Pin 5
The 7/8" plug is designed for a maximum current of 9 A per pin. This must be taken into account when looping
the supply voltage.
The switch must be connected to a power supply of 18 to 32 V DC. The U
System/Sensor
supplies the connection
with voltage and the U
Digital I/O
provides the power supply of the digital I/O ports.
The voltage of the U
System
must not be switched off during ongoing operation and hence must not be con-
ducted via emergency stop circuits, since otherwise the switch and all connected Ethernet products will not be
able to participate in the communication.
