BURKERT 309093 (Type 8652) is a 12-slot AirLINE valve island configured with an AirLINE Quick anodised aluminium adapter plate and a 5-pin büS/CANopen communication interface. Developed for process automation, the assembly integrates twelve 11 mm solenoid valve positions consisting of six dual 3/2-way normally closed valves (Circuit Function C) and six 5/2-way monostable valves (Circuit Function H), delivering individual nominal flow rates up to 310 l/min.

The hardware design is optimized for direct installation onto the control cabinet floor or wall using the AirLINE Quick adapter, eliminating intermediate bulkhead fittings and significantly reducing cabinet volume requirements. Process safety features include external auxiliary pilot air supply operating between 3 and 10 bar, working pressure capabilities from vacuum down to -1.00 bar up to 10.00 bar, and integrated diagnostics reported on the local LC display as well as cyclically to the supervisory fieldbus controller.

Circuit Functions

The Type 8652 platform supports standardized pilot pneumatic circuit functions based on Type 6534 solenoid valves. Article 309093 implements Circuit Functions C and H as primary control elements:

• Circuit Function C (CF C): Dual 3/2-way solenoid valve, servo-assisted, normally closed in de-energised state. Each station controls two independent single-acting actuators. Nominal flow rate QNn is 270 l/min air.
• Circuit Function H (CF H): 5/2-way solenoid valve, servo-assisted, monostable with spring return. Pressure applied at port 1 directs air to port 2 or 4, controlling double-acting actuators. Nominal flow rate QNn is 290 l/min air.
• Circuit Function D (CF D): Dual 3/2-way solenoid valve, servo-assisted, normally open. Nominal flow rate QNn is 310 l/min air.
• Circuit Function L (CF L): 5/3-way solenoid valve, servo-assisted, middle position closed (all ports locked). Nominal flow rate QNn is 275 l/min air.
• Circuit Function M (CF M): 5/3-way solenoid valve, servo-assisted, middle position pressurized (ports 2 and 4 ventilated). Nominal flow rate QNn is 300 l/min air.
• Circuit Function N (CF N): 5/3-way solenoid valve, servo-assisted, middle position exhausted (ports 2 and 4 exhausted). Nominal flow rate QNn is 300 l/min air.
• Circuit Function Z (CF Z): 5/2-way solenoid valve, bistable impulse variant with 2 solenoid coils. Nominal flow rate QNn is 290 l/min air.

All standard valves include manual overrides with latching and spring-return operation.

AirLINE Quick Adapter Plate

AirLINE Quick allows direct flush mounting of the valve terminal onto the control cabinet floor or wall, penetrating the enclosure boundary with sealed pneumatic connections.

AirLINE Quick Features

• Reduces internal cabinet space consumption by eliminating internal pneumatic distribution tubing.
• Direct hose connections at the cabinet floor reduce installation hours and field routing errors.
• Adapter plate manufactured from anodised aluminium (article 309093) or optional stainless steel 1.4301.
• Pneumatic connections fitted with nickel-plated brass push-in fittings: D10 mm for supply/exhaust and D6 mm for working ports.

Dimensions and Installation Geometry

Dimensions for 4-, 8-, and 12-slot configurations without intermediate supply:

Variant	Dimension A (mm)	Dimension B (mm)	Mounting C	m (Stations)	n (Base Elements)
4-fold	66	—	4 x M5	3	1
8-fold	35	111	8 x M5	7	2
12-fold (Article 309093)	77	154	10 x M5	11	3

For 16-, 20-, and 24-slot platforms, the terminal expands modularly with optional intermediate supply blocks (dimension D = 114.3 mm or 158.3 mm) and up to 10 x M5 mounting points.

Mounting is supported either directly on a standard DIN rail conforming to EN 50022 (35 x 7.5 mm or 35 x 15 mm) or via the AirLINE Quick cutout on the control cabinet base.

Electrical and Bus Connections

Article 309093 operates with dedicated galvanic separation between fieldbus communication electronics and pneumatic solenoid power circuits.

büS / CANopen 5-Pin Spring Terminal Strip

The 5-pin spring terminal provides power to the internal communications processor, display unit, and CAN-based büS line:

Pin Position	Terminal Marking	Core Colour	Signal Assignment
Pin 1	+24 V DC	Red	Logic power supply (+24 V DC)
Pin 2	CAN_H	White	büS / CAN_H signal line
Pin 3	SHIELD	Green	Cable shield connection
Pin 4	CAN_L	Blue	büS / CAN_L signal line
Pin 5	GND	Black	Logic ground (0 V DC)

Maximum supported conductor cross-section is ≤ 1.5 mm².

CANopen Bus Termination Requirement

CANopen and büS network segments require a 120 Ω terminating resistor at each end of the bus line. When the system is de-energised, the measured resistance between CAN_H and CAN_L across the network must be approximately 60 Ω.

Pneumatic Valve Power Supply (2-Pin Spring Terminal)

The interface plate incorporates an independent 2-pin spring-loaded terminal strip to power the 24 V DC pneumatic coils:

Terminal	Wire Colour	Assignment
Clip 1	Red	AUX +24 V DC (valve coil supply)
Clip 2	Black	GND (0 V DC valve return)

Control Cabinet Installation Guidelines

When positioning the valve island inside the control cabinet, clearance dimensions must be preserved to permit replacement of individual valve slices and access to manual overrides without removing the island.

AirLINE Quick Control Cabinet Installation

Maintain the manufacturer minimum clearance distances between the valve terminal and the cabinet door/front edge. Adhering to these clearances ensures that pneumatic modules and electronic sub-assemblies can be serviced without unbolting the baseplate.

Software Configuration and Network Topology

Article 309093 communicates over the CANopen-based büS platform within Bürkert's Efficient Device Integration Platform (EDIP). A Type 8652 equipped with Industrial Ethernet (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, or CC-Link IE Field Basic) can function as a fieldbus master, controlling downstream büS slave valve islands in a coordinated subsystem.

Commissioning, diagnostics, and firmware maintenance are carried out via the Bürkert Communicator software (Type 8920). Connecting a PC to the büS port requires the USB büS interface set (article no. 772426 or 772551). The software provides:

• Graphical parameter setting and live diagnosis of all valve slots.
• Mapping of cyclic process values and acyclic status words.
• Backup and restoration of island device configuration files.
• Firmware upgrades across all connected EDIP sub-modules.

Hazardous Area Approvals and Operating Conditions

When ordered with applicable explosion protection configurations, Type 8652 valve islands comply with international standards for Zone 2/22 and Division 2 environments:

Hazardous Location Electrical and Hot Swap Restrictions

For Zone 2 / Zone 22 installations, the valve terminal must be installed inside an enclosure providing a minimum ingress protection of IP54 (for Category 3G gas atmospheres) or IP6X (for Category 3D dust atmospheres). Transient overvoltage protection must prevent voltage spikes exceeding 140% of the nominal peak supply. Terminals and push-in plugs must not be connected or disconnected while energised in the presence of an explosive atmosphere.
