NI PXI-2797 - PXI RF Switch Module

The NI PXI-2797 is a high-performance PXI chassis designed to meet the rigorous demands of power industry, petrochemical, and general automation applications. Engineered with durability and scalability in mind, this modular chassis offers an optimum balance of input/output capacity, robust performance, and flexibility, making it a cornerstone for complex test and measurement systems.

At its core, the NI PXI-2797 features a 19-slot PXI Express chassis, delivering a high-bandwidth backplane capable of supporting data transfer rates up to 4 GB/s per slot. This makes it ideal for applications requiring rapid data acquisition and processing, such as power grid monitoring or petrochemical plant automation where real-time control and precision are critical. The chassis supports mixed 3U and 6U PXI and PXI Express modules, providing exceptional versatility for integrating multiple measurement and control instruments into a single system.

Durability is a key highlight of the PXI-2797. Built with industrial-grade components and a rugged frame, it withstands harsh environments typical of petrochemical plants and power generation facilities. Its advanced thermal management system ensures optimal cooling for extended operation without compromising performance or reliability. This makes the PXI-2797 well-suited for continuous use in demanding general automation tasks, where system uptime is paramount.

The NI PXI-2797 excels in real-world scenarios such as automated testing for power converters, monitoring of turbine control systems, and process automation in chemical plants. Its high slot count and bandwidth allow engineers to consolidate multiple instruments—such as the NI PXI-6221 for multifunction data acquisition, the NI PXI-2532 for matrix switching, and the NI PXI-6513 for digital I/O—into one compact system. This integration capability reduces system complexity and improves data synchronization, essential for high-precision control and diagnostics.

When compared to other NI automation products, the PXI-2797 stands out due to its combination of slot density and PXI Express bandwidth. For example, while the NI PXI-1052 offers a smaller 8-slot configuration suitable for less complex setups, the PXI-2797’s 19-slot capacity provides greater expansion potential for future-proofing systems. Compared to the NI PXI-2520, which supports only PXI modules, the PXI-2797’s support for both PXI and PXI Express modules offers a significant performance edge, particularly in applications requiring high-speed digitizers like the NI PXI-6133 or the NI PXI-2817 oscilloscope module.

Alongside the NI PXI-2797, complementary NI models such as the NI PCI-6509 and NI PCI-6111 provide robust digital and analog I/O capabilities for desktop or embedded control scenarios. The NI PXI-2570 and NI PXI-2590 offer versatile switching solutions that integrate seamlessly within the PXI-2797 chassis, enabling complex routing and multiplexing operations required in automated test systems. For high-precision analog input, the NI PXI-6239 and NI PCle-6346 data acquisition cards bring enhanced resolution and sampling rates, further expanding the PXI-2797’s application scope.

In terms of application, the PXI-2797 is particularly valuable in the power industry, where it can support the development and testing of smart grid technologies, protection relays, and power electronics. Its rugged design and high-speed data paths are equally advantageous in petrochemical plants for monitoring process variables and automating control loops with minimal latency. In general automation, the PXI-2797’s modular architecture supports diverse instrumentation needs—from environmental monitoring to complex manufacturing test systems—making it a versatile solution for engineers seeking reliability and scalability.

In summary, the NI PXI-2797 chassis is a premium choice within NI automation products, blending high input/output capacity, durability, and superior performance. Its ability to integrate seamlessly with a broad range of NI modules such as the NI PXI-2596, NI PXI-2865, NI SCXI-1129, and NI PXle-2529 enhances system flexibility and future readiness. Whether used in the power industry, petrochemical sector, or general automation, the PXI-2797 delivers the robustness and speed required to meet evolving industrial challenges, making it an essential platform for cutting-edge test and measurement solutions.
