NX-series Digital I/O Unit User's Manual (W521)
The name of the Unit.
The model of the Unit.
The number of output points provided by the Unit.
The type of terminal block and connector that is used for connecting the Unit. The number of termi-
nals on the terminal block is also described when a screwless clamping terminal block is used.
The I/O refreshing methods that are used by the Unit. Free-Run refreshing and synchronous I/O
refreshing are available.
The type of indicators on the Unit and the layout of those indicators.
The type of relay that is connected to the Unit. There are N.O. and N.O. + N.C..
The maximum value of switchable current of the connected relay.
The minimum value of switchable current of the connected relay.
The service life of the connected relay.
The delay time for which data in the internal circuit is reflected in the state of output elements of the
Unit. It is described according to the ON/OFF sequence.
The dimensions of the Unit. They are described as W x H x D. The unit is "mm".
The isolation method of the output circuit and internal circuit of the Unit.
The insulation resistance between the output circuit and internal circuit of the Unit.
The dielectric strength between the output circuit and internal circuit of the Unit.
The vibration-resistance specifications of the Unit. Some are different from the general specifica-
tions.
These are the shock-resistance specifications of the Unit. Some are different from the general
specifications.
The method for supplying I/O power to the Unit. The supply method is determined for each Unit.
The power is supplied from the NX bus or the external source.
The current capacity of the I/O power supply terminals (IOV/IOG) of the Unit. Do not exceed this
value when supplying the I/O power to the connected external devices.
The power consumption of the NX Unit power supply of the Unit.
The current consumption from I/O power supply of the Unit. The load current of any external con-
nection load and current consumption of any connected external devices are not included.
The weight of the Unit.
The output circuit layout of the Unit.
The installation orientation of the Slave Terminal including the Unit, and the details of restrictions
on the specifications due to the installation orientation.
A diagram of the connection between the Unit and connected external devices. When an I/O
Power Supply Connection Unit or a Shield Connection Unit is required to be connected to the con-
nected external devices, the description for such is included.
The function of the Unit to detect a disconnection/short-circuit.
The protective function that the Unit has.
