DC6-40V Integrated Voltmeter Undervoltage/Overvoltage Protection Switch Relay Module LED Digital Display for Industrial Supplies
Features:
1. Battery Charging and Discharging Control: Integrated voltmeter Automatically shuts off power after setting, providing control and safety.
2. Adjustable Charging and Discharging Time: Switch relay module allows users to set specific time intervals for charging and discharging.
3. Serial Communication Function: Switch relay module enables realtime monitoring of relay status through serial communication.
4. Additional Signal Output: Battery charge/discharge module provides an extra signal output that controls other devices when the relay is activated.
5. Emergency Stop Function: There is one key emergency stop function (STOP key), with reverse connection protection, reverse connection does not burn; working mode: upper voltage limit: UL1, lower voltage limit nL1, the upper voltage limit should be greater than the lower voltage limit (UL1>nL1).U1: Charge Measurement: when the measured voltage is lower than the lower voltage limit, the relay is absorbed; higher than the upper voltage limit, the relay is disconnected; U2: Charge Measurement Time Control: set the charging time ( OP); when the measured voltage is lower than the lower limit voltage, the relay is absorbed and starts counting down the OP time after absorption, when the time is up, the relay is disconnected; higher than the upper limit voltage, the relay is disconnected; U3: Discharge Detection: when the measured voltage is lower than the lower limit voltage, the relay is disconnected, higher than the upper limit voltage, the relay is absorbed; U4: Discharge Detection Time Control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay will be absorbed, after absorbed, it will start counting down the OP time, when the time is up, the relay will be disconnected; when the measured voltage is lower than the lower limit voltage, the relay will be disconnected; U intrazone absorption: when the measured voltage is between upper limit voltage and lower limit voltage, the relay will be absorbed and disconnected in other cases; U6: Outofzone absorption: the relay will be absorbed when the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage and disconnected in other cases. U6: Outofrange engagement: the relay is engaged when the measured voltage is below the lower or above the upper limit, otherwise it is disengaged.

How to set the parameters
1. First determine the working mode of the relay;
2. according to the working mode of the relay, in the main interface (when the module is powered on, it will flash down the current working mode (default U-1 mode), then enter the main interface,) "long press the SET key for 2 seconds and then release it" to enter the mode selecting interface, and select the mode to be set (U-1~U-6) by short pressing the UP and DOWN keys. -6);
3. After selecting the mode to be set (e.g. U-1), short press the SET key to set the corresponding parameter, at this time the parameter to be set will flash (UL1 voltage upper limit, nL1 voltage lower limit, OP on-time), adjust the parameter value through UP and DOWN, support long press (rapid increase or decrease) and short press (increase or decrease by 1 unit); short press the SET key to set the next parameter of the current mode, the process is the same as above; short press the SET key to set the next parameter of the current mode, the process is the same as above. The process is the same as above. 4;
4. After setting the parameters of the selected mode, long press the SET key for 2 seconds and then release it, the currently set mode will blink, and then return to the main interface, the parameters are set successfully, it's very simple!
5. In the main interface, short press DOWN button to switch voltage and time, very simple.
Mode selection interface: long press the SET button to enter, set the completion, long press the SET button to exit, back to the main interface, very simple!

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
