Abb AI835, one rtd for multiple AI835 temp. compensation
Is it possible to use the same pt100 on multiple AI835 analog input cards? If not, is it possible to take temp. compensation from the application using AI835, NOT AI835A, with which i think it is possible.
If none of the above is possible, is it possible to calculate it from the single pt100 inside the application and is it a good solution?
It is not possible to use 1 Pt100 to more than one input or transmitter. That comes from measuring principle for Pt100 sensors.
Using of application value for temp. compensation is possible only for AI835A:
- Fix, the FJT is used as reference temperature -> there is an Output QW, where you can connect your value (described well in module help)
Last question is not clear - what do you want to calculate?
