Operating instructions - SBU IO-Link
B02
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
further conditions of use are described in more detail in the chapter Usage conditions. The SBU IO-Link
may only be put into operation after the following documents have been read:
-
<Explanation of the EU directives>
-
These assembly/operating instructions
DANGER
Danger due to use of the SBU IO-Link other than for the intended purpose
People can be seriously injured if the SBU IO-Link is used improperly or for a purpose
other than that intended. Also, the SBU IO-Link may sustain damage.
Use the SBU IO-Link only for its intended purpose!
Do not modify the SBU IO-Link !
Do not exceed the operating voltage!
INFO
Be sure to observe all the information in these operating instructions, in
particular the safety information. It must be read and observed before all
activities on the SBU IO-Link .
Any use, adjustment and variation other than that described in these operating
instructions is considered to be improper and contrary to the intended purpose
of the SBU IO-Link !
