Item Specification
Safety output rated current This is the maximum load current for safety outputs on the Unit. The
inrush current of the external connection load must be lower than this
value.
Safety output ON residual voltage This is the residual voltage when a safety output on the Unit is ON.
Safety output OFF residual voltage This is the residual voltage when a safety output on the Unit is OFF.
Safety output leakage current This is the leakage current when a safety output on the Unit is OFF.
Dimensions (mm) These are the external dimensions of the Unit. The dimensions are giv-
en in the form W × H × D. The dimensions are given in millimeters.
Isolation method This is the method that is used to isolate the output circuits from the
internal circuits of the Unit.
Insulation resistance This is the insulation resistance between the output circuits and the in-
ternal circuits of the Unit.
Dielectric strength This is the dielectric strength between the output circuits and the inter-
nal circuits of the Unit.
I/O power supply method The method for supplying I/O power for the Unit.
Current capacity of I/O power sup-
ply terminal
This is the current capacity of the I/O power supply terminals (IOV/
IOG) on the Unit. When you supply I/O power to external devices that
are connected to the Unit, make sure that the total power does not ex-
ceed this value.
NX Unit power consumption This is the power consumption of the Unit from the NX bus power sup-
ply
.
Current consumption from I/O pow-
er supply
This is the current consumption of the Unit from the I/O power supply.
This value does not include the load current of any external connection
loads or the current consumption of any connected external devices.
W
eight This is the weight of the Unit.
Circuit layout This is the internal circuits of the Unit.
Terminal connection diagram This is the connection diagram between the Unit and external devices.
Installation orientation and restric-
tions
This is the installation orientation of the Unit. If the installation orienta-
tion imposes any restrictions on the specifications, those restrictions
are also described.
Protective functions These are the protective functions that are supported by the Unit.
