Description
The National Instruments PXI-2531 PXI Matrix Switch Module, with part number 778572-31, falls under the category of PXI Switches. This module offers versatile topology options including a 1-wire dual 8 × 32 matrix, a 1-wire 8 × 64 matrix, and a 1-wire 4 × 128 matrix, catering to a wide range of application requirements.
It is designed to handle a switching/carry current of 0.5 A and can manage a maximum switching power of 10 W per channel. The module boasts a significant bandwidth of ≥20 MHz when used with a 50 Ω termination, ensuring minimal signal integrity loss over its operation.
With a focus on maintaining signal quality, the channel-to-channel crosstalk is exceptionally low, at <-70 dB, typical from 10 kHz to 100 kHz. This feature is crucial for applications requiring high signal fidelity and minimal interference between channels.
The module is equipped with 2 x 150 position Samter ERM8 Series I/O connectors, providing durable and reliable connections. Its mechanical relay life is rated at an impressive 1 x 109 cycles, indicating a long operational life and reducing the need for frequent replacements.
The relay actuating/release time is remarkably fast at 0.25 ms, allowing for quick switching operations. It supports up to 40 relays being driven simultaneously in PXI configurations, ensuring efficient multitasking capabilities.
