Input board with voltage measurement for short & open circuit detection

The DNx-DIO-448 is a highly flexible digital input board with 48 channels, featuring a diagnostic mode that monitors the actual analog voltage at each input for rapid detection of short and open circuits as well as other faults. It is ideal for a wide range of marine digital monitoring applications.

The board offers individually programmable debouncing intervals, logic thresholds and hysteresis over the full input range for each channel. All inputs are overvoltage protected to ±40 VDC, and are also equipped with robust ESD protection.
