NI PCI-7813R Digital reconfigurable I/O device

The NI PCI-7813R is a digital reconfigurable I/O device manufactured by National Instruments. This device uses the Real-time System Integration (RTSI) bus, and it belongs to the R series of digital reconfigurable I/O devices. The device has 160 digital lines and can be configured for input, output, timer or custom logic at rates up to 40 MHz. It uses a Virtex-II 3 million gate FPGA and can be programmed with the LabVIEW FPGA module.

The NI PCI-7813R also features user-defined trigger, timing, and on-board decision making at 25 ns resolution, and can be connected to the NI 9151 for analog and digital I/O expansion or signal conditioning. It also has built-in examples for I2C, SPI, S/PDIF, RS232 and other digital communication protocols.

On the usage side, the user can access the channel using an FPGA I/O node configured to read or write, or set output data/set output enable method. RTSI/RTSIx Trigger channel x The x in the channel X represents the channel number, ranging from 0 to 6. At the same time, RTSI/RTSI7 acts as an RTSI oscillator channel and can also act as an additional trigger channel.

PCI-7813R has a wide range of application scenarios, mainly used in power, petroleum, mine lifting, port, heating, gas, water supply, sewage treatment, metallurgy, paper, textile, chemical industry, water conservancy and other modern industrial fields. In these areas, the PCI-7813R can play to the advantages of its digital reconfigurable I/O device, through its high-speed input and output capabilities, powerful data processing capabilities, and flexible custom logic configuration to meet a variety of industrial automation and process control needs.
