Item Type: Dual MOS Tube Control Board Material: PCB Wide Voltage: 5-30V Package List 1 x Dual MOS Tube Control Board 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, the current working mode (default P1.1 mode) will flash, and then enter the main interface.) "Press and hold the SET key for 2 seconds and then release it" to enter the mode selection interface, and press the UP and DOWN keys briefly to select the mode to be set (P1.1~P4).3. After selecting the mode to be SET (for example, P3.2), press the SET key briefly to set the corresponding parameters. At this time, the parameters to be set will flash (OP on time, CL off time, LOP cycle number (""stands for infinite cycle)). Adjust the parameter values through UP and DOWN, and support long press (fast increase or decrease) and short press (increase or decrease by 1 unit); After setting the parameter value, press the STOP key briefly to select the decimal point position and the timing range (the corresponding time is 0.1 seconds to 999 minutes); Press the SET key briefly to set the next parameter of the current mode, and the process is the same as above.4. After setting the parameters of the selected mode, press and hold the SET key for 2 seconds and then release it. The currently set mode will blink, and then return to the main interface. Setting the parameters is successful, which is very simple.Main interface: "000" (without decimal point) is displayed when the relay is not working, and decimal point is displayed when the relay is working, which is very clear.Mode selection interface: press and hold the SET key to enter; after setting, press and hold the SET key to exit and return to the main interface. 1Superior Performance: Dual MOS tube control board to achieve high frequency circuit fast and frequent on and off, unlimited switching times; on and off process does not generate noise, no electrical sparks, no electromagnetic interference. 2High Power: Trigger cycle timer delay switch circuit board uses dual MOS parallel active output, lower internal resistance, higher current, strong power, 15A at room temperature, 400W, to meet the use of most equipment. 3Widely Used: Dual MOS tube control board is commonly used to control motors, light bulbs, LED strips, DC motors, micro pumps, solenoid valves, etc. Through this module, you can easily control these devices, very convenient. 4Wide Voltage, Simple Interface: Dual MOS tube control board works with wide voltage (5~30V), most devices can be used, very convenient; the interface is clear and simple, powerful and easy to understand, almost meet all your needs. 5Stop Function, Sleep Mode: Dual MOS tube control board has a key emergency stop function (STOP key), with reverse connection protection, reverse connection does not burn; increased sleep mode, after enabling, no operation within 5 minutes, automatically turn off the display. 6Parameter Settings: Digital time delay relay any key to wake up; can set different OP, CL, LOP parameters, these parameters are independent of each other and saved separately; all set parameters are automatically saved by power down.
