The BURKERT Type 8647 AirLINE SP is a modular, electropneumatic automation system consisting of connection and valve modules. It has been especially developed for safe and complete integration into the decentralised peripheral system "SIMATIC ET 200SP" and "SIMATIC ET 200SP HA" from Siemens. Pneumatically operated process valves, pneumatic cylinders, or other pneumatic components can be connected to the pneumatic outputs. If the pneumatic components are installed with position feedbacks, the position of the actuated pneumatic components can be displayed on the associated pilot valve via the LC display.

System Integration

The valve block is used to incorporate pneumatic pilot valves directly in SIMATIC ET 200SP/SP HA and to activate them via the Siemens system. Parameterization and configuration take place using the same tools as for SIMATIC ET 200SP/SP HA, such as SIMATIC "STEP 7", "TIA Portal", or "PCS7". Integration in various PROFIBUS systems or PROFINET systems occurs via GSD/GSDML.

Solenoid Pilot Valves

The valve block supports multiple pilot valve types to suit different circuit functions and flow requirements.

Type 6524 and Type 6525

The pilot valve Type 6524 (single and double valve) and Type 6525 (single valve) consist of a pilot flipper solenoid valve Type 6144 and a pneumatic seat valve. The circuit function allows switching of high pressures with low power consumption and short switching times. The pilot valves are equipped with a manual override as standard.

• Circuit functions: 3/2-way, 2x 3/2-way (Type 6524), and 5/2-way (Type 6525).
• Flow rate: 300 l/min.
• Nominal power: 0.8 W per valve.

Type 0460

The solenoid valve Type 0460 consists of a pneumatic valve body fitted with a double coil pilot valve. The active principle enables the switching of higher pressures at lower power consumption and short switching times. All valves are equipped with manual override as a standard.

• Circuit functions: 5/2-way impulse and 5/3-way bistable.
• Flow rate: 200 l/min.
• Nominal power: 0.5 W to 1 W depending on function.

AirLINE Quick Adapter

AirLINE Quick considerably reduces the use of components in the control cabinet. With the AirLINE Quick Adapter, the valve terminal is adapted directly to the control cabinet floor or control cabinet wall. This reduces the space requirement in the control cabinet and minimizes installation effort due to hose connections directly at the bottom of the control cabinet.

• Material: Stainless steel 1.4301 or anodised aluminium.
• Valve slots: 4, 8, 12, 16, 24.
• Pneumatic Supply / Exhaust: G 1/4", Push-in D 3/8".

Safety-Related Shut-Off

The valve block supports safety-related applications through different shut-off variants:

• SIA or EVS shut-off function: Allows an external shutdown of individual valves or a module-by-module shutdown of all valves. The diagnostic functions and the displays remain available on the LC display of the PQ modules.
• System setup with the F-PM-E power module: If operated in the potential group of an F-PM-E 24VDC/8A PPM ST power module of the ET 200SP, the load voltage of the valve block can be shut down by the power module for safety reasons. Valves of Types 6524 and 6525 return to their rest position. This variant meets the requirements for safety-related control systems in accordance with applicable standards (e.g., DIN EN ISO 13849 or EN IEC 62061).

Safety Application Limits

The electrical shutdown of valve Types 6524 and 6525 causes them to return to the rest position. Using manual override to operate valves overrides the electrical shutdown. For safety applications, either use valve variants without manual override or protect the manual override against unintentional adjustment.

Approvals and Conformities

• Explosion Protection: Optional category 3 device suitable for zone 2 (ATEX: BVS 18 ATEX E 078 XII 3G Ex ec IIC T4 Gc / IECEx: IEC Ex BVS 18.0068 X Ex ec IIC T4 Gc).
• North America: Optional UL Listed for the USA and Canada according to UL 61010-1 and CAN/CSA-C22.2 No. 61010-1.

Revision Information (REV.1 vs REV.2)

The single valves of Types 6524 and 6525, the pneumatic base modules, the connection units, and the control cabinet base adaptation AirLINE Quick have been revised (REV.2). Compared to REV.1, the flange patterns of the valves have been standardised towards the pneumatic base modules. The single valves 3/2-way and 5/2-way as well as the double valves 2x3/2-way now have the same unified pneumatic flange pattern (FM20). REV.1 and REV.2 single valves are not compatible and must be replaced with the corresponding revision.
