Precautions for Correct Use
Always use separate power supplies for the Unit power supply and the IO power supply. If you
supply power from the same power supply, noise may cause malfunctions.
The PROFINET Coupler Unit supplies the NX Unit power and IO power to the NX Units in the IO Device
Terminal. The Units that are related to power supply for the NX Series other than the PROFINET 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.
