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.
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.
Selecting digital I/O hardware for test, control, and design
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.
Choosing the right industrial digital I/O module for your digital output sensor
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.
