DVB01 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, , 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 needs
2.The user can set the voltage upper limit and voltage lower limit
3. Measuring range 0-100V, measuring accuracy + 0.1V
5. Increase the pull in delay and disconnect delay function
6. All settings parameters can be automatically saved, the content of power loss is not lost
7. 0-99.9 seconds delay pull-IN and 0-99.9 seconds delay the pull-off function

Module 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.
