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 EtherNet/IP Coupler Unit supplies the NX Unit power and I/O power to the NX Units in the Slave
Terminal. The Units that are related to power supply for the NX Series other than the EtherNet/IP Cou-
pler 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.
