  • Function 1: Input voltage and setting voltage between the comparison, the Input voltage is greater than the setting voltage, the circuit is turned on, while the corresponding channel work indicator light; Function 2: Input voltage and setting voltage between the comparison The input voltage is less than the set voltage , the circuit is turned on, while the corresponding channel work indicator light;
  • Input a voltage compared with the reference voltage (reference voltage through precision multi-turn potentiometer partial pressure get), the input voltage is less than the reference voltage, the relay pulls, the circuit is connected, at the same time the work of the corresponding channel indicator light.
  • Input a voltage compared with the reference voltage (reference voltage through precision multi-turn potentiometer partial pressure get),the input voltage is greater than the reference voltage, the relay pull, the circuit connected, at the same time the work of the corresponding channel indicator light.
  • Channel difference is small, more accurate, 0.1V resolution accuracy. There are three versions of 5V / 12V / 24V optional.
  • Module uses: automotive circuit modification, industrial equipment, experimental testing, circuit application testing.
