NI PXI-2567 - PXI Relay Driver Module

The NI PXI-2567 is a high-performance 40-channel multiplexer module designed to deliver exceptional signal switching capabilities, making it a standout choice for demanding test and measurement applications. With its robust architecture, the PXI-2567 supports a maximum switching voltage of up to 300 VDC/250 VAC and a maximum switching current of 1 A per channel, ensuring reliable operation in environments where precision and durability are critical. Its low channel-to-channel crosstalk and low thermal EMF contribute to accurate measurements, while the high switching speed of the PXI-2567 minimizes test cycle times, enhancing overall system efficiency.

Built for durability, the NI PXI-2567 features solid-state relays that offer extended life cycles and robust performance in harsh industrial settings. This makes it ideal for continuous operation in sectors such as the power industry, petrochemical plants, and general automation systems. The module’s compact PXI form factor enables seamless integration into existing PXI chassis, leveraging the high bandwidth and synchronization capabilities inherent in NI PXI platforms.

In real-world applications, the NI PXI-2567 excels in scenarios requiring rapid, reliable multiplexing of analog signals. For instance, in the power industry, it facilitates efficient testing of protective relays and switchgear by enabling quick channel switching without signal degradation. Similarly, in petrochemical process automation, the PXI-2567 supports monitoring and control systems by multiplexing sensor inputs with high accuracy, ensuring real-time data acquisition and process safety. Within general automation, it is equally valuable for automated test equipment (ATE) setups that demand flexibility and precision in signal routing.

When compared with other models in the NI automation product lineup, the PXI-2567 offers unique advantages. Unlike the NI PXI-6514, which focuses on digital I/O capabilities, or the NI PXI-6251 that specializes in multifunction DAQ, the PXI-2567’s emphasis on multiplexed analog signal switching sets it apart. While the NI PXI-2569 provides matrix switching for more complex switching topologies, the PXI-2567 is optimized for high-density, high-speed multiplexing, making it more suitable for applications where channel count and switching speed are paramount. Its solid-state relay technology also offers greater durability over mechanical relay-based modules such as the NI PXI-2534.

Alongside the NI PXI-2567, NI offers complementary modules such as the NI PXI-1050 chassis for system integration, the NI PXle-4322 for high-fidelity analog input, and the NI PXI-6132 for precision data acquisition. For enhanced digital interfacing, modules like the NI PCI-6521 and NI PXI-6533 provide robust digital I/O options. The NI USB-6003 and NI USB-6255 extend the flexibility of NI’s portfolio for portable and desktop applications, while the NI PXI-2594 offers additional matrix switching capabilities for complex test architectures. Furthermore, the NI PXle-6341 supports multifunction DAQ with embedded signal conditioning, complementing the PXI-2567’s switching capabilities. The NI PXI-2512, another multiplexing module, offers alternative switching configurations, broadening the suite of options for system designers.

The application of PXI-2567 in power industry, petrochemical, and general automation environments is well recognized due to its ability to handle high channel counts with precision and reliability. Its integration with NI automation products like the PXI-6608 timing and synchronization module ensures tightly coordinated test sequences, while the PXI-6070E provides additional analog input capacity for comprehensive system monitoring.

In summary, the NI PXI-2567 stands as a versatile and reliable solution for multiplexing needs in demanding industrial applications. Its balance of high channel density, fast switching speeds, and durability positions it as a preferred choice among NI automation products. Whether deployed in power system testing, petrochemical process control, or general automation testing, the PXI-2567 delivers the performance and flexibility required to optimize test and measurement workflows. With its seamless compatibility with a broad range of NI modules such as the PXI-6514, PXI-6251, PXI-1050, PXI-2594, and USB-6003, system architects can create tailored solutions that meet the most stringent industrial requirements while benefiting from NI’s proven hardware ecosystem.
