The NI PXIe-7846 (Part Number: 784143-01) is a high-performance R Series Multifunction Reconfigurable I\/O (RIO) module engineered by National Instruments for PXI Express systems. Powered by a robust, user-programmable Kintex-7 160T FPGA, this advanced instrument enables engineers to execute complex onboard signal processing and achieve direct, deterministic control over I\/O signals. It serves as a superior alternative to standard data acquisition hardware by offering complete flexibility over system timing and synchronization.<\/p>\n
Engineered for ultimate adaptability, the PXIe-7846 natively integrates with the LabVIEW FPGA Module. This empowers test engineers to develop highly specialized applications requiring microsecond-level timing precision. Its custom programmable architecture unlocks capabilities that are often impossible with typical DAQ devices, such as independent multirate sampling, individual channel triggering, and the execution of highly specialized custom communication protocols on the fly.<\/p>\n
The architectural advantage of the PXIe-7846 lies in its dedicated analog-to-digital converter (ADC) per channel. By eliminating multiplexing delays, it guarantees true simultaneous sampling and independent timing for each input. Furthermore, the module supports high-throughput peer-to-peer (P2P) streaming, allowing it to bypass the host CPU and transfer continuous data streams directly to other PXI Express modules for real-time analysis or high-speed data logging.<\/p>\n
Built for massive I\/O density and uncompromising speed, the PXIe-7846 delivers 8 analog input channels capable of operating at 500 kS\/s per channel with 16-bit resolution, alongside 8 analog output channels that boast a 1 MS\/s maximum update rate. For digital operations, it features an impressive 48 bidirectional digital I\/O channels. These digital lines are divided into 16 low-speed channels running up to 10 MHz and 32 high-speed channels capable of handling 80 MHz signal frequencies, all featuring software-selectable logic levels ranging from 1.2 V to 3.3 V.<\/p>\n
On the physical layer, the PXIe-7846 provides secure connectivity via two rugged 68-pin VHDCI type connectors. The hardware is designed for industrial resilience, featuring robust overvoltage protection up to \u00b142 V for analog inputs and \u00b115 V for analog outputs. Additionally, the module allows engineers to configure user-defined power-on and power-off states, ensuring that external circuitry remains safe during system initialization and shutdown.<\/p>\n
The PXIe-7846 is meticulously tailored for engineering applications where dynamic control and extreme determinism are non-negotiable. It is widely deployed as a core hardware foundation for hardware-in-the-loop (HIL) testing, rapid control prototyping, complex sensor simulation, and high-speed motion control. Its ability to seamlessly bridge real-time FPGA logic with versatile physical I\/O makes it an invaluable asset in aerospace, automotive validation, and advanced scientific research.<\/p>\n
Overall, the National Instruments PXIe-7846 Multifunction Reconfigurable I\/O Module is an elite hardware solution for engineers who prioritize absolute timing control, parallel I\/O execution, and deep software integration. With its Kintex-7 FPGA, dedicated ADCs, and peer-to-peer streaming capabilities, the PXIe-7846 provides a definitive, future-proof platform for building high-performance, deterministic automated test systems.<\/p>","protected":false},"excerpt":{"rendered":"
