BURKERT 20081087 Type 8652 AirLINE is a 16-slot electro-pneumatic valve island engineered for process automation environments, pre-configured with 13 dual 3/2-way normally closed valves (CF-C) and 3 blind plates on an AirLINE Quick anodised aluminium base. The system integrates an ME43 fieldbus gateway supporting Industrial Ethernet protocols (PROFINET IO, EtherNet/IP, Modbus TCP, EtherCAT, and CC-Link IE Field Basic) via dual RJ45 ports. Operating from a 24 V DC supply across a pressure range of -1 bar to 10 bar, the unit provides a nominal air flow rate of 310 l/min per valve station at 6 bar inlet pressure and 1 bar differential pressure.

Product Architecture and Modular Options

Article 20081087 is built with a standard 24 V interface plate without modular shut-off. Modular configurations within Type 8652 accommodate optional electronic sub-modules:

Digital Input Modules (8DI Module, Optional)

Type 8652 supports up to 48 digital inputs across modular stations. Each input is supplied with 24 V DC, current-limited to 30 mA, accepting 2-wire, 3-wire, or dry contact mechanical switches.

Property	Value
Diagnostics	Open-circuit detection (2-wire sensors), short-circuit detection (3-wire sensors)
Switching Threshold	V_OFF = 0 to 5 V; V_ON = 10 to 30 V
Input Current at V_ON	Max. 5.7 mA per channel (typical at 24 V DC)
Input Impedance	> 4 kΩ
Galvanic Isolation	No, common reference potential for all channels
Maximum Cable Length	< 30 m (cross-section ≤ 1.5 mm²)

Safety-Related Shutdown (SIA Variants, Optional)

For functional safety architectures, Type 6534 SIA replacement valves integrate dedicated terminal blocks to cut coil power independently of fieldbus commands via external potential-free contacts. Alternatively, a 12-pin spring-loaded terminal module provides group-based emergency shut-off with contact switching ratings up to 1.5 A at 24 V DC.

Network Topology Architecture

An AirLINE Type 8652 valve island equipped with an Industrial Ethernet interface functions as an intelligent master valve terminal. Downstream sub-networks of Type 8652 islands fitted with büS interfaces connect as slave terminals via CANopen-based büS links, consolidating fieldbus nodes into a single Ethernet IP address.

Commissioning with Bürkert Communicator Software

Configuration and diagnostics are carried out through the Bürkert Communicator software (Type 8920), which operates on the EDIP (Efficient Device Integration Platform) framework.

• Complete monitoring of cyclic process values and acyclic diagnostic data
• Address mapping between fieldbus gateways and sub-network bus devices
• Graphical configuration interface for sub-system control logic
• Firmware upgrades, backup, and restore routines for connected EDIP hardware
