hi doc
the LT in my diagram is the transducer im using LTSR-25, its output is 2.5v to 4.5v.
im asuming 2.5v at min current 0.001a and 4.5 at max current 25amps. thats the range of the transducer.
yes sorry i should have said , the input is in my sketch has internal pull up resistor, when a low is present an i get an output to an alarm.
thank you
