Dual comparator by Cell Factory Sounds
A dual LM324 comparator. Non-inverting input I is normalled to non-inverting input II. The inverting inputs are normalled to 10V and go through attenuators. The comparators only work in positive voltages (so output is 0V when the non-inverting input is below the inverting input), but the module is +/- 12V safe.
