The DNx-DIO-449 is a 48 channel, high performance AC and DC digital input board designed for use in a wide variety of digital monitoring applications. The board's inputs are divided into two 24-bit ports, each of which presents its data in a 24-bit read. This simplifies programming and maximizes throughput. This simplifies programming and maximizes throughput. The board reads all 48 bits at sustained rates in excess of 1 kS/second. Automatic Change Of State (COS) detection is available with 200 μS accuracy.

The board offers programmable logic thresholds and hysteresis over the full input range. Thresholds and hysteresis are independently programmable on each channel. The board supports user programmable debouncing intervals for DC inputs which may be set on each channel independently with durations up to 400 ms. Each board provides 350 Vrms isolation. All inputs are over-voltage protected from -350 to +350 VDC, and against ESD.

The DNx-DIO-449 is equipped with the “Guardian advantage”, a UEI feature that provides powerful diagnostic capabilities. When enabled, Guardian diagnostic circuitry can inject a test signal at the channel input, allowing the full input hardware chain to be tested for proper functionality. In addition, the inputs are based on A/D converters which allows a diagnostic input mode that monitors the actual analog voltage at each input. The board will also monitor switches or contacts without external circuitry. The analog voltage measurement capability also allows a quick and accurate detection of short and open circuits as well marginal or failing drive circuitry. The analog input capability is also a powerful installation and diagnostic tool.
