National Instruments USB-9234 Analog Input Module
The four-channel dynamic signal acquisition module USB-9234 (Part Numbers: 780235-01, 780235-02), manufactured by National Instruments, is designed to perform high-precision measurements from IEPE sensors. Because of its exceptional dynamic range, 24-bit ADC resolution, and high sampling rate of 51.2 kS/s per channel, it is well-suited for a wide range of industrial applications, including as machine status monitoring and noise, vibration, and harshness (NVH) testing in vehicles.
Accurate data collection is ensured by the software-selectable IEPE signal conditioning in this compact module, which supplies microphones and accelerometers with a steady 2 mA current. A broad range of signals may be accommodated by its ±5 V input range, and accurate measurements are guaranteed by the included anti-aliasing filters, which automatically adapt to the sampling rate.
The USB-9234 provides versatility for various sensor types and applications by supporting many input configurations, such as IEPE with AC coupling, AC coupling, and DC coupling. Its TEDS circuitry streamlines the setup and calibration procedures by enabling seamless connection with IEEE 1451.4 TEDS Class I sensors.
The USB-9234 guarantees simple integration into current settings with communication possibilities via BNC connectors. It may be used in severe industrial conditions since it can function in a wide temperature range of -40 °C to 70 °C. It also ensures energy economy with its low power consumption, with the active mode using a maximum of 900 mW and the sleep mode using only 25 μW.
In order to reject out-of-band signals and appropriately represent in-band signals, the module combines analog and digital filtering, improving data integrity. Passband ripple and phase nonlinearity for signals inside the passband are properties that guarantee accurate signal representation.
For coordinated sampling, the USB-9234 has an in-built master timebase that operates at 13.1072 MHz. This timebase may be synced with other modules. In addition to being flexible for a variety of settings and configurations, its compatibility with single-module USB carriers, NI CompactDAQ, and CompactRIO hardware makes it perfect for mobile or portable applications.
