Hello Guys,
I wanna measure two AC currents by PLC. I have two Hall effect sensor type: ACS758LCB-050B for this issue .my PLC (analog card: G6F-AD2A LG-Glofa GM6) cannot precess these AC signals (for this matter it must be so fast) and I should have DC signal for this matter.
signal range is : 1v to 5v peak to peak and frequency is 50 Hz.
thanks for your ideas
 

What do you think about this circuit?
