The AI-DI 16/DQ16Г—24 V DC HART HA analog/digital module has the following technical features:

• 16 inputs configurable as digital or analog inputs
• Digital inputs with the following features configurable per channel:
  • Pulse stretching
  • Time stamping in mixed mode
  • Time stamping with a precision of 1 ms in digital-only mode
  • Hardware interrupts for positive and negative edges
  • Input delay
• Analog inputs with the following features configurable per channel:
  • Current measurement type for 2-wire measuring transducer
  • Measuring ranges 0 to 20 mA, 0 to 10 mA, 4 to 20 mA or 4 to 20 mA with HART
  • Resolution depends on measuring range and interference frequency suppression; minimum of 15 bits, maximum of 16 bits including sign
  • Hardware interrupts for monitoring configurable limits
