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.

PLATFORM MODULES

Platform modules integrate with modular hardware platforms that allow you to combine different types of modules in a custom system that leverages shared platform features. NI offers three hardware platforms—CompactDAQ, CompactRIO, and PXI—though all platforms may not be represented in this category.
