PCI1420PDVG4 Application Field and Working Principle

PCI1420PDVG4 is a digital input/output board developed by National Instruments. It is a PCI bus board with digital data acquisition capabilities. It supports up to 78 channels of digital input and output at 10 Mbps with up to 24.5 mA sourcing and sinking digital I/O channels. This board is part of the National Instruments line of digital data acquisition boards, which are designed for use in industrial, laboratory, and general-purpose applications.

Digital I/O Specifications

The PCI1420PDVG4 board provides 8 digital I/O lines with up to 24.5 mA of sourcing and sinking current per channel. It has a total of 78 channels available on the board and is designed to operate at 10 Mbps. The board can be programmed to monitor the state of the digital inputs or allow the user to directly control the state of the digital outputs.

Input/Output Modes

The PCI1420PDVG4 board supports several different input and output modes. These include Input and Output, Bidirectional, Open-collector Output, and Output High-Z/Pull-down. The board also supports change-of-state digital input detection, and a status port detection system is available on the board.

Software Support

The PCI1420PDVG4 board is supported by National Instruments\' Measurement Studio software. Measurement Studio is a comprehensive set of software tools for developing measurement applications, including data acquisition, signal processing, automation, instrument control and analysis. In addition, this board is compatible with many third-party software packages, such as LabVIEW and MATLAB.

Application Field

The PCI1420PDVG4 board is well suited for use in industrial, laboratory, and general-purpose applications that require high-speed digital I/O. With its combination of features and performance, the board is an ideal choice for applications such as data acquisition, sequencing and control, process monitoring, and communication monitoring.

Working Principle

The PCI1420PDVG4 board works by monitoring the digital inputs and sending the data to an output pin. If the input signals change, the board will generate an interrupt signal which will be sent to a designated output pin. This can be used to signal a state change or be used to trigger an event. The digital output pins can be used to control external devices such as valves, lights, or other actuators.
