Description
The NI 9250 with part number 783827-01 falls under the C Series Analog Input category. This model is specifically designed for sound and vibration measurements, providing a 2-Channel Analog Input module that is equipped with BNC connectivity. It supports a wide range of sensors including IEPE, non-IEPE sensors such as microphones and accelerometers, and even TEDS enabled devices, offering flexibility in various applications.
The NI 9250 features an input range of ±5 V, ensuring precise measurements across a variety of signal types. It boasts a maximum sample rate of 102.4 kS/s per channel, allowing for high-resolution data acquisition. This module is equipped with IEPE signal conditioning, which includes software-selectable AC/DC coupling, ensuring optimal performance with IEPE sensors.
Additionally, the module includes integrated anti-aliasing filters, which are software-adjustable to the sample rate, enhancing the quality of the measurements by reducing signal noise. The IEPE excitation source can be enabled or disabled through software, providing further versatility in accommodating different types of sensors.
The NI 9250 utilizes a 24-bit Delta-Sigma ADC with analog pre-filtering, guaranteeing high accuracy in signal conversion. To protect against potential damage from unexpected voltage spikes, it offers overvoltage protection of up to ±30 V (one channel at a time), ensuring the longevity and reliability of the module.
