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 systems "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.

System Overview

Combining modules from the distributed Siemens I/O systems SIMATIC ET 200SP/SP HA with the valve block AirLINE SP Type 8647 provides an integrated system of electronic and pneumatic components. Depending on the requirement, electrical and pneumatic modules with various functions can be combined with each other.

Connection Units

The pneumatic supply and deaeration of the valve block occurs via connection units. Furthermore, the valve block is fixed to the standard rail via the connection units. Connection units can be optionally equipped with a pressure gauge or electronic pressure sensor. At the variant with electronic pressure sensor, the measured supply pressure is provided as an analog value via ET 200SP.

Valve Units

Valve units convert the electrical control signals of the interface module into pneumatic output signals and provide the pneumatic outputs. There are valve units with four valve slots (4-slot valve unit) or with eight valve slots (8-slot valve unit).

Solenoid Valves

• 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.
• Type 0460: The solenoid valve Type 0460 consists of a pneumatic valve body fitted with a double coil pilot valve. The valves offer the functions 5/2-way pulse as well as 5/3-way and are equipped with manual override as standard.

AirLINE Quick

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. The AirLINE Quick Adapter Plate is available in stainless steel 1.4301 or anodised aluminium.

Application Planning

Valve block AirLINE SP Type 8647 is intended for use in automation systems within buildings. It must be installed in a suitable control cabinet or in a suitable housing. In this case, suitable means with a degree of protection of at least IP54 in accordance with EN 60529. The ambient conditions for operating the devices must be observed.

Safety-related shut-off

The electrical shutdown of valve Types 6524 and 6525 causes them to return to the rest position. The selection of the appropriate circuit function of the valve (CFC, CFD or CFH) depends on the application and is the responsibility of the user. To avoid brief back pressures in the event of a safety shutdown, the use of valve blocks with integrated check valves is strongly recommended.
