ATTENTION! Risk of destruction!
Do not connect the power supply lines (+24 V DC) to the data lines (Data + -> Pin 4, Data - -> Pin 5).
Also the reverse connection of the power supply lines can lead to the destruction of the module.
Important note!
With long cable lengths an additional power supply feed is recommended, see following chapter.
5.2.
Intermediate power supply feed on LioN-Link I/O-modules
During the planning of a machine or a plant it has to be considered that starting from certain cable lengths an intermediate
power supply feed for the electronics and sensors of the I/O-modules can be necessary.
If the power supply for the I/O-modules is not sufficient they deliver a diagnostics message.
The warning threshold for the diagnostics is approximately 19 V.
5.2.1.
T-connector for intermediate power supply
An easy possibility of realizing the intermediate power supply on an I/O-module is the use of the T-connector 0906 UTP 104. Its
internal wiring is shown in the following drawing. The T-connector is screwed onto the link input (M12-plug) of a LioN-Link
I/O-module.
