2 SYSTEM CONFIGURATION
REMARK
When supplying power from one power source to multiple remote I/O modules, select the cable
and perform the wiring with considerations to the voltage decline from the cables.
Connections can be established if the remote I/O module's receiving port voltage is within the
specification range of the used remote I/O module.
(b) Countermeasure for mis-input
Wire the power supply cable for the power supply module, stabilized power,
and input/external-supply power of the AC input from the same power
source.
