The National Instruments NI 9234 is a high-precision 4-channel C Series module designed for sound and vibration measurements in industrial and research applications. Part of NI's CompactDAQ or CompactRIO systems, it offers simultaneous IEPE (Integrated Electronics Piezoelectric) signal conditioning for accelerometers and microphones, making it ideal for predictive maintenance, machine health monitoring, and acoustic testing.

• 4 Analog Input Channels: Simultaneously sample IEPE sensors at up to 51.2 kS/s/ch.
• IEPE Signal Conditioning: Built-in current source (2 mA or 4 mA) for accelerometers and microphones.
• Wide Dynamic Range: 24-bit ADC resolution with ±10V input range.
• Anti-Aliasing Filters: Programmable cutoff frequencies (5 kHz, 10 kHz, 20 kHz) to prevent signal distortion.
• Compact Design: C Series form factor (34 mm x 100 mm x 12 mm) for portable or embedded systems.
• Software Integration: Seamless compatibility with NI LabVIEW, MATLAB, and Python for data analysis.
