3.9 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 feed connector and the socket for loop-through are interconnected
internally.
Two sockets for PROFINET IO are available on the I/O device. One socket for the infeed and
one socket for loop-through of the PROFINET IO.

Information on wiring
• Always make allowances for the influence of the cable length on the supply voltage at
your ET 200eco PN (permitted tolerance) when you wire your configuration.
• The maximum infeed current of the I/O module is 4 A each for 1L+ non-switched and 2L+
switched.
These values may not be exceeded.
CAUTION
Adhering to the maximum infeed currents and cable cross-sections
If you do not maintain the maximum infeed currents and the appropriate cable cross-sec­
tions, you will risk overheating of the cable insulation and contacts, and damage to the
device.
