1 optical coupling isolation module
5.0 pitch screw terminal is convenient for wiring
The default input optocoupler terminal voltage is 5V. In addition, 12V -30V voltage input can be ordered to contact the shopkeeper
This board role
1 MCU output level to drive the motor motor and other perceptual devices to do isolation function anti-interference protection MCU part of the circuit.
2 MCU output level is low, the driven module driving voltage is high for level matching such as some PLC input to 24V voltage can be used to convert this module
3 Used for inverter, can invert the input signal output
For example, if the output signal level of a sensor is 12V and the voltage of a single chip microcomputer is 5V, this module can be used for isolation and detection.
5 current amplification, such as MCU output current is too small to drive some circuits, you can use this module for amplification
.

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.
