Product Description:Module Highlights:Intelligent control of battery charge and discharge; charge and discharge time can be set;With serial port communication function, the working status of the relay can be monitored in real time through the serial port;Additional signal output, when the relay meets the conditions, it outputs high level and can control other devices.-button emer gency stop function (STOP button), with reverse connection protection, it will not be burned when reverse connection is made.Operating mode:Voltage upper limit: UL1, voltage lower limit nL1, voltage upper limit is greater than voltage lower limit (UL1>nL1)U-1: Charging measurement: When the measured voltage is lower than the lower limit voltage, the relay is closed; above the upper limit voltage, the relay is disconnected.U-2: Charging measurement time control: set the charging time (OP); when the measured voltage is lower than the lower limit voltage, the relay is closed, and then starts counting down the OP time, the timer ends, and the relay is turned off; when the measured voltage is higher than the upper limit voltage , the relay is disconnected.U-3: Discharge detection: When the measured voltage is lower than the lower limit voltage, the relay is disconnected, and when it is higher than the upper limit voltage, the relay is closed;U-4: Discharge detection time control: set the discharge time (OP); when the measured voltage is higher than the upper limit voltage, the relay is closed, and then starts counting down the OP time, the timer ends, and the relay is turned off; when the measured voltage is lower than the lower limit When the voltage is high, the relay is disconnected;U-5: The voltage is within the range and the relay is closed: When the measured voltage is between the upper and lower limits, the relay is closed and open in other cases;U-6: The voltage exceeds the range, the relay is closed: the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay is closed, otherwise the relay is disconnected.Product parameters:1: Power supply voltage: DC 6--40V, voltage detection range DC 0--60V, suitable for various batteries below 60V, voltage measurement error ±0.1V.2: Charge and discharge time (OP) range: 0-999 minutes.How to set parameters?First, determine the requirements for the working mode according to your own needs;According to the working mode of the relay, on the main interface (the current working mode will flash when the module is powered on, the default is U-1 mode, and then enter the main interface) press the SET key for 2 seconds and release it to enter the selection mode interface, press UP, DOWN key to select the mode to be set (U-1~U-6);After selecting the mode, assuming we selected the U-1 mode, press the SET button to set the corresponding parameters. The parameters that need to be set will flash (UL1 voltage upper limit, nL1 voltage lower limit, OP conduction time). Press the UP and DOWN keys to increase or decrease. You can press this key to increase or decrease quickly at any time. Press the SET key to set the next parameter. In the current mode, the process is the same as above;Set the parameters, then press and hold the SET button for 2 seconds and release. The current setting mode will flash, and then return to the main interface. The parameter setting is successful!Press the DOWN key in the main interface to switch between voltage and time.Mode selection interface:Press and hold the SET button to enter the mode selection interface. After setting is completed, press and hold the SET button and release it to exit the mode selection interface and return to the main interface.Additional features:Data upload: Data upload is implemented through the serial port, and the voltage and running time are uploaded every 1 second to facilitate later data analysis;Serial port setting parameters: You can set the mode and parameters through the serial port, which is more convenient;An additional signal output, when the relay meets the conditions, outputs high level and the other outputs low level.Serial port control (TTL level communication)Communication standards:Baud rate 115200bpsData bits: 8Stop bit: 1Check digit: nFl ow control: n Serial port com mand:"U-1": operating mode (range U-1 to U-6)"000": 0 - disable timing function, non-0 - enable timing function (range 001 to 999)"Dw02.9": Set the lower limit voltage"Up10.1": Set the upper limit voltage (range 00.0V~99.9V)"Get": Get the current settings"On": Allow the relay to open"Off": Always close the relay"Start": Start uploading data"Stop": Stop uploading dataThe above can be a combination of any two, and they need to be separated by commas.For example: "dw02.9, up10.1" sets the lower limit voltage to 02.9V and the upper limit voltage to 10.1VUpload status: test voltage + connection time + status"00.0V, 00:00:00, OP\r\n"00.0V: Measurement voltage00:00:00: On-time relayStatus: OP relay is on, CL relay is offSTOP key function expansion:Relay enable mode:ON: OP conduction time, the relay is allowed to conduct;OFF: relay disabled, normally closed;Press the STOP button on the main interface to switch between ON and OFF, the current status will flash, and then return to the main interface. (This function is an emer gency stop function, button to disconnect the relay)Sleep mode:C-P sleep mode: If there is no operation within five minutes, the digital tube will automatically turn off the display and the program will run normally;O-d normal mode: the digital tube is always on for display;Press and hold the STOP button for 2 seconds and release it to switch between C-P and O-d states. The current state will flash and then return to the main interface.Package Included:1 x battery charger discharge board undervoltage and overvoltage protection module
