SystemDescription
The Type 8644 Bürkert AirLINE is an electrical and pneumatic automation system which was developed for use in
the control cabinet or switch box. In a continuous system all electronic and pneumatic components are standardized,
enabling pneumatic, electric and electronic modules with various functions to be combined very easily with each
other by the observation of simple rules. All components are connected by a locking mechanism. At the same time
the required electrical connections are also established. For example, valves and power outputs can be combined
with one field bus connection only. A large number of electrical modules (terminals) can be combined very easily
with the valves mounted on special pneumatic modules (valve discs).
In its minimum configuration the system consists of the interface module IM151, a power module and the valve block.
Electronic modules of the ET200S system can be installed before and after the valve block. A power module must
always be provided after the interface module and without fail before the valve block. If the configuration requires
electronic modules after the valve block, a power module must be placed without fail after the valve block or before
the electronic modules, as the power supply voltage must be fed again. The maximum configuration of the decen-
tralized peripheral device comprises 64 nodes (including interface module, power modules, peripheral modules and
pneumatic base modules).
In its maximum configuration the valve block comprises 64x 11 mm (ME02) add-on dimension valves and 32x 16.5 mm
(ME03) add-on dimension valves which function monostably. If the configuration of the valve block also provides for
valves of Type 0461, a maximum of 24x 16.5 mm add-on dimension valves is authorized.
The ET200S supports the removal and insertion of modules during operation (RUN operating state). The function
module can be removed during operation the same as the electronic modules of the ET200S. However, the oper-
ating pressure must be switched off beforehand! To do this, it is essential to observe Chapter “7. Structure and
function of the modules”.
