Measuring
- Measuring ranges / load resistance0 ... 20 mA / 50 ohms,
- 4 ... 20 mA / 50 ohms,
- ±20 mA / 50 ohms
- Measuring methodIntegration
- Measurement resolution11 bit + sign
- Interference frequency suppressionNone | 10 Hz | 50 Hz | 60 Hz | 400 Hz
- Refresh rate / conversion rateNumber of active channels x conversion time + 16 ms for wire break detection when activated.
- The conversion time will depend on the interference frequency suppression:
- None: 8 ms
- 400 Hz: 45 ms
- 60 Hz: 109 ms
- 50 Hz: 128 ms
- 10 Hz: 342 ms
- DiagnosesUpper measuring range limit exceeded (overflow), lower measuring range limit fallen below (underflow), wire break (for 4 ... 20 mA only), parameter assignment error
- Process alarmsUpper and lower limit per channel
