The isolation method between the input circuits and internal circuits and be-
tween the input circuits of the Unit.
The insulation resistance between the input circuits and internal circuits and
between the input circuits of the Unit.
The dielectric strength between the input circuits and internal circuits and be-
tween the input circuits of the Unit.
The method for supplying I/O power for the Unit. The supply method is deter-
mined for each Unit. The power is supplied only from the NX bus.
The current capacity of the I/O power supply terminals (IOV/IOG) of the Unit.
Do not exceed this value when you supply I/O power to external devices con-
nected to the trigger input terminals of the Unit.
The power consumption of the NX Unit power supply of the Unit. The power
consumption of the Unit connected to a CPU Unit and the power consumption
of the Unit connected to a Communications Coupler Unit are separately given.
The current consumption from I/O power supply of the Unit. This value does
not include the input current to the trigger input terminals and the current con-
sumption of external devices connected to the trigger input terminals.
The weight of the Unit.
The input circuit layout of the Unit.
The installation orientation of a CPU Unit containing the Unit and the installa-
tion orientation of a Slave Terminal containing the Unit. Any restrictions to
specifications that result from the installation orientation are also given.
ces. 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.
The function of the Unit to detect an input disconnection. It detects disconnec-
tions only when the input range is 1 to 5 V or 4 to 20 mA.
