Hello every body
I have old machine using some of very old proportional valves.....
one of these valves control card is damaged and no one can repaire
I want to use the machine PLC "S7-300" to control the valve instead of the card....
where the valve max current 800mA and AO can deliver 4-20mA
could anybody suggest any kind of amplifier or idea?
