PXI Digital I/O Modules PXI Digital I/O Modules


Pickering's PXI Digital I/O Modules are suitable for operating external devices or for interfacing with external logic. Two choices of output drivers are available:

  • TTL for interacting with external logic
  • Output channels for operating external devices with voltages to 60VDC and current to 2A

Our Digital I/O modules are available with programmable input thresholds – this allows the user to set the voltage of the high and low states of incoming signals. They also have output channels that can be used as high-side drivers for sourcing current or low-side drivers for sinking current.

Take a look at our knowledgebase for a comparison of our digital I/O modules suited for switching large external loads such as relays.

3-year standard warranty

We also offer mating cables and connectors for these modules to ensure speedy and successful system integration. We stand behind our products with a three-year warranty.
