BURKERT 20135392 Type 8652 AirLINE is a preconfigured 12-slot pneumatic valve island developed specifically for process automation installations. Equipped with an integrated ME43 Industrial Ethernet communication interface supporting PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic over dual RJ45 ports, the terminal provides direct process control and comprehensive diagnostics on an LC display as clear text and symbols. Diagnostics are also transmitted cyclically to the higher-level PLC to accelerate commissioning and fault tracking.

The 20135392 configuration is assembled on an AirLINE Quick anodised aluminium baseplate for direct mounting to the floor or wall of a control cabinet. It features brass push-in connectors (D10 supply port, D6 working ports), internal auxiliary pilot air supply, and an auxiliary left threaded feed (G 1/4" and M7). The valve bank includes 11 standard stations with 2x 3/2-way normally closed valves and a 12th station equipped with a Type 6534 SIA safety shut-off valve with potential-free shutdown contacts, controlling up to 24 independent pneumatic paths.

AirLINE Quick Adapter Plate

The AirLINE Quick system allows the valve terminal to mount directly onto the floor or wall of a control cabinet, leading pneumatic tubing straight through the enclosure cutout. This layout eliminates intermediate bulkheads and internal tubing runs, allowing significantly smaller cabinet enclosures.

Mounting Position	Control cabinet floor or cabinet wall

Dimensions and Cabinet Mounting

For a 12-slot valve terminal, external dimensions follow standardized Burkert pitch dimensions. Mounting is supported directly onto the cabinet wall, cabinet floor cutout, or standard DIN rails EN 50022 (35 x 7.5 mm or 35 x 15 mm).

Terminal Size	Dimension A (mm)	Dimension B (mm)	Mounting Screws C	Pitch Index m	Spacing Index n
4-fold	66	—	4 x M5	3	1
8-fold	35	111	8 x M5	7	2
12-fold (20135392)	77	154	10 x M5	11	3

Electrical and Fieldbus Connections

The valve terminal provides galvanic and electrical separation between the communication electronics and the pneumatic coil power circuits. Both power feeds must be supplied independently.

Communication and Display Power Supply

Power supply to the display and fieldbus communication module is wired through a 5-pin spring-loaded terminal block (wire cross-section ≤ 1.5 mm²):

Pin Position	Terminal Colour	Function / Assignment
1	Red	24 V DC
2	White	CAN_H (büS connection)
3	Green	Shielding
4	Blue	CAN_L (büS connection)
5	Black	0 V DC (GND)

Pneumatic Valve Power Supply

Pneumatic valve coils receive power via a dedicated 2-pin spring-loaded terminal on the interface plate:

Terminal Clip	Terminal Colour	Function / Assignment
1	Red	AUX 24 V DC
2	Black	0 V DC (GND)

Industrial Ethernet Interface (X1 and X2)

Dual RJ45 sockets support daisy-chain topology and ring redundancy protocols across Industrial Ethernet standards:

RJ45 Pin	Signal Assignment	Description
1	TX+	Transmit Data +
2	TX-	Transmit Data -
3	RX+	Receive Data +
4	N.C.	Not connected
5	N.C.	Not connected
6	RX-	Receive Data -
7	N.C.	Not connected
8	N.C.	Not connected

Cabinet Installation and HotSwap Clearance

Type 8652 includes pneumatic HotSwap in supply port 1 (P), allowing individual pilot valves to be replaced under full line pressure without shutting down adjacent actuators or bleeding the main air line. Check valves built into exhaust channels 3 (R) and 5 (S) prevent reverse pressure surges from inadvertently moving single-acting cylinders.

HotSwap Maintenance Distance

To safely insert and release individual valve slices using the HotSwap mechanism, adhere to the minimum spacing between the terminal body and the front edge or doors of the control cabinet as defined in the Type 8652 operating instructions.

Safety Shutdown (SIA) and Circuit Functions

Position 12 on model 20135392 is fitted with a Type 6534 SIA variant valve. While slots 1 to 11 use standard 2x 3/2-way normally closed valves with manual overrides, the SIA variant features dedicated electrical terminal connections to interrupt the coil circuit externally via emergency contacts or safety relays, completely bypassing bus communication.

Feature	SIA Safety Shutdown Specification
Terminal Type	Pluggable screw-type terminal, 2-pin, mechanically coded
Conductor Cross-Section	0.14 mm² to 1.5 mm² (AWG 28–16), rigid or flexible
Contact Switching Capacity	0.5 A at 24 V DC
Manual Override	None (manual operation omitted on SIA versions)
Delivery Condition	Fitted with removable bypass bridge for immediate commissioning
External Contact Type	Potential-free contact (mechanical safety switch or safety relay)

Network Topology Example

Type 8652 with Industrial Ethernet acts as a fieldbus master gateway that coordinates pneumatic sub-stations across an automation cell. Downstream Bürkert büS valve islands can be integrated into the network topology as slaves.

Configuration, parameterization, and diagnostic logging are executed using the Bürkert Communicator software (Type 8920) on the EDIP platform via a PC-linked USB-büS interface adapter.

Potentially Explosive Atmosphere Precautions

Terminal blocks for 24 V power, SIA shutdown, and digital inputs must only be connected or disconnected in an unpowered state when an explosive atmosphere is present. Pneumatic HotSwap must not be performed in hazardous locations unless the area is verified to be non-explosive using calibrated test equipment. For Zone 2 (3G) installations, the cabinet enclosure must provide at least IP54 ingress protection; for Zone 22 (3D), at least IP6X is required.
