Description
The National Instruments PXI-2571 PXI Relay Module, with Part Number 778572-71, is a versatile 66-channel relay module designed for high-density switching applications. Each of its channels utilizes SPDT (Form C) relays, providing a variety of terminal types including Normally Closed (NC), Normally Open (NO), and Common (COM) to accommodate different circuit configurations. This module can handle voltages up to 100 VDC/100 VAC and currents up to 1 A, suitable for a wide range of signal levels.
With its capacity to store up to 1024 scan instructions, the PXI-2571 allows for extensive test sequence automation, while the integrated Switch Control Circuitry (SCC) efficiently manages the opening and closing of relays for reliable operation. The module comes with software that simplifies setup by automatically configuring the hardware and downloading the scan list directly into the module’s memory, which streamlines the testing process and enhances performance.
Additionally, the PXI-2571’s capability to interface with measurement devices ensures that signals are correctly routed before measurements begin, and it supports waiting for an external trigger to start scanning, ensuring synchronization with other test instruments in a system. This level of integration and automation makes the National Instruments PXI-2571 an essential component for advanced automated test equipment (ATE) setups.
