Between the channels No
Current draw
ExternalNot needed
Internal Max. 95 mA
Power dissipationMax. 0.7 W
Measuring ranges / load resistance0 ... 20 mA / 50 ohms, 4 ... 20 mA / 50 ohms, ±20 mA / 50 ohms
Measuring methodIntegration
Measurement resolution12 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 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
Error limits
