48-Channel AC/DC Digital Input Board
The DNx-DIO-449 is a highly flexible AC and DC digital input board with 48 channels divided into two 24-bit ports, and is ideal for a wide range of marine digital monitoring applications. It features 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. This mode can also inject a signal at the channel input, allowing the full input hardware chain to be tested for functionality.
The board offers individually programmable debouncing intervals, logic thresholds and hysteresis over the full input range for each channel. All inputs are overvoltage protected from -350 to +350 VDC, and are also equipped with robust ESD protection.
