PCI-7833R

Model: PCI‑7833R Brand: NI (National Instruments) Type: Multi-function RIO (AI + AO + DIO) PCI Card FPGA: Xilinx Virtex-II XC2V3000 (3M gates) Bus: 32-bit 5V PCI Connector: 2 × 68-pin VHDCI Driver: LabVIEW FPGA, NI-RIO Status: Mature supply; recommended as an alternative to PCIe‑7842R Core Overview PCI‑7833R is a high-end R-series multi-function RIO board, integrating 8 channels of AI + 8 channels of AO + 96 channels of DIO and 3M gate FPGA. The FPGA resources have been increased by 3 times compared to PCI‑7831R. It is suitable for complex analog + digital mixed real-time systems, HIL simulation, high-speed control, and precise signal generation / acquisition. All I/O is directly controlled by the FPGA hardware, with a timing accuracy of 25 ns. Customized timing, triggering, and on-board decision logic are available.
