Hi,
I have a circuit which reads 24V, scales down to controller compatible voltage and controller reads HIGH when 24V is connected, else 0 when 0V is connected. Essentially its a positive logic. 24V = HIGH and 0V = LOW. If I want to convert the same circuit to a NEGATIVE LOGIC i.e 24V = LOW and 0V = HIGH, what would be simplest way without changing much of hardware circuitry.
I have attached the part of the circuit. Basically I want a inverted LOGIC at output of pin 7 of the opamp.
Regards
