Product description
Type 8650 REV.2
6 PRODUCT DESCRIPTION
Valve block AirLINE Ex Type 8650 (hereafter also AirLINE Ex) is a modular, electric and pneumatic auto-
mation system with degree of protection IP30. The device is intended for use with the decentral I/O system
SIMATIC ET 200iSP from Siemens and is designed for use in potentially explosive environments.
AirLINE Ex was developed in close cooperation with Siemens. In combination with ET 200iSP modules, this
results in a continuous system of electronic and pneumatic components. With adherence to simple rules,
pneumatic, electric and electronic modules of various functionalities can be combined with each other to
suit the specic application.
The AirLINE Ex system modules function as digital outputs with integrated valves.
The components are connected to each other via screws or locks. Both the electric and pneumatic connec-
tions are formed in this manner.
Due to the assemblies’ design as linearly arranged “segments” (“valve segments”, “connection segments”),
future expansions or revisions of the AirLINE Ex are possible (e.g. for an expansion of the system actuated
by AirLINE Ex).
The integration in ET 200iSP is practically seamless, including with regard to the projection in SIMATIC
STEP 7 and PCS7.
The pilot valves integrated in AirLINE Ex allow the actuation of pneumatic actuators in the eld, such as
process valves or pneumatic cylinders.
The Revision 2 (REV.2) of Type 8650 AirLINE Ex is primarily depicted in this document. See chapter “6.3
Information on revision status and compatibility” on page 17 for the dierences between REV.1 and
REV.2.
The connection segments of AirLINE Ex REV.2 can optionally be equipped with a pressure switch or
pressure sensor. This simplies the automated monitoring of the supply pressure.
An on/o valve can be attached to AirLINE Ex REV.2 connection segments as well.
AirLINE Ex can also be used in this manner for other applications in which safety requirements must be
ensured (see chapter “14 On/o valve” on page 54).

Product description
Type 8650 REV.2
The electronic modules, pneumatic base modules and connection modules, as well as the single valves of
Types 6524, 6525, 6526 and 6527, were revised for Type 8650 REV.2 to implement various optimisations.
The interfaces (mechanical, electric, software) of the electronic modules and terminal modules were
unchanged.
6.3.3
Compatibility must be ensured in the following instances:
• Replacement of single valves with 11 mm width per valve (see chapter “16.13 replace valve” on
page 80).
• Expansion, repair or renovation of valve blocks (see chapter “16.9 Assembling, renovating and
expanding a device (valve block) with individual segments”)
• The pneumatic modules (base modules and connection modules) of REV.1 and REV.2 are not
compatible with each other.
Dierences remain in
• the electrical data (electronic modules of REV.2 have slightly more output)
• the Ex approvals
• the permissible ambient temperature range during operation (expanded to 60 °C for REV.2)
• the external dimensions
• the housing colour of the terminal and electronic modules
• Omission of blue cover aps in REV.2
In the projection there is no dierence between REV.1 and REV.2 devices.
Revision 2 (REV.2) is mainly described and presented in this document.
The documentation of Revision 1 (REV.1) is still available at: country.burkert.com

is compliant with degree of protection IP30.
DANGER
The terminal modules (with standing system wiring) are listed in the Ex degree of protection “Ex e”
(increased safety).
▶You must disable the system’s operating voltage before working on the terminal modules.
Additional information can be found in the SIMATIC ET 200iSP handbook.
For systems in the potentially explosive atmosphere, which are installed in a control cabinet, ensure the
following:
• The control cabinet must be approved for use in the potentially explosive atmosphere.
• The control cabinet must be dimensioned in such a way that the resulting heat loss can be discharged
to the outside using suitable means.
• The internal temperature of the control cabinet must not exceed the maximum permitted ambient tem-
perature for the device.
