National Instruments 778572-27 PXI Multiplexer Switch Module
The National Instruments 778572-27 is a high-voltage PXI multiplexer switch module that is a member of the PXI-2527 product range. This 32-channel, 300 V, 2-wire switch module is outfitted with high-power electromechanical relays and is intended for medium-to high-density automated test applications. It's the perfect front end for PXI Digital Multimeters (DMMs), such the NI 407x FlexDMM. It makes it easy to expand the channel across different measurement configurations, like 64x1 1-wire, 32x1 2-wire, and 16x1 4-wire setups.
With the use of scanning capabilities, the 778572-27 module greatly increases throughput in automated testing. To minimize disruptions from the host CPU, it can download a list of up to 32,000 connections and use hardware triggers to cycle between them. Using instruments such as the NI 407x FlexDMM, which activates the multiplexer following every measurement, makes this scanning procedure extremely effective.
The 778572-27 has inbuilt relay counting, which keeps track of each relay's actuations in order to enhance system efficiency and guarantee dependability. Users can reduce unexpected system downtime and enable predictive maintenance by using this functionality, which enables users to collect relay numbers programmatically.
Signal connections for the 778572-27 are made via the TB-2627 front-mounting screw-terminal block. The HV6-BAN4 cable can be used to connect a DMM's banana jack inputs to each multiplexer bank's common terminals for simplified connectivity. This configuration guarantees safe connections while streamlining the procedure.
The NI-SWITCH driver is a piece of IVI-compliant software that facilitates full functionality for all National Instruments PXI switch modules, including the 778572-27. A visual routing environment and intuitive switch administration are two further sophisticated features of the NI Switch Executive software, which is also available for programming, configuring, and maintaining high-channel-count switching systems. To facilitate relay operations and debug switch code execution, the NI-SWITCH soft front panel is also offered.
