• I/O terminals in the terminal connection diagrams are shown as viewed from the front of the Unit.
Dimensions
The external dimensions of the
Unit. Dimensions are given in
the following form: W × H × D.
The unit is mm.
Isolation method
The isolation method between the input
circuits and the internal circuits in the
Unit.
Insulation resistance
The insulation resistance
between the input circuits and
the internal circuits in the Unit.
Dielectric strength
The dielectric strength between the
input circuits and the internal circuits in
the Unit.
I/O power supply
method
The method that is used to
supply I/O power to the Unit.
The supply method is deter-
mined for each Unit. Power is
supplied either from the NX
bus or from an external source.
Current capacity of
I/O power supply
terminals
The current capacity of the I/O power
supply terminals (IOV/IOG) on the Unit.
You cannot exceed this value when you
supply I/O power to external devices
that are connected to the Unit.
NX Unit power con-
sumption
The power consumption of the
Unit from the NX Unit power
supply.
Current consump-
tion from I/O power
supply
The current consumption of the Unit
from the I/O power supply. The above
input current and the current consump-
tion of connected external devices are
not included.
Weight The weight of the Unit.
Circuit layout The circuit layout of the input circuits to the Unit.
Installation orientation
and restrictions The installation orientation of a Slave Terminal that includes this Unit. Any restrictions to specifi-
cations that result from the installation orientation are also given.
Terminal connection
diagram
The connection diagram between the Unit and external devices. Any I/O Power Supply Connec-
tion Units or Shield Connection Units that are required to connect the external devices are also
shown.
Failure detection
The failure detection functions
of the Unit.
Protection
The protection functions of the Unit.
