- 8-Channel, 51.2 kS/s/channel, -5 V to 5 V, C Series Sound and Vibration Input Module—The NI-9231 is a high-density sound and vibration module that can measure signals from integrated electronic piezoelectric (IEPE) and non-IEPE sensors such as accelerometers, tachometers, and proximity probes. It can perform the high dynamic range measurements necessary for modern measurement microphones and accelerometers and features simultaneous sampling. The NI-9231 incorporates both a TEDS input path and 2 mA of IEPE signal excitation source that can be turned on and off, removing the need for external sensor power and reducing the complexity of the data acquisition system.
