In the actual work encountered in the need for isolation control, and voltage conversion, will use this module.Can realize 3.3V or 5V control 3.6--24V voltage level interface, realize the control side conducts, the controlled side also conducts.Optical isolation anti-interference capability. The back can drive high-power transistors, MOS tubes and other occasions that require high voltage drive, but also can directly drive the small power 24V relay work.If it is a pulse signal, please note that the limit of 817 is below 4KHZ, please do not use this module for control signals larger than 4KHZ, it will not work properly.Module parameters:1、Signal voltage at drive end: 3.6-24V2, the output voltage range: 3.6-30V (output current depending on the specific circumstances, but do not 10MA, the total power must be Voltage and current is inversely proportional to)3, through the jumper cap can realize the output is high potential output or pull down the output.4, the board above the 4-way 817 are independent, you can realize different voltages at the same time control and so on.5: board size: length: 48mm; width: 38mm; long side hole spacing: 42mm; wide side hole spacing: 32mmTranslated with www.DeepL.com/Translator (free version)

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
