Description
The National Instruments PXIe-7858R, also known as part number 784147-01, is a PXI Multifunction Reconfigurable I/O Module equipped with a powerful Kintex-7 325T FPGA and 512 MB DRAM for advanced applications. It includes 8 analog I/O channels and 48 digital I/O channels, capable of sampling at a rate of 1 MS/s. The module supports various input modes such as DIFF, NRSE, and RSE, which are software-selectable, and offers a versatile input signal range from ±1 V to ±10 V.
It is designed with an input bias and offset current of ±5 nA and provides substantial overvoltage protection for analog inputs with limits of ±42 V maximum when powered on and ±35 V maximum when powered off. The analog output range of the module is ±10 V, with DC output coupling and robust protection against short circuits to the ground.
