Hello Gog;
As you can see from the attached illustration (from the S7-300 Module Data manual), you can only connect one RTD per 2 analog channels.
Hope this helps,
Daniel Chartier

Hello George;
With the module you are using (AI 331-7KB02, 2 analog input channels with Resistsance temperature measurement) you can only connect 1 RTD.
If you had for example a AI 331-7KF02, 8 analog input, with Resistance temperature measurement, you could connect 4 RTD max (1 per 2 channels).
Hope this helps,
Daniel Chartier
