Burkert Type 8647 AirLINE SP is a modular, electropneumatic automation system consisting of connection and valve modules. It is 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.

Connection Units

The pneumatic supply and deaeration of the valve block occurs via connection units. 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.

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 or with eight valve slots.

Electronic Base Module (PQ module)

The electronic base module contains the electrical plug-in connections for the valves, the valve driving electronics, and the visual status indicators (LEDs for displaying the device status and a graphics LCD).

Pneumatic Base Module

The pneumatic base module supports the valves, ensures the pneumatic supply and deaeration of the valves, and provides the pneumatic outputs.

Solenoid Valves for Pneumatics

Type 6524 and Type 6525

Type 6524 is a 3/2-way valve or a 2x3/2-way valve. Type 6525 is a 5/2-way valve. The valves consist of a flipper solenoid valve as the pilot control and a pneumatic seat valve as the amplifier. They are monostable and equipped as standard with manual override.

Type 0460

The Type 0460 valve consists of two pilot solenoid valves and one pneumatic slide valve. The active principle enables the switching of higher pressures at lower power consumption and short switching times. 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.

Advantages

• Reduced space requirement in the control cabinet
• Makes it possible to use more compact control cabinets
• Reduced installation effort due to hose connections directly at the bottom of the control cabinet

Approvals and Conformities

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

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.
