1. Input voltage with a reference voltage set on the module (reference voltage can be set through an adjustable potentiometer), when the input voltage is greater than the reference voltage, the relay is closed, the circuit is turned on; when the input voltage is less than the reference voltage, relay off, the circuit is disconnected.

2. To be compared input voltage are signal A and signal B, when the voltage of signal A ?is greater than the voltage signal B, the relay is closed, the circuit is turned on; when the voltage of signal A is less than the voltage signal B, the relay off, the circuit is disconnected .

3. The input voltage value is 12V, then the adjustable reference voltage range is 0-12V.

4. Can be used to car circuit modification, industrial equipment, experimental testing, and circuit testing applications.

5. Working voltage: DC5V, 12V, 24V

6. Typical operating current: DC5V 100mA; DC12V 52mA; DC24V 28mA

7. Standby current (relay engagement portion off): Approximately 5uAAlso, you read this:
