Specification:  1.Board Size:73*15mm2.Functuon:Testing whether AC 220V is existed 3.Ouput TTL Level:can use SCM to test,voltage is 3-5V4.Adaptive to PLC 24V level  Product Introduction:  Output TTL level can be detected with the microcontroller. The power supply can be 3-5VCan also access PLC24V levelThen the PLC input terminal of the PLC COM power supply 24V input termination of the board signal output OUT, optocoupler board GND power negativeBlue 2P 5.0 terminal connected to 220V voltage3P terminal connected to the microcontroller input.  Safety warning:  When the power module in the power of the board after the white wire frame can not touch any device .. because it is high voltage. Note the safety of electricity.

Feature:  Functuon: Test whether AC 220V is existed Ouput TTL Level: can use MCU to test,voltage is 3-5V Output can connect PLC 24V  Wiring:  When connecting the PLC input, the PLC's COM terminal is connected to the 24V power supply, the input is connected to signal outputs S1-S8 of the board, optocoupler GND is connected to the power supply negative. Blue 5.0 terminal is connected to 220V voltage, yellow pin signal output. When the 220V voltage is normal, it output low level; when 220V is powered off, it output high level.  Note: Do not touch any part of the white wire frame on the board after the module is powered on, because it is high voltage. Pay attention to electricity safety.

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.
