BURKERT 20077187 (Type 8652) AirLINE valve island has been especially developed for process automation requirements. This specific configuration features 20 valve ports equipped with 2x 3/2-way WWC valves, a PROFIBUS DPV1 communication interface, and a stainless steel AirLINE Quick adapter plate. New diagnostic functions can be visualised on the LC display, both in clear text as well as symbols. This makes it easy to relate to the shown messages and helps to save time during start-up and maintenance. Furthermore, the diagnostic message is also available at the controller, enabling a fast overview of the plant status.

The hardware is optimised for installation at the bottom of the control cabinet, though installation on a standard rail is also possible. Key pneumatic functions ensure increased process reliability, such as integrated check valves in the exhaust air ducts that prevent unplanned actuation due to pressure peaks.

Key Features

• Safety-related shut-off: Valves can be safely shut off (SIA variant).
• High Availability: Supported by PROFINET S2 (system redundancy) on compatible modules.
• Process Reliability: Integrated pneumatic functions including check valves.
• Optimised Installation: Designed for the bottom of the control cabinet via AirLINE Quick.
• Explosion Protection: EX-variants available for ATEX / IECEx Zone 2, CCC, cURus HazLoc CL I, II, III Div 2.

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.

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.

Dimensions (16-, 20- and 24-fold)

Dimensions in mm. The 20-fold variant with intermediate supply has dimensions A=134, B=268, D=158.3, m=11, m'=7, n=5.

Product Installation and Assembly

To use the Hot Swap function, always observe a minimum distance to the front edge of the control cabinet when installing the valve island inside the control cabinet.

Electronic Module with Digital Inputs

The digital inputs are supplied (24 V) by the electronic module. Current is limited to maximum 30 mA per digital input. Standard 3-wire sensors and 2-wire sensors with voltages between 10…30 V as well as mechanical limit switches can be used. This model features 40 digital inputs.

Example Configuration

The following illustration shows a network with the example of AirLINE Type 8652 with Industrial Ethernet variant as master valve terminal and various AirLINE Type 8652 with büS variant as slave valve terminals.

Supplementary Instructions for EX Areas

DANGER

Danger from voltage:

• Before working on the device or system, switch off the power supply. Secure against reactivation.
• In an existing explosive atmosphere, the connection terminals for 24 V supply, SIA, EVS, and digital inputs may only be plugged in or unplugged when the power is switched off.
• The use of the Hot Swap function is prohibited in an existing explosive atmosphere.

WARNING

Danger of explosion due to electrostatic charge:

• Take appropriate measures to ensure that no electrostatic charge can build up in the potentially explosive area.
• Only clean the device surface by wiping it gently with a damp or antistatic cloth.

For explosion protection type "ec", install the device in an enclosure that meets the applicable requirements for explosion protection type "ec" according to EN/IEC 60079-0 and EN/IEC 60079-7 and has a degree of protection of at least IP54. For type "tc" (dust), the enclosure must have a degree of protection of at least IP6X.
