The NI PXI-2815 is a high-performance multiplexer module designed to deliver exceptional signal routing capabilities within demanding industrial environments. Engineered to meet the rigorous demands of the power industry, petrochemical sectors, and general automation, the PXI-2815 stands out as a versatile solution in National Instruments’ extensive portfolio of automation products. With its robust construction, impressive input/output capacity, and reliable switching performance, this module is ideal for complex test and measurement systems requiring precise signal control.

At its core, the NI PXI-2815 features 40 independent relays configured as 20 differential channels or 40 single-ended channels, enabling flexible multiplexing applications. These relays are capable of handling voltages up to 300 V and currents up to 1 A, making the module suitable for switching both low-level and moderate power signals without compromise. The PXI-2815’s mechanical relays ensure excellent contact resistance stability and long operational life, guaranteeing durability in continuous testing and automation workflows. Its PXI form factor ensures compatibility with PXI chassis, allowing seamless integration into larger modular systems.

One of the standout technical attributes of the PXI-2815 is its low crosstalk and high isolation between channels, which ensures signal integrity even when switching sensitive analog or digital signals. This feature is critical in the power industry and petrochemical applications where precise and accurate data acquisition and control are paramount. The module’s fast switching times and low channel-to-channel leakage also contribute to its reliability in high-throughput testing environments.

In real-world scenarios, the NI PXI-2815 excels in power industry applications such as substation automation and protective relay testing, where multiple signals from transformers, circuit breakers, and sensors must be routed accurately for diagnostics and monitoring. Similarly, in petrochemical plants, the PXI-2815 facilitates complex safety system testing by multiplexing numerous sensor inputs, enabling efficient validation of pressure, temperature, and flow measurement devices. For general automation tasks, the module’s adaptability supports the switching demands of robotics, manufacturing test stations, and control system verification.

When comparing the NI PXI-2815 to other National Instruments models, its unique combination of relay count, channel configuration, and voltage/current handling distinguishes it from alternatives like the NI PXI-2797, which offers different relay configurations more suited for low-voltage signal routing, or the NI PXI-6224, which focuses on data acquisition rather than multiplexing. Unlike digital I/O focused modules such as the NI PXle-6536 or NI PXI-6512, the PXI-2815’s mechanical relays provide superior isolation and signal integrity for analog switching. The PXI-2815 also complements modules like the NI PXI-6031E, an analog input module, by providing the flexible signal routing necessary before high-fidelity acquisition.

Alongside the NI PXI-2815, users can leverage other NI automation products to build comprehensive test systems. For instance, the NI USB-6210 and NI USB-6361 provide portable data acquisition and digital I/O capabilities, while the NI PCI-6601 offers high-speed counters and timers. The NI PXI-2530 and NI PXI-2523 are additional multiplexers catering to different channel counts and signal types, enabling tailored configurations. The NI PXle-4309 and NI PXle-4303 provide dynamic signal acquisition options that complement the PXI-2815’s switching capabilities. For scalable control systems, the NI cRIO-9054 embedded controller integrates seamlessly with PXI modules, expanding automation possibilities.

The application of PXI-2815 in power industry, petrochemical, and general automation environments is especially critical where reliability, signal integrity, and modularity are non-negotiable. Its ability to switch multiple high-voltage signals safely and efficiently makes it a cornerstone component in automated test and control architectures. Whether used in standalone test benches or integrated into sophisticated PXI chassis with other NI modules such as the NI PXI-6281 (high-accuracy analog inputs) or the NI PXI-6713 (arbitrary waveform generator), the PXI-2815 offers unmatched flexibility and performance.

In summary, the NI PXI-2815 combines high channel density, robust mechanical relay design, and excellent signal isolation, making it an indispensable asset within National Instruments’ suite of automation products. Its suitability for demanding applications in the power industry, petrochemical, and general automation sectors ensures that engineers and system integrators can rely on this module for precise, durable, and scalable signal switching solutions. Alongside complementary NI models like the NI SCXI-1128 signal conditioning module and the NI PXI-2797 multiplexer, the PXI-2815 fosters the creation of comprehensive, efficient, and future-proof test and automation systems.
