The DNx-DIO-433-800 boards are 32 channel, digital output boards that provide extremely low (< 1 µA) leakage current when outputs are in the OFF state. Each channel is configured as a current source and switches voltages between 3.3 and 36 VDC. Additionally, each channel is rated for continuous operation at 600 mA with an output voltage drop of less than 550 mV.

As part of UEI’s Guardian series, the DNx-DIO-433-800 not only controls the digital outputs, it provides a unique output monitoring capability. An on-board 24-bit A/D converter monitors each channel’s output current. This allows the application to detect and flag short and open circuits as well as other “suspicious” behavior. The monitoring capability is also a powerful diagnostic tool allowing a repair technician to quickly and accurately identify blown, or mis-wired channels.

The DNx-DIO-433-800 is a special, low leakage current version of the DNx-DIO-433. The board is ideally suited for controlling LED indicators that will be viewed through night vision devices.
