Representation of the analog values of Ni x00 climate resistance thermometers
The following table shows the analog values for the resistance thermometer Nix00 Climatic
for all analog input modules.
Exceptions:
● Analog input module AI 8x12-bit; 6ES7331-7KF02-0AB0
● Analog input module AI 2x12-bit; 6ES7331-7KB02-0AB0
There is no overrange for these analog input modules. Overflow begins at 240 °C and is
