Upper and Lower Limit Voltage Comparator Double Limit Voltage adjustable range is 0-32V

Description

Set the upper and lower limit voltage on the module, input the sampling voltage from [3] or [4],

 when the input voltage value is within the set upper and lower limits Within the voltage range, the relay is closed.

 When the input voltage of [3] or [4] is greater than or less than the set upper or lower limit voltage, the relay is turned off.

 Upper and lower limit voltage:

After the upper and lower limit voltage is set, it is not affected by the voltage change of the module power supply [1-2], adjustable range is 0-32V. 

Module use:
