The name of the Unit.
The model of the Unit.
The number of input 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, synchronous I/O
refreshing and input refreshing with input changed time are available.
The type of indicators on the Unit and the layout of those indicators.
The polarity of the input devices that are connected to the Unit. NPN connection and PNP connec-
tion are available.
The rated input voltage and range of the Unit.
The input current at the rated voltage of the Unit.
The input voltage in which the Unit input turns OFF, and corresponding input current.
The delay time for which the status change of the input terminals reaches the internal circuit of the
Unit.The input filter time below is not included. It is described according to the ON/OFF sequence.
The filter time when the status of the internal circuit is read as the data to the internal of the Unit. It
is same for both ON/OFF. The filter time to be set by the Support Software is described.
The dimensions of the Unit. They are described as W x H x D. The unit is "mm".
The isolation method between the input circuit and internal circuit of the Unit.
The insulation resistance between the input circuit and internal circuit of the Unit.
The dielectric strength between the input circuit and internal circuit of the Unit.
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 power supply terminals 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 above input current and current
consumption of any connected external devices are excluded.
The weight of the Unit.
The input 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.
