This is the name of the Unit.
This is the model number of the Unit.
This is the number of safety I/O points that the Unit can control.
This is the capacity of the safety programs in the Unit.
This is the number of safety master connections that the Unit can have through
FSoE.
You can connect one Safety I/O Unit for each safety master connection.
This is the I/O refreshing method for the Unit. There are two methods: Free-Run
refreshing and synchronous I/O refreshing.
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 clamping terminal
block.
This gives the names and the layout of the indicators on the Unit.
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 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 connected 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 installation orientation of the Slave Terminal that includes this Unit. If
the installation orientation imposes any restrictions on the specifications, those
restrictions are also described.
