platano el boalo Posts: 12 Rating: (0)	good morning, I'm doing a project to measure amps. the ammeter works from 0-100A and the output is 0-10v. the problem I have is that the logo input does not read me a fixed value while the ammeter output is fixed why can it be? Thanks in advance

The power supply of the current converter with the same 24 VDC as the LOGO! supply. Connect the +10 VDC output of the converter to I7. Connect the 0 VDC output of the converter with 0 VDC of the power supply.

I only have a 24v Siemens source, it has two outputs + and - I'll try to unify the -
