Additional I/O Power
Supply Unit*3
Use a two-conductor
shielded twisted-pair
cable. Do not ground
the shield.
To use current input,
connect SHT□+ and
SHT□- with a
short-circuit cable.*4

When the input range is 1 to 5 V or 4 to 20 mA: Supported

Other input range: Not supported
*1.
This is the minimum value. The Units perform conversion in the sampling period determined based on the Number of
Samplings Setting. The sampling period must be set to this value or longer.
*2.
The following Unit cannot be connected next to the Unit.

*3.
Besides the Additional I/O Power Supply Unit, there are Units that can supply I/O power to the NX bus. For example,
you can use a Connected Communications Coupler Unit. If you use this Unit to supply I/O power to the High-speed
Analog Input Units, the Additional I/O Power Supply Unit is unnecessary. The Additional I/O Power Supply Unit is also
unnecessary if you do not use the trigger inputs of the High-speed Analog Input Units.
*4.
Short-circuit cables are not included in the product. The cable length must be 4 cm or less and allow for wiring to the
screwless clamping terminal block. Be sure to use cables and ferrules that are applicable to the screwless clamping
terminal block.
If the cable is too long, the analog input values may not be accurate.
*5.
To use this function, set the Disconnection Detection Enable/Disable to Enable.
