Additional I/O Power Sup-
ply Unit
This NX Unit provides additional I/O power supply.
Use this NX Unit in the following cases.
(a) When the I/O power supply capacity is insufficient
• When the total current consumption for the I/O power supply exceeds the max-
imum I/O power supply current of the EtherNet/IP Coupler Unit
• When a voltage drop in the I/O power supply causes the voltage of the I/O
power supply to go below the voltage specifications of the I/O circuits or con-
nected external devices
(b) Separating the I/O power supply
• When connected external devices have different I/O power supply voltages
• When separating the power supply systems
The NX Unit power supply of the Additional I/O Power Supply Unit is connected to
the NX Unit on the left through the NX bus connector.
