 Data Sheet | Specifications
The NI USB-9229 (±60 V) and USB-9239 (±10 V) are four-channel, 24-bit C Series modules designed to be both high-speed and accurate. These are ideal general-purpose analog input modules because of their resolution, sample rate, and input range.
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 USB-9229 and USB-9239 use four two-position screw-terminal connectors. The modules include 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 two-position connector modules (qty 10): NI 9976
