NE555 delay module monostable switch relay delay on-off switch (12V) automotive electrical delay brief description]

1. size: 6.8CM * 2.1CM

2. main chip: NE555

3. working voltage: DC 12V

4. features: 1, When the power is turned on, the relay is delayed (this module only has the function of delayed suction and does not have the function of delayed disconnection unless the power is cut off). Specifically, after power-on, the relay will not suck immediately. At this time, the state of the relay output is: normally open and publicly disconnected, normally closed and publicly conductive; After a delay of 1-10s (delay adjustable), the relay sucks. At this time, the state of the relay output is: normally open and publicly conductive, normally closed and publicly disconnected; As long as the module is continuously energized, this state (relay suction and state) will be maintained. Test phenomenon: after power-on, the red power indicator light will light up. after a delay of 1-10s, the relay will suck and a "click" 1 will be heard, and the blue relay suction and indicator light will light up.

2. Adjustable delay time (0~10 seconds) 4, increase the potentiometer can increase the delay time 5. Increasing the capacitor C1 can increase the delay time 6. With input power indicator 7. With relay pull-in indicator light 8, can control AC 220V/10A equipment. (Control equipment 2000W) 9. With relay freewheeling protection. 10. Delay time formula: T = 1.1RC. For example: capacitor 100uf resistor 100K T = 1.1*100000*0.0001=11 seconds

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.
