NI PXI-2570 - PXI Relay Switch Module

The NI PXI-2570 is a high-density, 128-channel multiplexer module designed for precision signal routing in demanding automated test and measurement systems. Engineered for robustness and flexibility, the PXI-2570 stands out with its 1-pole and 2-wire switching capability, providing seamless input/output capacity that supports up to 128 single-ended channels or 64 differential channels. This enables complex signal routing in applications requiring high channel counts without compromising signal integrity.

Constructed with reliability in mind, the NI PXI-2570 features solid-state relays that offer exceptional durability and a long electrical life exceeding 10^9 operations. Its low contact resistance and minimal crosstalk ensure high-quality signal transmission, critical in industries like power generation, petrochemical processing, and general automation where precision and dependability are paramount. The module’s fast switching times and low power consumption further enhance system performance, allowing users to optimize throughput and efficiency in automated test environments.

In real-world scenarios, the NI PXI-2570 excels in the power industry by enabling comprehensive relay testing and power system validation, where accurate and repeatable switching is essential. In petrochemical plants, it facilitates the monitoring and control of complex sensor networks, ensuring safety and operational continuity. The module’s high channel density and reliability also make it ideal for general automation systems, where it can function as an integral component of large-scale signal routing architectures, reducing system footprint and cost.

Compared to other products in the NI portfolio, the PXI-2570 offers unique advantages. While modules like the NI PXI-2535 provide high-density matrix switching, the PXI-2570’s multiplexer design focuses on streamlined channel switching with improved signal isolation and lower crosstalk. Unlike the NI PXI-2813, which is optimized for RF switching, the PXI-2570 targets low-level analog signals with superior noise performance. When paired with data acquisition modules such as the NI PCI-6259 or NI USB-6349, the PXI-2570 enhances system versatility by enabling flexible signal routing before measurement, increasing overall test coverage.

Alongside the NI PXI-2570, NI offers complementary modules such as the NI PXI-2523 and NI PXI-2540 for additional multiplexing and switching configurations, as well as the NI PXle-6509 and NI PCle-6509 for digital I/O expansion. For high-precision data acquisition, modules like the NI PCI-6110 and NI PXI-6230 integrate seamlessly, providing a comprehensive solution for automated test systems. The NI SCXI-1314T and NI SCXI-1502 chassis expand system capabilities by supporting signal conditioning and multiplexing in specialized scenarios.

The application of PXI-2570 in power industry, petrochemical, and general automation environments highlights its adaptability and engineering excellence. It addresses the challenges of high channel density, signal integrity, and system reliability that are critical in these sectors. Whether used for relay testing in power grids, sensor multiplexing in petrochemical plants, or large-scale signal routing in automation systems, the NI PXI-2570 delivers dependable performance and scalability.

Incorporating the NI PXI-2570 into your test and measurement framework ensures access to NI automation products renowned for their precision, durability, and integration flexibility. With support for advanced software platforms and compatibility with a wide range of NI hardware, the PXI-2570 empowers engineers to build sophisticated, efficient test systems tailored to the evolving needs of the power, petrochemical, and automation industries.
