1Provide 5 functions for users to choose, to meet more application needs 2The user can set the voltage upper limit and voltage lower limit 3Measuring range DC 0-100V, measuring accuracy + 0.1V 4Increase the pull in delay and disconnect delay function 5All settings parameters can be automatically saved, the content of power loss is not lostDVB01 module is a multi-function voltage monitoring controller, using industrial-grade micro-controller as the main control unit, measuring a wide range of high precision. The controller prefers 5 different functions, and can customize and add other specific functions according to user's requirements. The user can set the voltage upper limit and the voltage lower limit. The module is made of genuine high-quality components carefully processed, stable performance, can be widely used in a variety of voltage measurement and control applications.Features:1. Provide 5 functions for users to choose, to meet more application needs2.The user can set the voltage upper limit and voltage lower limit3. Measuring range DC 0-100V, measuring accuracy + 0.1V5. Increase the pull in delay and disconnect delay function6. All settings parameters can be automatically saved, the content of power loss is not lost7.New 0-99.9 seconds delay pull-IN and 0-99.9 seconds delay the pull-off functionModule function:Function 1:Voltage measurement: select this function, the relay will not act, digital display current measuring voltage;Function 2:Charging monitoring: when the measurement voltage is lower than the lower limit voltage, the relay is pulled in, higher than the upper limit voltage, the relay is disconnected;Function 3:Discharge monitoring: when the measurement voltage is higher than the upper limit voltage, the relay is pulled in, lower than the lower limit voltage, the relay is disconnected;Function 4:Pull in interval: when the measuring voltage is between the upper limit and the lower limit, the relay is pulled in, and other conditions are disconnected;Function 5:Out of range pull in: when the measurement voltage is lower than the lower limit voltage, or the measurement voltage is higher than the upper limit voltage, the relay is pulled in; otherwise, the relay is disconnected.Warm hint: the controller will automatically judge which is the upper limit voltage and which is the lower limit voltage of the preset voltage V1 and V2 according to different functionsSpecification:Color: Red Material: plastic Operating voltage: DC12V/24V(optional)(should not exceed the nominal voltage of +/- 10%) Operating current:
