U3-HV vs U3-LV

# Low-voltage AINs:  16 12
# High-voltage AINs:  0  4
#DIOs  20  16


The U3-HV has the following differences versus the U3-LV:

  • First 4 flexible I/O are changed to dedicated HV analog inputs.
  • 4 HV inputs have ±10 volt or -10/+20 volt range.
  • 12 LV inputs (flexible I/O) still available, for 16 total analog inputs.

OEM Versions

The U3-LV-OEM or U3-HV-OEM includes the board only without the enclosure and without most through-hole components. See Section 2.12 of the U3 Datasheet for more information.
