Description
The National Instruments PXI-2575 PXI Multiplexer Switch Module, with part number 191703A-01 (778572-75), falls under the category of PXI Switches. This module is designed to facilitate various configurations through its topology options, which include 1-wire 196 x 1, 2-wire 95 x 1, and 2-wire 98 x 1 multiplexer configurations. It is built using electromechanical, socketed relays to ensure durability and reliability in switching operations.
The electrical life of these relays is impressive, with approximately 105 operations at rated load, contributing to the module’s longevity and performance consistency. The PXI-2575 boasts a switch bandwidth of 20 MHz and can handle a maximum switching power up to 60 W, 62.5 VA (DC to 60 Hz) per channel, making it versatile for a wide range of applications. Additionally, it features a relay count tracking feature, enhancing its operational efficiency and reliability.
Connection to the module is facilitated through a 200 POS LFH Matrix 50 I/O connector, ensuring a secure and reliable interface. However, it is important to note that this module is not recommended for 2-wire resistance measurements, indicating its specialized application scope. The module’s relays have a typical operating time of 1 ms and a maximum operating time of 3.4 ms, with relay contacts made from silver, gold covered materials for optimal performance and durability.
With a scan rate of 140 cycles per second, this module provides efficient and rapid switching capabilities. It is compatible with a variety of software, including NI-SWITCH, NI-DAQmx, Measurement Studio for Visual C++, NI Switch Executive, LabWindows/CVI, and LabVIEW, offering flexibility in programming and integration into existing systems. For physical connectivity, it supports cable types such as 1 m SH200LFH-4xDB50F-S and
