The DNx-DIO-448 (Guardian series) is a 48-channel, high performance digital input boards designed for use in a wide variety of digital monitoring applications.

The "Guardian advantage" on the DNx-DIO-448 is an innovative A/D input approach allowing the board to offer incredible input flexibility. A diagnostic input mode monitors the actual analog voltage at each input, allowing 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, diagnostic and data acquisition tool.

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 which may also be set on each channel independently.

The DNx-DIO-448 reads all 48 bits at sustained rates in excess of 1 kS/second. Each channel is configured with a 33 kOhm pull up/down resistor. This makes the board an ideal solution for monitoring contact closures as well as standard voltage inputs. The pull-up/pull-down resistors are configured by connecting the “PLEVEL" pins on the I/O connector to Vcc or ground. Each board provides 350 Vrms isolation. All inputs are overvoltage protected to ±40 VDC, and against ESD.
