The National Instruments PXI-4472B is a high-performance PXI Sound and Vibration Module (Part Number: 778279-02) designed for versatile data acquisition applications. Featuring eight simultaneously sampled analog input channels, this module provides 24-bit resolution and supports both AC and DC coupling. With a maximum sampling rate of 102.4 kS/s and a low cutoff frequency of 0.5 Hz, the PXI-4472B employs delta-sigma modulation, allowing it to achieve high dynamic range while sampling input signals at an impressive 6.5536 MS/s when set to the effective data rate of 51.2 kS/s.

The PXI-4472B includes advanced analog trigger circuitry, enabling users to configure any input channel as a trigger source without hindering the acquisition capabilities of that channel. Users can initiate data collection based on specific signal thresholds, utilizing various triggering modes such as window triggering, analog edge triggering, and analog edge with hysteresis. These modes help manage incoming signal variations, providing flexibility to minimize noise and prevent inaccuracies in triggering.

The module operates with a maximum power requirement of 400 mA at +3.3 VDC, 2000 mA at +5 VDC, and 120 mA at both +12 VDC and -12 VDC. Compactly designed, the PXI-4472B measures 6.3 x 3.9 inches and weighs 8.5 ounces. It is suitable for operation in environments ranging from 0 to 55 °C and can be stored at temperatures between -20 to 70 °C. While the PXI-4472B has reached obsolete status from National Instruments, it remains available for purchase and repair through Apex Waves, ensuring continued support for your automation needs.
