WARNING
I/O port – Sensor supply:
The sensor supply may only be carried out via the specified power
connection (Power X03 --> U
S
+24V/GND_U
S
) of the module. An external
power supply over the I/O port (Port X1–X8 --> Pin1/Pin3) is not permitted
and can lead to a destruction of the module electronics!
WARNING
I/O port connection (IO-Link – Class B):
The sensor supply (Port X5–X8 --> Pin1/Pin3) and the extended sensor
supply (Port X5–X8 --> Pin2/Pin5) are galvanic isolated from each other. If
the reference potentials (GND_U
S
– Pin3) and (GND_UAux – Pin5) are
connected, unacceptable compensation currents can flow. In this case the
connection of a sensor at (Port X5–X8 --> Pin2) is not allowed!
The removal of the galvanic separation is not recommended.
