This document lists the I/O terminal summary and specifications for the NIPCI/PXI-6143.
For the most current edition of this document, refer to ni.com/manuals. Refer to the DAQ Quick Start Guide for more information about accessing documents on the NI-DAQ CD.
NoteWith NI-DAQmx, National Instruments has revised its terminal names so they are
easier to understand and more consistent among NI hardware and software products. The revised terminal names used in this document are usually similar to the names they replace. For a complete list of Traditional NI-DAQ terminal names and their NI-DAQmx equivalents, refer to the Terminal Name Equivalents table in the S Series Help.

Note: Accuracies are valid for measurements following an internal S Series calibration. Averaged numbers assume averaging of 100 single-channel readings. Measurement accuracies are listed for operational temperatures within ±1°C of internal calibration temperature and ±10 °C of external or factory-calibration temperature. NI recommends a one-year calibration interval. The Absolute Accuracy at Full Scale calculations were performed for a maximum range input after one year and 100points of averaged data.
