The problem is that I can't isolate the meter (PT100) from the power cables because this meter needs to be powered by the same cables as the analog output of the PT100. Concretely, I must supply the PT100 with 24V and the PT100 gives me the current in the same circuit. So, the power supply is in serie (is it correct in Engish ?) with the analog output. I send in attachment the manual with the wiring (page 38).Sorry, this is in French. Maybe this kind of wiring doesn't fit with the Siemens system...
