DC 12V 2-Channel Voltage Comparator Precise LM393 Comparator Module

DC 12V 2-Channel Voltage Comparator Precise LM393 Comparator Module

The module name: 2 voltage comparison module
Features: through the comparison of the two voltage to the control circuit on or off by
Function description:
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 (11-10 closed, 11-12 disconnected), when the input voltage is less than the reference voltage, relay does not operate.
Function two: two to compare respectively input voltage signals A and B, when the voltage signal A is greater than the voltage signal B, the relay is closed (11-10 closed, 11-12 disconnected), when the voltage signal A is less than B voltage signal, 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 (11-10 closed, 11-12 disconnected), when the input voltage is greater than the reference voltage, after the electric appliance does not work.
The reference voltage: voltage reference module (1 or 2-3 input voltage value) after precision resistor divider, input voltage value determines the range of the reference voltage value, such as the input voltage is 12V, then the reference voltage adjustable range is 0-12V.
Module purpose: the automobile circuit hardware, industrial equipment, laboratory testing, application testing circuit
Working voltage: DC DC5V, 12V, 24V
Working current: 100mA
