Description:

The DNx-DIO-448 boards are 48-bit, high performance digital input boards designed for use in a wide variety of digital monitoring applications. The DNR-DIO-448 is for use in UEI's popular "Cube" while the DNR-DIO is designed for use in the new RACKtangle I/O chassis.

The "Guardian Advantage" on the DNR-DIO-448 is an innovative A/D input approach providing incredible input flexibility. A diagnostic input mode measures the actual analog voltage at each input. This allows quick and accurate detection of short and open circuits as well as marginal or failing drive circuitry. The analog input capability is also a powerful installation, diagnostic and data acquisition tool. Finally, the analog input configuration allows the user to select the hi and low transition voltages and Hysteresis.

Features:

• 48 Digital inputs (up to 28 VDC)
• Sample up to 1 kHz
• 350 Vrms isolation
• Monitors contact closures without external components
• Guardian Series Diagnostics
  • A/D input configuration measures actual input voltage and allows detection of short and open circuits.
  • Fully programmable input transition voltages
  • Programmable hysteresis
