Function: the setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast, when the input voltage is greater than the reference voltage, the relay is closed, when the input voltage is less than the reference voltage, relay.
Function two: two input voltage signal respectively to compare 10 and 12, when the voltage signal is greater than the 12 voltage signal 10, the relay is closed, when the voltage signal is 12 less than the voltage signal 10, relay.
Three features: the setting voltage reference input of a voltage and on the module (reference voltage can be set through the adjustable resistor) the contrast, when the input voltage is less than the reference voltage, the relay is closed (6-5 closed, 7-6 disconnected); when the input voltage is less than the reference voltage, relay. (a contrary to function)
Reference voltage input voltage through precision resistor divider to obtain the reference voltage module, input voltage value determines the range of the reference voltage value, included in the input voltage is 12V, then the reference voltage adjustable range is 0-12V
Module purpose: automobile current modification circuit, industrial equipment, laboratory testing, application testing circuit.
Working current: 350mA
