Precautions for Correct Use
Always use separate power supplies for the Unit power supply and the I/O power supply. If you
supply power from the same power supply, noise may cause malfunctions.
The EtherCAT Coupler Unit supplies the NX Unit power and I/O power to the NX Units in the Slave Ter-
minal. The Units that are related to power supply for the NX Series other than the EtherCAT Coupler
Unit are listed in the following table.
For the specifications of NX-series power supply-related Units, refer to the
NX-series System Units
User’s Manual
(Cat. No. W523). For information on the most recent lineup of NX Series power sup-
ply-related Units, refer to NX-series catalogs or OMRON websites, or ask your OMRON representative.
I/O power supply This power supply drives the internal I/O circuits of the NX Units and it is used for the con-
nected external devices. This power supply is connected to the I/O power supply terminals on
the EtherCAT Coupler Unit. The I/O power is supplied to the NX Units from the I/O power sup-
ply terminals and through the NX bus connectors.

Supply Unit
This NX Unit provides NX Unit power supply.
This NX Unit is used when the total power consumption of the NX Units in the Slave
Terminal exceeds the NX Unit power supply capacity of the EtherCAT Coupler Unit.
The I/O power supply for the Additional NX Unit Power Supply Unit is connected to
the NX Unit on the left through the NX bus connector.
