NX-series System Units User’s Manual (W523)
*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 meanings of the items on the data sheet of the Additional I/O Power Supply Unit are explained in
the table below.
A-1-3
Additional I/O Power Supply Unit
Description of Items on the Data Sheet of the Additional I/O Power
Supply Unit
Item
Description
Unit name
The name of the Unit.
Model
The model of the Unit.
External connection ter-
minals
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.
Power supply voltage
The rated voltage and voltage range of the I/O power supply that is supplied to the
Unit.
Maximum current of I/O
power supply
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.
Current capacity of I/O
power supply terminal
The current capacity of I/O power supply terminals of the Unit.
Dimensions
The dimensions of the Unit. They are described as W × H × D. The unit is "mm".
Isolation method
The isolation method between the I/O power supply terminal and internal I/O power
supply of the Unit.
Insulation resistance
The insulation resistance between the external connection terminals and internal cir-
cuit of the Unit.
Dielectric strength
The dielectric strength between the external connection terminals and internal circuit
of the Unit.
NX Unit power con-
sumption
The power consumption of the NX Unit power supply of the Unit. The power con-
sumption when NX Units are connected to a CPU Unit and the power consumption
when NX Units are connected to a Communications Coupler Unit.
Current consumption
from I/O power supply
The current consumption from I/O power supply of the Unit.
Weight
The weight of the Unit.
Circuit layout
The circuit layout of the Unit.
Installation orientation
and restrictions
The installation orientation of a CPU Unit containing the Unit and the installation ori-
entation of a Slave Terminal containing the Unit. Any restrictions to specifications
that result from the installation orientation are also given.
Terminal connection dia-
gram
A diagram of the connection between the Unit and connected external devices.
When an I/O Power Supply Connection Unit or a Shield Connection Unit is required
to be connected to the connected external devices, the description for such is
included.
Overload/low voltage
detection
The function of the Unit to detect an overload and low voltage in the I/O power sup-
ply.
Protective function
The protective function that the Unit has.
