KNACRO Enhanced version 1-Channel 5V Voltage Comparator Module LM393 Voltage Comparator IC For Automotive circuit modification Industrial equipment Circuit Application Testing

Module Name: Enhanced version Voltage Comparison Module Features: Control the connection and shutdown of the circuit by comparing two voltages Features: The reference voltage independent circuit is added. The reference voltage of the module is not changed by the input voltage after the reference voltage is set. The adjustable range of the reference voltage is: 0-31V. Operating voltage: DC 5V Typical operating current (relay pull state): DC 5V 60mA; Standby current (relay closed): about 5uA; Module uses: automotive circuit modification, industrial equipment, experimental testing, circuit application testing. Function description (2 functions): Function 1: Input a voltage and set the reference voltage on the module (the reference voltage can be set through the adjustable potentiometer) contrast; When the input voltage is greater than the reference voltage, the relay is closed, the circuit connected; When the input voltage is less than the reference voltage, the relay is disconnected and the circuit is disconnected. Function 2: Input a voltage and set the reference voltage on the module (the reference voltage can be set through the adjustable potentiometer) contrast; When the input voltage is less than the reference voltage, the relay is closed, the circuit connected; When the input voltage is greater than the reference voltage, the relay is disconnected and the circuit is disconnected. Reference voltage:0-31V The reference voltage of the module is the input voltage after multi-turn precision potentiometer partial pressure obtained, the input voltage value determines the range of reference voltage value. For example, the input voltage is 12V, then the reference voltage adjustable range is 0-12V. If you have any question , please feel free to contact us.
