Features:
The contrast between the voltage on the module and the set voltage reference input (the reference voltage can be set by an adjustable resistor), when the input voltage is greater than the reference voltage, the relay is closed (11-10 closed, 11-12 open), when the input voltage is lower than the reference voltage, the relay will not act.
In order to compare the input voltage signals A and B respectively, when the voltage signal is greater than the voltage signal B, the relay is closed (11-10 closed, 11-12 open), when the voltage signal A is less than the B phase voltage signal relay.
In the module (the voltage of the reference voltage and the set voltage reference input can be set through an adjustable resistance), when the input voltage is lower than the reference voltage, the relay is closed (11-10 closed, 11-12 open), when the input voltage ratio is greater than the reference voltage, the electrical appliance cannot work normally.
Specifications:
Working voltage: DC5V
Working current: DC5V 100mA
The purpose of the module: automotive circuit hardware, industrial equipment, laboratory testing, application test circuits.
Size: 6.33.81cm
Reference voltage:
After a precision resistor divider, input the reference voltage module (1 or 2-3 input voltage value).
The range of the reference voltage value determined by the voltage value, if the input voltage is 12V, then the adjustable range of the reference voltage is 0-12V.
Packing list:
Voltage Comparator * 1
