 Power Supply System with Through-wiring
An example is shown below. Connect the external power supplies to the power supply connector
(input) of one IO-Link Master Unit. Then, connect the power supply connector (output) of the Unit to
the power supply connector (input) of another IO-Link Master Unit with a power supply cable. In
this way, connect a power supply cable between the subsequent Units with through-wiring one after
another.
