The size is about 12x7x6cm and the weight is about 150g. There is no built-in battery. If you want to use the pneumatic function of this controller, please bring your own AC12V power supply with a power of more than 12W. If you do not use the pneumatic function, the AC9V power supply sold in this store will do. Dear friends, please pay attention! A generation of color screen pneumatic personalization, NY-D0 point report small controller. Integrated temperature, fan, pneumatic control integrated control, no external power supply high current driver chip, directly drive DC12V solenoid valve, fan no longer needs external power supply. The large-size color screen displays clear display and the interface is generous. Use a large color screen as the display interface to make your machine more advanced. The imported ST STM32 microcontroller has fast computing speed, strong anti-interference and fast running speed, stable enhanced model, and strong anti-interference ability. You can choose bilingual selection of Chinese and English interface, and you can choose Chinese or English to make your machine more advanced. All pneumatic parameters can be changed. Complete pneumatic parameters, more in line with your machine pneumatic continuous welding points 1-10 points change parameters according to the mechanical characteristics of your own machine. Temperature detection fan control, so that your whole machine will not overheat with temperature protection upper limit function fan has normally open, closed, intelligent control mode. Terminal description: 1: Foot switch terminal, connected to the mechanical switch. 2: Control board power supply, connected to AC 9 to 12V power supply, must be AC. 3: Temperature sensor terminal. 4: Status terminal, controller welding status, output during welding. 5: Fan terminal, connected to DC12V fan. 6: Solenoid valve terminal, connected to DC12V pneum
