The NI ‑ 9239 module is used for differential analog acquisition. The channel-to-channel insulation ensures that the entire system, including the test objects, is protected from dangerous voltage peaks within the insulation voltage. In addition, the insulation prevents measurement errors that arise due to ground loops, since the front end of the module is floating. The resolution, sampling rate and input range make the NI ‑ 9239 an effective, all-purpose analog module that is particularly suitable for applications that require high speed and accuracy.
