Feature: 1. AUTOMATICALLY POWER OFF AFTER SETTING: This module can realize battery charge and discharge control, automatically power off after setting 2. SET CHARGING AND DISCHARGING TIME: The charging and discharging time can be set, power supply voltage is DC6-40V, voltage detection range is DC0-60V, suitable for various batteries below 60V, and the voltage test error is ±0.1V 3. SERIAL PORT COMMUNICATION FUNCTION: With serial port communication function, the working status of the relay can be monitored in real time through the serial port 4. ADDITIONAL SIGNAL OUTPUT: There is an additional signal output, when the relay conduction condition is met, the output is high, and other devices can be controlled 5. ONE KEY EMERGENCY STOP FUNCTION: There is one key emergency stop function (STOP key), with reverse connection protection, reverse connection does not burn Specification: Item Type: Battery Charge Discharge Module Power Supply Voltage: DC6-40V, voltage detection range DC 0-60V, suitable for various batteries below 60V, voltage test error ±0.1V. Charge And Discharge Time (OP) Range: 0-999 minutes. Operating Mode: Voltage Upper Limit: UL1, voltage lower limit nL1, voltage upper limit must 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 is closed, and higher than 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 the OP time starts to count down after the pull in. When the time is up, the relay is disconnected; when the voltage is higher than the upper limit voltage, the relay disconnect. U-3: Discharge Detection: When the measured voltage is lower than the lower limit voltage, the relay is disconnected, and when the measured voltage 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 the OP time starts to count down after the pull in. When the time is up, the relay is disconnected; when the measured voltage is lower than the lower limit Voltage, the relay is off; U-5: Closed In The Interval: When the measured voltage is between the upper limit and the lower limit, the relay is closed, otherwise disconnected; U-6: Pull In Outside The Interval: When the measured voltage is lower than the lower limit voltage or higher than the upper limit voltage, the relay is pulled in, and the relay is disconnected in other cases..
