NI PXIe-4339 and RM-4339

NI PXIe-4339, 8 Ch, 24-Bit, Bridge and Voltage Input Module,
RM-4339 Rack-Mount Terminal Block

This document explains how to install, configure, and set up the NI PXIe-4339 SC Express 
universal bridge module and RM-4339 rack-mount terminal block. Driver support for the 
NI PXIe-4339 was first available in NI-DAQmx 14.2. Driver support for the RM-4339 was first 
available in NI-DAQmx 14.5. For the list of devices supported by a specific release, refer to the 

NI-DAQmx Readme

, available on the version-specific download page or installation media.

Note

The keying of these terminal blocks prevents them from connecting to other 

modules that could be damaged by the voltage present on the terminal block. 
However, you should only use these terminal blocks with their supported modules.
