National Instruments 783087-01 PXI Sound and Vibration Module

The part number 783087-01 from National Instruments is the identifying part number for the PXIe-4464 PXI Sound and Vibration Module. This module features 4 simultaneously sampled input channels that are configurable to differential or pseudodifferential with an 24 bit delta sigma analog to digital convertor. Its sampling rate ranges from 100 S/s to 204.8 kS/s with a resolution of less than 181.9 μS/s. Its FIFO buffer memory size is 1,023 samples with a data transfer technique of Direct memory access (DMA) and programmed I/O. The device supports AC/DC coupling, offering flexibility in measuring both alternating and direct current signals.

With a signal-to-noise ratio (SNR) of 119 dB, the 783087-01's strong dynamic range is one of its most notable characteristics. Because of its ability to detect even the smallest signals with the least amount of noise interference, it is perfect for applications that call for accurate measurement and analysis of vibration and sound data. In addition, the module provides six software-selectable input ranges, ranging from ±316 mV to ±42.4 V, so customers can customize the device to suit their own measuring requirements. 

This PXle module uses an onboard clock for timing and synchronization, and it can synchronize with other modules using the PXI backplane clock (PXIe_CLK100). For applications that need coordinated measurements across several channels or modules, this feature is essential. To power this module, 3.0 A current is required at +3.3 V and 2.0 A current at +12 V. Physically, this module has dimensions of 16 cm × 10 cm (6.3 in. × 3.9 in.) with a BNC female analog input connector and SMB male digital trigger connector. It weighs 260 g (9.2 oz).

The 783087-01 is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius with operating humidity of 10% to 90%, noncondensing and storage temperature of -20 degrees Celsius to 70 degrees Celsius with storage humidity of 5% to 95%, noncondensing. This module is intended for indoor use only and can be mounted at an altitude of 2000 meters with a pollution degree of 2.
