NI PXI-2514 - PXI Fault Insertion Unit

The NI PXI-2514 is a high-performance, rugged PXI switching module specially designed to meet the demanding requirements of industries such as power, petrochemical, and general automation. Engineered with precision and reliability in mind, this module offers a unique combination of high channel density, superior signal integrity, and robust durability, making it an essential component in automated test systems and measurement setups.

At its core, the NI PXI-2514 features 32 channels of solid-state relays, providing fast, low-noise switching capabilities with minimal contact bounce. This input/output capacity enables complex multiplexing configurations, facilitating efficient routing of analog signals in environments where accuracy and repeatability are critical. The solid-state relay design enhances durability and lifespan by eliminating mechanical wear, a significant advantage in continuous or long-duration test applications. The PXI-2514 supports switching voltages up to 150 V DC/100 V AC and switching currents up to 0.5 A, ensuring compatibility with a wide range of signal types commonly encountered in power and petrochemical sectors.

Performance-wise, the PXI-2514 delivers rapid switching times typically under 1 ms, supporting high-throughput test sequences while maintaining low crosstalk and channel-to-channel isolation. This ensures signal integrity during sensitive measurements or control operations. Its robust construction withstands the environmental challenges often found in industrial settings, such as temperature fluctuations, vibration, and electrical noise, thereby guaranteeing reliable operation even under harsh conditions.

The application of PXI-2514 in the power industry includes testing and monitoring of transformers, relays, and circuit breakers, where precise switching and signal routing are paramount for accurate diagnostics and preventive maintenance. In petrochemical plants, the PXI-2514 excels in controlling and automating complex instrumentation arrays, enabling real-time data acquisition and control in hazardous or remote environments. Moreover, in general automation, it serves as the backbone for scalable test systems, offering flexibility for signal multiplexing in production line testing, quality assurance, and process control.

Compared to other NI automation products, the PXI-2514 stands out for its channel density and solid-state relay technology. While models like the NI PXI-2522 or NI PXI-2530 offer versatile switching options, they often rely on mechanical relays, which may introduce latency and reduce longevity in continuous-use scenarios. The NI PXI-2514’s solid-state approach significantly reduces maintenance needs and enhances switching speed. Additionally, unlike the NI PXI-2541 and NI PXI-2555 which focus on different switching topologies, the PXI-2514 provides a balance of density and performance optimized for mid-range voltage and current applications.

Alongside the NI PXI-2514, National Instruments offers a broad portfolio of complementary modules to build comprehensive automated systems. For high-precision analog input/output, the NI PXIe-6341 and NI PCI-6010 provide reliable data acquisition capabilities. The NI PXI-6608 offers programmable digital I/O, ideal for synchronization and control tasks, while the NI PXI-6070E and NI PCI-6239 deliver enhanced analog measurement performance for demanding test requirements. For switching and signal routing beyond the PXI-2514’s scope, the NI PXI-6733 and NI PXle-6356 offer specialized capabilities in higher voltage or current ranges. The NI USB-6349 and NI USB-6229 extend system flexibility by enabling portable and compact measurement solutions complementing PXI-based setups.

In summary, the NI PXI-2514 is a critical module in the NI automation product suite, perfectly suited for applications requiring reliable, rapid, and high-density switching. Its design specifically addresses the needs of the power industry, petrochemical sector, and general automation fields, where precision and durability cannot be compromised.
