfigured using Type 6534 pilot valves (11 mm station width, 4 mm nominal orifice, 24 V DC):
