ماژول تایمر NE555 مولد پالس

ویژگی ها :

این ماژول قابلیت تنظیم زمان تاخیر از 0 ثانیه تا 120 ثانیه را دارد .

مقدار ولتاژ خروجی را با  LED نشان می دهد .

مجهز به کلید تریگر می باشد .

وقتی ماژول در حالت تریگر نباشد سطح ولتاژ خروجی پایین است و بالعکس .

این ماژول قابلیت اتصال به ماژول رله را دارد .

مشخصات پایه ها:
(1) Power supply: Input voltage: 5V-12VDC. 5V supply output current is about 10MA; when 12V power supply, output current is about 30MA;
(2) Frequency: 5 bands (Found)
    J1 file: 0.6Hz ~ 25Hz 
    J2 profile: 7Hz ~ 300Hz 
    J3 file: 50Hz ~ 2.5kHz 
    J4 block: 350kHz ~ 6.6kHz 
    J5 block: 6.7kHz ~ 180kHz
Adjustable duty cycle range: 0.4-0.99
(3) LED output indication, the low level LED lights, LED off high, led flashing speed indicates the output frequency variation; except jump cap choice of different frequency bands outside, RV1 can adjust the frequency adjustment, regulation led flashes can be seen as adjust the frequency change corresponding to the change;
(4) Input Current: ≥100MA
(5) Output voltage: 4.2V - 11.4V peak (with supply voltage variation).
(6) The output frequency is calculated: Period T = 0.7 (Ra + 2Rb) C Ra, Rb is 0-10K adjustable;
(7) Input: VCC GND Output: VCC OUT GND here input voltage and output consistent with the purpose of user-friendly, you can follow-up power supply. OUT is the output signal frequency.
