This is the name of the Unit.
This is the model number of the Unit.
This is the number of safety output points on the Unit.
This is the polarity that the Unit uses to connect to input devices. There are
models with NPN and PNP connections.
This is the maximum load current for outputs on the Unit. A specification is
given for each output and each Unit.
This is the rated voltage of the outputs on the Unit.
This is the number of safety slave connections that the Unit can have
through FSoE. You can connect to one Safety CPU Unit for each safety
slave connection.
This is the I/O refreshing method for the Unit. Only Free-Run refreshing is
supported.
This is the type of terminal block or connector that is used to wire the Unit.
This specification includes the number of terminals for a screwless clamp-
ing terminal block.
This gives the names and the layout of the indicators on the Unit.
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.
This is the residual voltage when a safety output on the Unit is ON.
This is the leakage current when a safety output on the Unit is OFF.
These are the external dimensions of the Unit. The dimensions are given in
the form W × H × D. The dimensions are given in millimeters.
This is the method that is used to isolate the output circuits from the internal
circuits of the Unit.
This is the insulation resistance between the output circuits and the internal
circuits of the Unit.
This is the dielectric strength between the output circuits and the internal
circuits of the Unit.
This is the method that is used to supply I/O power to the Unit. Each Unit
has its own method for supplying power. The power can be supplied either
from the NX bus or from an external source.
This is the current capacity of the I/O power supply terminals (IOV and IOG)
on the Unit. When you supply I/O power to external devices that are con-
nected to the Unit, make sure that the total power does not exceed this
value.
This is the power consumption of the Unit from the NX bus power 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.
This is the weight of the Unit.
This is the internal circuits of the Unit.
This is the connection diagram between the Unit and external devices.
This is the installation orientation of the Slave Terminal that includes this
Unit. If the installation orientation imposes any restrictions on the specifica-
tions, those restrictions are also described.
These are the protective functions that are supported by the Unit.
