DNx-DIO-433-800 – Guardian series Digital Output Interface

Guardian series 32 channel, 600 mA, current sourcing digital output interface with output voltage and current monitoring


The DNx-DIO-433-800 are 32 channel, digital output boards designed for use in a wide variety of applications. Based on the popular DNx-DIO-433, the 433-800 provides lower leakage outputs, which is critical in simulator applications where LED indicators are viewed through night vision devices.



  • 32 digital outputs
  • 600 mA (current source) outputs
  • Wide 3.3 to 36 VDC output range
  • 1 kHz maximum update rate
  • Low leakage outputs suitable for controlling LED indicators viewed by night vision devices

Guardian Series Diagnostics

  • Programmable overcurrent protection (50 mA to 1 A)
  • Programmable overcurrent duration limits
  • PWM based soft-start/stop reduces inrush current “shock”
  • Monitors each channel’s output current allowing automatic detection of shorts/open and other system failures

As part of UEI’s Guardian series the board not only controls the digital outputs, it provides programmable overcurrent protection as well as a unique monitoring capability.

This monitoring capability is a powerful diagnostic tool allowing a repair technician to quickly and accurately identify blown, or mis-wired channels.

The DNA-DIO-433-800 is fully supported by the UEIDAQ Framework which provides a simple and complete software interface to all popular programming languages, operating systems and data acquisition and control applications (e.g. LabVIEW, DASYLab, MATLAB).
