Figure 5-4 NXGPro+ User I/O Board
The 20 digital inputs are electrically isolated into five groups of four with a common low side
connection for each group. All terminals of the form C relays are available for the digital outputs.
The analog I/O are all individually isolated. The analog circuits are internally powered and do not
require a separate supply. In addition, the 0 to 10 V inputs provide an isolated 11 VDC supply for
the use of a 10 K Ohm potentiometer. While the circuits have a higher isolation rating, the actual
isolation is limited by the ratings of the connectors used (300 VAC). Actual usage of these
connections will depend on the individual wiring of the drive to the TB2 terminal strip. Refer to
the drive specific wiring diagrams.
While gain and offset adjustments of internal analog I/O is provided for in the software for
previous generations of equipment, the NXGpro user I/O boards do not require adjustment for
