National Instruments PXIe-7821 PXI Digital Reconfigurable I/O Module
The 512 MB, 128 DIO DRAM, FPGA Kintex 7 160T, PXIe-7821 (Part Numbers: PXIe-7821R and 783485-01) is a PXI Digital Reconfigurable I/O Module. The measurement class for this RIO module is for estimations performed on circuits that are not straightforwardly associated with the electrical circulation framework called MAINS voltage. MAINS is an unsafe living energy supply framework that powers the hardware. This class is for voltage estimations of specially protected secondary circuits. These voltage estimations incorporate signal levels, unique hardware, parts of limited energy equipment, circuits fed by directed low voltage sources, and electronic components.
The NI PXIe-7821 module can be put in PXI Express , PXI Express hybrid peripheral slots, or synchronization slots of the PXI Express framework. It is recommended to limit long-term over/under voltage exposure to digital I/O. Dragged in DC voltages that violate the maximum and minimum digital input voltage evaluations can decrease the life of the gadget. Pressures above/beneath the voltage are viewed as prolonged if the gathered time in the irregular condition surpasses 1 year. This model comes with an external clock input source that can be utilized for synchronous source acquisitions. The clock source given must be steady and without issues. When the framework is on, the DIO channels are arranged as a low contribution with pull-down resistors. To set another power state, the user can design the NI PXIe 7821 to load a VI when the framework is on. The VI can arrange the DIO lines in any power state.
