PCI-7813R

Model: PCI‑7813R Brand: NI (National Instruments) Type: 160-channel FPGA reconfigurable digital I/O (RIO) PCI card FPGA: Xilinx Virtex-II XC2V3000 (3M gates) Bus: 32-bit 5V PCI Connector: 4 × 68-pin VHDCI Driver: LabVIEW FPGA, NI-RIO Status: Mature supply; recommended as a replacement for PCIe‑7842R Core Overview PCI‑7813R is a high-end digital RIO board in the R series, equipped with 3M gate Virtex-II FPGA. It has more logical resources than PCI‑7811R and is more suitable for complex hard real-time logic and large-scale parallel I/O. 160 bidirectional DIO can be independently configured as input/output/counter/encoder/PWM/custom protocol. The hardware timing accuracy is 25 ns, suitable for high-speed waveform generation, HIL simulation, precise timing control, industrial high-speed I/O, etc.
