The comparator IC chip inputs will operate between the voltage range or 0 to 9.5V. The circuit does not have any positive feedback. If one has a very slow moving input with any noise on it the relay may chatter as it passes through the trip point. The circuit board does not have on it any accurate voltage reference. In one mode it uses the 12v supply as reference. One can make one by connecting a wire ended 3 terminal voltage reference to the screw terminals. Board has a supply input reverse protection diode. Inputs have no protection overvoltage diodes to ground or supply rails. For the price good value.
