I have 3 led indication(Low, Medium, High) which glows based on the level of the tank (Main assembly) and current output of 4 to 20mA and 1-5V DC. I also want to indicate the LED which is 10 meters away from the main assembly. I don't want to use lots of wires from the main assembly. Is it good to use a voltage output where I can use comparator circuit and leds will glow based on the input voltage. But losses will occur with the voltage output. To reduce this losses, can i use current output of 4 to 20mA and in the remote assembly, convert the current to voltage converter and 3 comparator circuit with pre-setted values. Is this method is suitable or any other simple circuit? Pls clarify
