The NI PXIe-4331 high-speed bridge input module provides integrated data acquisition and signal conditioning for dynamic strain, load, and pressure measurements. This module includes increased accuracy, high data throughput, and synchronization features, making it ideal for high-density measurement systems.
The NI PXIe-4331 features eight channels with 24-bit analog-to-digital converters (ADCs) per channel for simultaneous sampling. This module supports 102.4 kS/s sampling rate for high-speed strain and bridge-based measurements. To remove noise, each module offers antialiasing and digital filters per channel. Each channel also features an independent programmable 0.625 to 10 V excitation voltage. Additionally, the NI PXIe-4331 provides remote sensing, internal bridge completion, and shunt calibration options per channel. The NI PXIe-4331 is intended to be used with the NI TB-4330 front-mounting terminal block for screw terminal connectivity.
As part of the PXI platform, these modules tightly synchronize with more than 1,500 PXI I/O instruments, such as NI X Series data acquisition modules and NI dynamic signal acquisition modules.

Choose from hundreds of specialized instruments to create a PXI System that suits your measurement needs and can scale for future applications. Then, we'll help you choose the right hardware and software to complete your configuration.
Add More Measurements and I/O Modules Use the PXI Advisor to choose from a variety of modules including analog I/O, digital I/O, switching and more. Then, complete and price the PXI System.
Preview a Complete System View and price a complete PXI configuration including the NI PXIe-4331, chassis, and controller. Starting from the default configuration, you can add modules, accessories, and software and customize your system.
Since your device does not have direct signal connectivity, you need a terminal block to act as an interface between your sensors/signals and your device. A terminal block provides easy access to the inputs and outputs of your hardware.
The chassis provides rugged, modular housing for the controller and modules and contains the high-performance PXI backplane, which includes the system's data, timing, and triggering buses.
The controller runs your application and interfaces with your PXI modules.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
