Looping PROFINET and the supply voltage
Properties
The I/O device is equipped with one connector for the infeed and one socket for loop-through
of the supply voltage. The connector for infeed and the socket for loop-through are
interconnected internally.
The I/O device is equipped with two sockets for PROFINET IO. One socket is available for
the infeed and one socket for loop-through of the PROFINET IO.

Information on wiring
● If you are wiring your configuration, then you must take into account the impact of cable
length on the supply voltage to the ET 200eco PN (permissible tolerance).
● The maximum infeed current of the I/O device is 4 A for 1L+ non-switched and 4 A for
2L+ switched.
Those values must not be exceeded.
CAUTION
If you do not adhere to the maximum infeed currents and the cable cross-sections
required for these currents, you will risk overheating the cable insulation and contacts,
and damage to the device.
