NI PXI-2720I - PXI Programmable Resistor Module

The NI PXI-2720I is a high-performance, rugged PXI multiplexing switch module designed specifically to meet the demanding requirements of the power industry, petrochemical sector, and general automation applications. This module stands out for its exceptional input/output capacity, durability, and precision, making it an indispensable asset in complex test and measurement systems.

At its core, the NI PXI-2720I features 32 channels of high-density, high-reliability relay multiplexing, designed to handle a wide range of signal types with minimal crosstalk and high channel isolation. The module supports matrix and multiplexing configurations, enabling efficient routing of signals in automated test environments. Its durable electro-mechanical relays ensure long operational life, with a switching capacity that supports both low-level signals and higher voltage/current inputs, which is critical in power industry testing where signal integrity and reliability are paramount. The module’s switching speed and contact resistance are optimized for fast, repeatable measurements, ensuring that testing cycles in petrochemical plants or general automation lines are both swift and accurate.

In real-world scenarios, the NI PXI-2720I excels in applications such as automated functional testing of power converters, relay testing in substations, and signal routing in complex control systems within petrochemical plants. Its ability to handle diverse signal types and its robust construction allow it to perform reliably in harsh industrial environments. For example, in power industry applications, the PXI-2720I enables seamless switching between multiple sensors and measurement points without manual intervention, significantly reducing downtime and improving the precision of system diagnostics. Similarly, in general automation setups, it simplifies the integration of multiple test points, enabling scalable and flexible test architectures.

When comparing the NI PXI-2720I to other NI automation products, its unique advantage lies in its ruggedness combined with high channel density and flexible multiplexing capabilities. While modules like the NI PXI-6250 and NI PXI-4495 offer high-resolution data acquisition and precision analog I/O, they do not provide the same level of switching versatility. The NI PXI-2816 and NI PXI-2594 also offer multiplexing functions but with fewer channels and less rugged designs, making the PXI-2720I more suitable for industrial environments. In addition, the NI PXIe-6259 and NI PCI-6239 excel in data acquisition but lack the integrated relay switching capability that the PXI-2720I provides. This makes the PXI-2720I uniquely positioned as a switch module that can complement these DAQ modules, enabling complex system configurations where signal routing and data acquisition work seamlessly together.

Alongside the NI PXI-2720I, NI offers a broad portfolio of complementary products that enhance overall system performance. For instance, the NI PXIe-2727 can be used for high-speed digitizing in parallel with the PXI-2720I’s switching capabilities. The NI USB-6349 and NI PCI-6110 provide versatile data acquisition options for mixed-signal environments. For more specialized control needs, the NI PXI-6704 and NI PXI-6723 offer precision timing and synchronization modules that integrate well within PXI systems using the PXI-2720I. Additionally, the NI SCXI-1143 and SCXI-1314T provide signal conditioning solutions that can be paired with the PXI-2720I to ensure robust signal integrity in harsh industrial conditions. The NI cRIO-9048, with its real-time processing capabilities, can be integrated for advanced control and monitoring applications, enhancing automation workflows that utilize the PXI-2720I.

The application of PXI-2720I in power industry, petrochemical, and general automation settings is further enhanced by its compatibility with NI’s extensive software ecosystem, including NI LabVIEW and NI Switch Executive. These tools simplify the configuration, control, and maintenance of multiplexing and switching operations, reducing development time and improving system reliability. The PXI-2720I supports seamless integration into PXI chassis, offering scalability and modularity that are essential for evolving industrial automation needs.

In summary, the NI PXI-2720I is a robust, high-density multiplexing module tailored for demanding industrial applications. Its unique combination of input/output capacity, durability, and precision switching makes it a superior choice for power industry testing, petrochemical process monitoring, and general automation tasks. By integrating effectively with other NI automation products such as the NI PXIe-6259, NI PCI-6239, NI USB-6349, NI PXI-2816, NI SCXI-1143, and NI cRIO-9048, the PXI-2720I forms the backbone of sophisticated automated test and measurement systems designed to meet today’s industrial challenges.
