Description
The National Instruments PXIe-7821 PXI Digital Reconfigurable I/O Module is a versatile and high-performance module equipped with 512 MB DRAM for efficient processing and features 128 DIO channels for comprehensive digital interfacing. It utilizes the powerful Kintex 7 160T FPGA for advanced digital signal processing and is available under part numbers PXIe-7821R and 783485-01. This module is classified for measurement applications on specially insulated secondary circuits, which are not directly connected to the hazardous MAINS voltage.
Designed for compatibility with PXI Express, PXI Express hybrid peripheral slots, and synchronization slots of the PXI Express framework, it ensures a wide range of deployment options within the modular instrumentation platform. Users are advised to limit long-term over/under voltage exposure to safeguard the module’s lifespan. The inclusion of an external clock input facilitates synchronous operations, enhancing measurement accuracy and system integration.
Upon power on, the DIO channels default to low input states with pull-down resistors to ensure system stability. Moreover, for custom applications, the module allows users to configure a power state at power-on by loading a VI that can set the DIO lines to any power state, providing flexibility in system startup behavior.
