National Instruments NI PXI-7841R R Series Reconfigurable I/O Module

Condition:Used The National Instruments PXI‑7841R is an R‑Series reconfigurable I/O (RIO) module powered by a user‑programmable Xilinx Virtex‑5 LX30 FPGA, delivering hardware‑level deterministic timing and high‑speed onboard signal processing. It features 8 analog input (AI), 8 analog output (AO), and 96 bidirectional digital I/O (DIO) channels, with a maximum 200 kS/s analog input sampling rate, -10 V to +10 V analog input range, and 3.3 V/5 V digital logic levels. Each analog input channel has an independent ADC, supporting multi‑rate sampling and individual channel triggering, far beyond standard DAQ hardware capabilities. Programmable via the LabVIEW FPGA Module, it is widely used for hardware‑in‑the‑loop simulation, custom protocol communication, high‑speed real‑time control, sensor simulation, and industrial automation testing. Built‑in Flash memory enables automatic FPGA code loading on power‑up for standalone operation.
