Home Shop Data Acquisition and Control Digital I/O

Digital I/O

Digital I/O products can acquire and generate digital signals and patterns at multiple logic levels. You can characterize circuits, toggle control lines, and meet many other digital application needs.

digital input and output hardware is available in a variety of form factors, such as usb, pci, pci express, and remote i/p

I/O, Logic Levels, and Form Factors for a Broad Range of Applications

Digital I/O hardware includes options for a wide range of channel counts, voltage logic levels, and form factors, including USB, PCI, PCI Express, and remote I/O. With this variety, you can choose hardware to handle all the signal types you need.

Industrial Digital Output Sensor Compatibility

Digital output sensors and actuators driven by digital signals are popular across several industries. NI digital I/O hardware includes options for different sinking and sourcing outputs, off-state leakage current, minimum holding current, and other key parameters.

Reconfigurable Digital Inputs and Digital Outputs

Reconfigurable digital I/O products offer advanced functionality, such as multirate sampling and individual channel triggering, because of the onboard FPGA. You can customize these models with the LabVIEW FPGA Module.
