July 25, 2017 Rich Nass

Acces I/O Products has a new family of mini PCI Express (mPCIe) digital I/O cards, the mPCIe-DIO family, that feature a large selection of digital I/O functions for compact control and monitoring applications. These small, low-priced, cards offer up to 24 channels with various voltage, isolation, speed, and counter/timer options. They let designers easily integrate additional I/O functions in systems without board modifications or customization.

Dubbed the Digital Integration (DIO) line, the cards encompass a wide variety of digital I/O types, including:

  • 24 channels of 3.3-V LVTTL high-current digital I/O
  • 4, 8, or 16-channel optically-isolated inputs at up to 31-VDC or Vac RMS
  • 4 or 8-channel solid state (FET) or electromechanical relays
  • 4 or 8-channel 32-bit counters supporting both pulse and quadrature signals

All the cards share features, such as memory mapped registers for low-latency operation. Available accessories include cable kits and screw-terminal breakout adapter boards for quick and easy connectivity.

A complete driver support package is provided including a Windows sample program for testing your DIO devices. This simplifies the verification of proper operation. The cards install in most popular OSs, including DOS, Linux, Windows, VxWorks 7, and Windows Embedded Standard. Prices start at $94.
