NI 6132/6133 Specifications

This document lists the I/O terminal summary and specifications for the NI 6132/6133.

For the most current edition of this document, refer to ni.com/manuals. Refer to the DAQ Getting Started Guide for more

information about accessing documents on the NI-DAQ CD.

Note

With 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.
