Measuring

• Measuring ranges / load resistance
  • 0 ... 20 mA / 50 ohms,
  • 4 ... 20 mA / 50 ohms,
  • ±20 mA / 50 ohms
• Measuring method Integration
• Measurement resolution 15 bits + sign
• Interference frequency suppression None | 10 Hz | 50 Hz | 60 Hz | 400 Hz
• Refresh rate / conversion rateThe conversion time will depend on the interference frequency suppression:
  • None: 2.5 ms,
  • 400 Hz: 8 ms,
  • 60 Hz: 51 ms,
  • 50 Hz: 60 ms,
  • 10 Hz: 160 ms
• Diagnoses Upper measuring range limit exceeded (overflow), lower measuring range limit fallen below (underflow), wire break (for 4 ... 20 mA only), parameter assignment error
• Process alarms Upper and lower limit per channel
