NI 9239

The National Instruments 9239 is a 4-channel, 24-bit C Series analog input module for use in any NI CompactDAQ or CompactRIO chassis. The NI 9239 is similar to the NI 9229 in functionality except for the input range. You can find detailed specifications for the NI 9229 and NI 9239 in the same manual for comparison.

With channel-to-channel isolation, your entire system, including the device under test, is protected from harmful voltage spikes up to the isolation rating. In addition to safety, isolation eliminates measurement errors caused by ground loops because the front end of the module is floating.

The NI 9239 uses four 2-position screw-terminal connectors. The module includes all four connectors, and you can order more as replacements or for easy test equipment changes among devices under test. Those connectors are listed as model NI 9976

Strain-relief backshells for signal wire security and high-voltage protection (qty 4): NI 9971
Extra connectors for 2-position connector modules (qty 10): NI 9976
