National Instruments 784277-01 Sound and Vibration Module
The National Instruments 784277-01 is a compact 6-input sound and vibration module. It is also identified as the PXIe-4480 and is engineered for precise high-bandwidth audio, acoustic, and vibration measurements. It provides 6 x channels of dynamic signal acquisition, each independently configurable through software for voltage or charge measurements. It supports a broad sample rate range from 100 samples per second to 1.25 MS/s due to its 24-bit Delta-Sigma A/D converter. It caters to various application needs such as audio testing, NVH analysis, and underwater acoustic measurements.
The 784277-01 module features software-selectable input configurations that allows for either differential or pseudodifferential settings in voltage mode, and single-ended configurations in charge mode. Users can also choose between AC or DC coupling for voltage measurements, with AC coupling available for charge measurements. This flexibility is crucial for adapting to different sensor types that includes hydrophones, pressure sensors, and acoustic transducers. The 784277-01 also includes IEPE excitation and TEDS support. The NI 784277-01 can sample at rates up to 20 MS/s per channel that makes it ideal for capturing high-speed events such as blasts and pressure spikes. The module supports 4 x selectable gain settings for input range configuration. Overvoltage protection of this unit is exceptional and it offers protection levels up to ±30 V for differential inputs, and ±15 V for charge inputs.
The physical design of the 784277-01 unit adheres to the x4 PXI Express peripheral module specifications while fitting seamlessly into PXI Express or hybrid slots. The unit measures 16 cm x 10 cm (6.3 in. x 3.9 in.) in size and weighs only 264 g (9.3 oz.). It features an InfiniBand 12x analog input connector and an SMB male digital trigger connector on the front panel along with LEDs indicating access and activity status. The 784277-01 module is built to withstand a range of environmental conditions, with an operating temperature range from 0 °C to 55 °C. It also meets rigorous shock and vibration standards. It supports a two-year external calibration interval.
Safety and electromagnetic compatibility (EMC) standards compliance are integral to the 784277-01’s design, meeting requirements such as IEC 61010-1 and EN 61326-1. This makes it suitable for use in controlled environments requiring precise and reliable measurements. The module's design prioritizes user safety along with clear cautions against connecting to signals in higher measurement categories.
