Measuring ranges150 Ohm / 300 Ohm / 600 Ohm / 3000 Ohm / 6000 Ohm PT 100 / PT 1000 Ni 100 / Ni 1000 LGNi 1000 PT 100 Klima / PT 1000 Klima
Measuring methodIntegration
Measurement resolution15 bits + 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 for each channel 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, parameter assignment error
Process alarmsUpper and lower limit per channel
