I have built a current loop protection circuit based on the topic Using a microcontroller ADC to measure a 4-20mA sensor
It works good. The next step is I want to protect the input of the circuit from the incorrect hookup. Can I use two Schottky diodes? Would this work correct? I want this circuit to be compatible with 0-10V sensors as well. In that case should I consider the voltage drop by the software when using an ADC? Or maybe there is an other solution?
