NI PXI-2813 - PXI Digital I/O Switch Module

The NI PXI-2813 is a high-performance, robust PXI relay module designed for demanding applications in the power industry, petrochemical sectors, and general automation environments. Engineered to deliver exceptional reliability and precision, the PXI-2813 provides a versatile switching solution capable of handling a wide range of signal types with excellent durability and low contact resistance. This model is especially suited for complex test systems requiring high channel density and flexible relay configurations.

One of the standout technical features of the NI PXI-2813 is its extensive input/output capacity. The module supports up to 64 single-pole double-throw (SPDT) relays, enabling comprehensive switching capabilities in a compact 3U PXI form factor. Each relay is designed to handle up to 2 A at 30 VDC or 0.5 A at 110 VAC, which ensures compatibility with a broad spectrum of signal levels commonly encountered in industrial and automation applications. The PXI-2813’s low thermal EMF and contact resistance contribute to precise measurements and signal integrity, critical for high-accuracy test setups.

Durability is a key strength of the PXI-2813. The relays are rated for over one million operations, providing long service life even in high-cycle environments. This endurance makes the PXI-2813 an ideal choice for automated test systems where downtime must be minimized. Additionally, its mechanical stability and robust connector design help withstand the rigors of industrial environments such as power plants and petrochemical processing facilities.

In terms of performance metrics, the NI PXI-2813 offers fast switching times, typically around 5 ms per relay operation, supporting rapid test sequences and minimizing overall test time. The module also excels in noise immunity, which is essential when operating in electrically noisy environments typical of power generation and petrochemical plants.

Real-world applications of the NI PXI-2813 demonstrate its versatility and reliability. In the power industry, it is commonly used for automated relay testing, contact resistance measurements, and signal routing in protection relay test systems. Petrochemical plants leverage the PXI-2813 for monitoring and control applications, where precise signal switching and robust operation under harsh conditions are critical. In general automation, the PXI-2813 integrates seamlessly into systems that require flexible switching schemes, including manufacturing test stations and research laboratories.

When comparing the PXI-2813 to other NI automation products, its high relay density and durability distinguish it from models like the NI PXI-2576, which offers fewer channels but supports higher voltage switching, or the NI PXI-2556, optimized for low-level switching applications. Unlike the NI PXIe-6375, which focuses on analog input measurements with high-speed digitization, the PXI-2813 is specialized for switching tasks, making it an indispensable component in modular test setups.

Alongside the NI PXI-2813, NI offers complementary modules such as the NI PXI-6132 for high-speed data acquisition, NI PXI-6224 for versatile analog input/output, and the NI SCXI-1600 chassis for signal conditioning and expansion. The NI USB-6509 and NI USB-6351 provide portable I/O options that integrate well with PXI-based systems, while the NI cRIO-9049 and NI cRIO-9040 offer reconfigurable embedded control solutions perfect for hybrid automated test and control applications. For specialized switching needs, the NI PXI-2816 offers a higher voltage relay option, and the NI PXI-2799 provides a compact high-density switching solution. The NI PXIe-6251 complements this lineup with multifunction DAQ capabilities that enhance overall system flexibility.

In summary, the NI PXI-2813 stands out as a durable, high-density relay module tailored for complex switching tasks in power industry, petrochemical, and general automation applications. Its combination of high channel count, long relay life, fast switching speed, and robust performance makes it a preferred choice for engineers and system integrators seeking reliable, scalable PXI solutions. Alongside a broad ecosystem of NI automation products, the PXI-2813 enables the design and deployment of efficient, precise, and resilient automated test systems that meet the rigorous demands of modern industrial environments.
