NE555 Pulse Frequency Generator Adjustable Duty Cycle Signal Generator Board Module

1、Output with LED indication,when the LED is low, the LED is off, and when the frequency is low, the LED is blinking,more clear and convenient.

2、Output frequency range grade is optional,use the shorting cap to select) to make the output frequency more continuously adjustable.

3、Generate square wave signal, adjustable pulse.

4、Compact and practical design makes it works more stable.

5、Widely applicable to multiple occasions,suitable for many equipments.Item Type:Pulse Frequency Generator

Size:2.9 x 3.6cm / 1.14 x 1.42in

Fixing Hole Distance:22.5 x 30.5mm / 0.89 x 1.2in

Main Chip:NE555

Input Voltage:5V~15VDC.When 5V is supplied, the output current can be around 15mA; when 12V is supplied, the output current can be around 35mA.

Weight:Weight: 10 g / 0.35 oz(approx.)

Input Current:>=100mA

Output Amplitude:4.2V V-PP to 11.4V V-PP. (The output amplitude will be different depending on the input voltage)

Output current: ≥15mA (5V power supply, V-PP is greater than 50%), ≥35mA (12V power supply, V-PP is greater than 50%)

Output Frequency:

Low Frequency: 1Hz ~ 50Hz

Intermediate Frequency: 50Hz ~ 1kHz

Medium And High Frequency: 1KHz ~ 10kHz

High Frequency: 10 KHz ~ 200 KHz

Period T = 0.7 (RA + 2RB) C

RA and RB are adjustable from 0 to 10K;

C=0.001UF in low frequency gear;

C=0.1UF in the intermediate frequency file;

Medium and high frequency file C=1UF;

C=100UF in high frequency, so the frequency of the waveform can be calculated by yourself..w-e-text table td,.w-e-text table th,.wang-edit-text table td, .wang-edit-text table th{border: .5pt solid #000;};.w-e-text table,.wang-edit-text table{border: 1px solid #000 !important;}
