National Instruments 778572-75 PXI Multiplexer Switch Module

The National Instruments 778572-75 is a high-density PXI multiplexer switch module found in the PXI-2575 Model series, intended for demanding automated test applications. This module efficiently and precisely routes multiple signals to and from source units or measurement devices thanks to its electromechanical relays. Relay monitoring and deterministic operation via hardware triggers are made possible by its innovative design, which includes onboard relay counting. This feature increases test throughput greatly.

The 778572-75 is an excellent choice for optimizing throughput through scanning since it can support up to 32,000 connections. By employing hardware triggers to cycle through a predefined list of connections, scanning removes host processor interruptions. Efficiency during testing is greatly increased by this smooth operation. Enhancing scanning performance by issuing triggers after every measurement is possible when the module is paired with devices such as the NI PXI-4070 FlexDMM.

Relay counts kept on the module can be retrieved and used, which means that the relay counting capability facilitates predictive maintenance. Through preemptive problem-solving using this data, users can lower unplanned system outages and improve overall dependability.

With a maximum switching voltage of 100 V channel-to-channel and channel-to-ground and a maximum switching power of 60 W per channel, the 778572-75 functions within strict electrical standards. It guarantees dependable performance in a variety of testing conditions because of its DC isolation resistance exceeding 1 GΩ and maximum total current of 1 A. This multiplexer switch module can accommodate a wide range of testing requirements with its support for numerous topologies, such as 1-wire 196 × 1, 2-wire 95 × 1, and 2-wire 98 × 1.

For smooth functionality and integration between switch modules, National Instruments offers complete software support for the 778572-75, including the IVI-compliant NI-SWITCH driver. Further improving usability and productivity is the easy environment provided by NI Switch Executive software for configuring, programming, and managing greater channel-count switching systems.
