Industry control printed circuit boards (PCB)
1. For industrial control, special or general-purpose circuit board, the bottom circuit is completed, and IO is reserved. After buying the industrial control circuit board, the input and output ports reserved on the circuit board are connected to the user's own device, such as motor, solenoid valves, sensors, thus completing the function want to accomplish.
2. The special circuit board is a board specially designed for a certain function, such as the temperature control circuit board. After buying it, the input port is connected to the thermocouple, and the output port is connected with a heating contactor or a solid state relay to control the heating device to complete the temperature control. There are flow control boards, motion control boards, etc.
3. The universal control board, most of which can be programmed, after the user's own secondary development, completes a specific function, and has a wide range of uses. For example, plc is a general industrial control board. After the user writes the program and compiles the input, various functions can be completed. Digital input, analog input port, high-speed counter port, digital output port, analog output port, and some also have communication function.
