NI PXI-2598 - PXI RF Switch Module

The NI PXI-2598 is a high-performance, rugged matrix switch module designed to meet the demanding requirements of industries such as the power sector, petrochemical plants, and general automation systems. Built on the robust PXI platform, the PXI-2598 offers a unique combination of reliability, versatility, and precision, making it an essential component in complex test and measurement setups.

At its core, the NI PXI-2598 features a 4x64 matrix switch configuration, providing 256 crosspoints with low crosstalk and high channel density. This configuration enables flexible routing of signals within test systems, allowing engineers to switch multiple inputs and outputs efficiently. The matrix supports a high bandwidth and low insertion loss, ensuring signal integrity for sensitive measurements. With a typical bandwidth of up to 200 MHz and a maximum switching voltage of 300 VDC/250 VAC, it is well-suited for a variety of signal types, including analog, digital, and mixed signals.

Durability is a standout characteristic of the PXI-2598. Engineered for extended operation in harsh environments, it features solid-state relays with a long lifecycle, often exceeding millions of switching operations. This reliability translates into reduced downtime and maintenance costs, critical in industrial automation and continuous monitoring applications. Moreover, the module is designed to operate within the stringent environmental standards of PXI chassis, including temperature ranges and vibration resistance, ensuring consistent performance in power plants and petrochemical facilities.

In real-world scenarios, the NI PXI-2598 excels in applications requiring complex signal routing and multiplexing. For instance, in the power industry, it can be integrated into automated test systems to monitor multiple sensors and control signals simultaneously, helping to ensure grid stability and safety compliance. In petrochemical plants, where hazardous conditions and complex control networks prevail, the PXI-2598 facilitates multiplexed signal acquisition from various instrumentation points, enhancing process control and fault diagnostics. General automation applications benefit from its high channel count and switching speed, enabling rapid reconfiguration of test sequences and reducing overall test cycle times.

When comparing the NI PXI-2598 to other NI automation products, it stands out for its matrix size and switching capacity. Unlike the NI PXI-2594, which offers a smaller matrix configuration, the PXI-2598’s expanded crosspoint count provides greater flexibility in routing complex signals. While other modules such as the NI PCI-6516 and NI USB-6341 focus on digital I/O and data acquisition, the PXI-2598 specializes in signal routing and switching within automated test environments. Additionally, modules like the NI PXI-2545 and NI PXI-2722 support multiplexing but do not match the PXI-2598’s combination of channel density and bandwidth, making the latter the preferred choice for high-density switching.

Alongside the NI PXI-2598, users can complement their test systems with other NI products such as the NI PXIe-4340 for high-performance digitizer capabilities, the NI PCI-6133 for analog input and output, and the NI PXI-2833 for waveform generation. The NI PXI-2549 can be used for additional multiplexed signal routing, while the NI PXI-2568 offers high-speed digital I/O capabilities enhancing overall system flexibility. The NI USB-6353 and NI PCI-6722 modules provide versatile data acquisition options that integrate seamlessly with PXI switching hardware like the PXI-2598. For control and monitoring applications, the NI cRIO-9043 embedded controllers and NI SCXI-1193 signal conditioning modules are ideal companions, enabling robust system architectures tailored to industrial requirements.

The application of PXI-2598 in power industry, petrochemical, and general automation sectors is well documented. Its ability to handle diverse signal types with precision switching reduces test times and increases throughput in automated setups. The modular nature of PXI combined with the PXI-2598’s high channel density allows for scalable solutions, accommodating future system expansions without significant redesign. Furthermore, integration with NI’s software ecosystem, including LabVIEW and TestStand, enhances usability, enabling engineers to develop custom switching sequences and automate complex test routines with ease.

In summary, the NI PXI-2598 is a vital asset within the NI automation products portfolio, delivering unmatched switching capabilities, durability, and adaptability. Its design is optimized for the rigorous demands of the power industry, petrochemical plants, and general automation, providing unparalleled control over signal routing in high-density test environments. Combined with complementary NI hardware such as the NI PXIe-4340, NI PCI-6133, and NI PXI-2549, it forms the backbone of sophisticated test and measurement systems that drive productivity and innovation across industries.
