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.
