A-1-3 Additional I/O Power Supply Unit - Omron Sysmac NX-PD1000 User Manual

Appendices
*1. You can use the unwired terminals of the Unit power supply terminals (UV/UG) for through-wiring of the Additional NX
Unit Power Supply Unit, to other CPU Units to which NX Unit can be connected or to the Unit power supply terminals on
another Communications Coupler Unit.
*2. The NC terminals are not connected to the internal circuits.

The name of the Unit.
The model of the Unit.
The type of terminal block and connector that is used for connecting the Unit. The
number of terminals on the terminal block is also described when a screwless
clamping terminal block is used.
The rated voltage and voltage range of the I/O power supply that is supplied to the
Unit.
The maximum value of the current that can be supplied to the Units from the I/O
power supply to be connected to the Unit through the NX bus connectors.
The current capacity of I/O power supply terminals of the Unit.
The dimensions of the Unit. They are described as W × H × D. The unit is "mm".
