Use for the intended purpose
The SBU IO-Link serves to acquire the signals for the 0°/90° or closed/open position detection of a valve. The SBU
IO-Link is mounted on a pneumatic quarter turn actuator with a VDE/VDI 3845 AA2 interface. Quarter turn actuators
not having these interfaces require an additional attachment kit for adaptation. The SBU IO-Link can also optional be
used as a detached unit with linear actuators.
The additional interface for two 24 V DC proximity switches allows the two end position sensors of the linear actuator
to be electrically connected there and their signals processed by the microprocessor-assisted SBU IO-Link. Further
input signals and output signals that are available are described in the following chapters. The SBU IO-Link is
suitable only for the non-explosive zone and may be operated only with a 24 V DC power supply. The SBU IO-Link is
used only in an area that is not potentially explosive.
The SBU IO-Link may only be put into operation after the following documents have been read:
-
<Explanation of the EU directives>
-
Original assembly instructions
Failure to observe this <intended purpose of use> represents gross negligence and relieves the manufacturer
EBRO-Armaturen of its product liability.

Marking of the SBU IO-Link
Each SBU IO-Link is marked with the following data on the housing or on the type plate:
Example of an SBU IO-Link standard version
(outside of a potentially explosive zone)
The type plate describes the temperature range, electrical data, EBRO article no. and IP protection class applying to
the SBU IO-Link . In addition, the date of manufacture and the CE mark are also printed on it. So that the installed
SBU IO-Link remains identifiable, it should not be covered.
