Measuring circuit monitoring
The device behavior in the event of a malfunction is configurable.
Designation Measuring range Accuracy

Input resistance or bur-
den voltage
Voltage 0 to 70 mV ≤ 0.1 % > 500 kΩ
0to10V ≤ 0.05 % > 500 kΩ
-10 to +10 V ≤ 0.05 % > 500 kΩ
-1 to +1 V ≤ 0.08 % > 500 kΩ
0to1V ≤ 0.08 % > 500 kΩ
Current 4 to 20 mA ≤ 0.1 % < 2V
0to20mA ≤ 0.1 % < 2V
Ambient temperature influence ≤ 100 ppm/K
Smallest measuring span
Voltage 5 mV
Current 0.5 mA
Measuring range start/end
Voltage Freely programmable within the limits, in increments of 0.01 mV
Current Freely programmable within the limits, in increments of 0.01 mA
Deviation below/above the mea-
sur. range
According to NAMUR recommendation NE 43 (only current input 4 to 20mA)
a
Accuracy refers to the maximum measuring range. Small measuring spans lead to reduced linearization accuracy.
