[1] Operating channels in NRSE input mode while outside of the specified voltage range may impact accuracy of other channels.

[2] The minimum measurement voltage range is the largest voltage the NI PXIe-7866 is guaranteed to accurately measure.

[3] The minimum measurement voltage range is the largest voltage the NI PXIe-7866 is guaranteed to accurately measure.

[4] Tristate by default.

[5] Only protects up to 20 lines simultaneously. NI recommends minimizing long-term over/undervoltage exposure to the Digital I/O. Prolonged DC voltage stresses that violate the maximum and minimum digital input voltage ratings may reduce device longevity. Over/under-voltage stresses are considered prolonged if the cumulative time in the abnormal condition exceeds 1 year.
