Caution!
Risk of destruction with external sensor supply!
The module infeed for the sensor supply U
S
may only be provided over the specified power
connection (Power X03/X04 >> U
S
+24 V/GND_U
S
) for the module. It is not permitted to supply
external power via the IO-Port (port X1 - X8 >> pin 1/pin 3) and this may destroy the module
electronics through power feedback.
Caution!
Do not compromise galvanic isolation through incorrect cabling!
The sensor supply (port X5 - X8 >> pin 1/pin 3) and extended sensor supply (port X5 - X8 >>
pin 2/pin 5) are galvanically isolated from each other. If the reference potentials (GND_
US
–
pin
3) and (GND_U
Aux
–
pin 5) are connected, excessive equalization currents may flow. In this
case, it is not permitted for a sensor to be connected to (port X5 - X8 >> pin 2)!
Eliminating the galvanic isolation is not recommended.
