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.
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.
