Warning:
IO Port – Sensor supply:
The sensor supply may only be carried out via the specified power
connection (Power X03 --> US +24 V/GND_U
S
) of the module. An
external power supply over the IO port (Port X1-X8 --> Pin1/Pin3) is
not permitted and can lead to a destruction of the module electronics!
Warning:
IO 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_US - 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.
