5pcs New Battery Charging and Discharging Automatic Power-off Modul XY-DJ

Description: Model: XY-DJ Integrated voltmeter undervoltage and overvoltage protection for battery charging and discharging module with timed charging and discharging communication function Attention! If the digital display shows "ERR", it is an error prompt because your setting parameters do not meet the specifications, such as the upper limit value being lower than the lower limit value. Please modify the setting parameters again. Module highlights: 1. Battery charging and discharging control, automatically power-off after setting; 2. The charging and discharging time can be set; 3. With serial communication function, the working status of the relay can be monitored in real time through the serial port; 4. An additional signal output can be used to control other devices when the relay conduction condition is met and a high level is output. 5. It has a one key emergency stop function (STOP key) with reverse connection protection, and reverse connection does not burn; Working mode: Voltage upper limit: UL1, voltage lower limit nL1, voltage upper limit should be greater than voltage lower limit (UL1>nL1) U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay will engage. When it is higher than the upper limit voltage, the relay will disconnect; U-2: Charging measurement time control: Set the charging time (OP); When the measured voltage is lower than the lower limit voltage, the relay will engage. After engaging, the countdown to OP time will begin. When the time is up, the relay will disconnect; If the voltage exceeds the upper limit, the relay will disconnect. U-3: Discharge detection: When the measured voltage is below the lower limit voltage, the relay will disconnect; when it is above the upper limit voltage, the relay will engage; U-4: Discharge detection time control: Set discharge time (OP); When the measured voltage is higher than the upper limit voltage, the relay will engage. After engaging, the countdown to OP time will begin. When the time is up, the relay will disconnect; When the measured voltage is below the lower limit voltage, the relay will disconnect; U-5: Close in the interval: When the measured voltage is between the upper and lower limits, the relay will close and disconnect in other situations; U-6: Out of range pull-in: When the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay will pull in, and in other cases, the relay will disconnect; Product parameters: 1: Power supply voltage: DC6-40V, voltage detection range DC 0-60V, suitable for various batteries below 60V, voltage testing error ± 0.1V. 2: Charging and discharging time (OP) range: 0-999 minutes. How to set parameters Firstly, 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 the current working mode (default U-1 mode), and then enter the main interface), press and hold the SET button for 2 seconds and then release to enter the mode selection interface. Select the mode to be set (U-1~U-6) by short pressing the UP and Down buttons; 3. After selecting the mode to be set (such as U-1), press the SET key briefly to set the corresponding parameters. At this time, the parameters to be set will flash (UL1 voltage upper limit, nL1 voltage lower limit, OP conduction time). Adjust the parameter values through UP and Down, and support long pressing (quick increase or decrease) and short pressing (increase or decrease by 1 unit); Short press the SET key to set the next parameter for the current mode, the process is the same as above; 4. After setting the parameters for the selected mode, press and hold the SET key for 2 seconds before releasing it. The currently set mode will flash and then return to the main interface. The parameter setting is successful, very simple! 5. On the main interface, short press the DOWN button to switch between voltage and time, which is very simple. Mode selection interface: Long press the SET key to enter. After setting is completed, long press the SET key to exit and return to the main interface. It is very simple! 5、 Serial port control (microcontroller TTL level communication) Communication standard: Baud rate 9600 bps Data bit: 8 Stop bit: 1 Check digit: none Flow control: none Serial port instructions: "U-1": Working mode (value range U-1 to U-6) "000": Time parameter 0: Do not enable timing function, non 0: Enable timing function (value range from 000 to 999) "Dw02.9": Set lower limit voltage "Up10.1": Set upper limit voltage (value range: 00.0V~60.0V) "Get": Get the current settings "On": Allow relay to conduct "Off": always turn off the relay "Start": Start uploading data "Stop": Stop uploading data The above commands can be combined with any two, separated by commas For example, "dw02.9, up10.1" sets the lower limit voltage to 02.9V and the upper limit voltage to 10.1V Upload status: Test voltage+conduction time+status "00.0V, 00:00:00, OP \ r \ n" 00.0V: measured voltage 00:00:00: Relay conduction time Status: OP relay conducting, CL relay disconnected
