Features 1、Battery charge and discharge control, automatically set off after setting. 2、Can set the charge and discharge time accurately recording to your needs. 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, when the relay conduction condition is met, the output level is high, and other devices can be controlled. 5、One button emergency stop function (STOP button), with reverse connection protection, reverse connection does not burn. Specification Features: Battery charge and discharge control, automatically set off after setting. Can set the charge and discharge time accurately recording to your needs. With serial communication function, the working status of the relay can be monitored in real time through the serial port. An additional signal output, when the relay conduction condition is met, the output level is high, and other devices can be controlled. One button emergency stop function (STOP button), with reverse connection protection, reverse connection does not burn. Specification: Suitable for :Battery below 60V Charging and Discharging Time Setting:0~999m Serial Port Control(SCM TTL level communication): Communication Standard: Baud Rate 115200 Bps Data Bit : 8 Stop Bit :1 Check Digit :None Flow Control : None Size:6.4 x 4cm / 2.52 x 1.57in Package List: 1 x Charge Discharge Protection Board Users Manual: 1. First determine the operating 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), then enter the main interface), long press the SET button for 2 seconds and then release , enter the mode selection interface, select the mode to be set (U-1~U-6) by short pressing the UP and DOWN buttons; 4. After setting the parameters of the selected mode, press and hold the SET button for 2 seconds to release, the currently set mode will flash, then return to the main interface, setting the parameters successfully, very simple! Mode selection interface: long press SET button to enter, after setting is completed, long press SET button to exit, return to the main interface, very simple! Serial Command: /"U-1/": working mode (value range U-1 ~ U-6) ''000'': Time parameter 0: Do not enable timing function Non-0: Enable timing function (value range 000~999) /"get/": Get 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 in any two, and need to be separated by commas. "00.0V, 00:00:00, OP//r//n" 00:00:00 : Relay conduction time Status: OP relay is on CL relay is off Relay Using Mode: 1. ON: The relay is allowed to conduct during the OP conduction time; 2. OFF: The relay is prohibited from being turned on and is always off. Short press the STOP button on the main interface to switch between ON and OFF. The current state will flash and then return to the main interface. (This function is the emergency stop function, one button to open and close the relay) Sleeping Mode: 1. C-P sleep mode: within five minutes, without any operation, the digital tube automatically turns off the display and the program runs normally; 2. O-d normal mode: the digital tube is always on display; Press and hold the STOP button for 2 seconds and then release it to switch between C-P and O-d. The current state will flash and return to the main interface. Package List
