Flashing light attached to it,with frequency of the ringging tone. The circuit uses power from the telephone line. Quote and Order boards in minutes on https: How to builds You datzsheet builds this projects with make the PCB before and then puting All components in this circuit as Figure 2 except of the piezoelectric transducers can be assembled into a perforated board.

KA2411 Datasheet

Leave a Reply Cancel reply. This circuit is easily to build, because it uses a single IC as shown in figure below. When IC1 is given the supply volt as I said, it will generator a ringing signals through the R5, to drive the Piezoelectric transducer BZ1 be a bell tone out to hear.


We do not need a new phone. Which is about 20 Hz. Learn how your comment data is processed. Then try to connect the telephone lines, then call come in, will be have hear the ringing tone, if the sound is not impressive, you can change the RC with formula given above.

Wing Shing Computer Components

We hear the sound of the Oscillator 2 series, which differ by the output frequency chops to be a frequency generator circuits. C3 For a maximum frequency is calculated from.

The D1 detect a positive signal, and the 4 LED. This adtasheet is relatively loud. LED can be connected in series to increase, but less in proportion to the light.

Telephone bell ringer circuit using IC-KA – ElecCircuit

The detect ringing signal tone dataseet with light and sound. Many electronics circuits and projects for learning in simple ways. By D2 to detect, only a negative signal,One extreme to the other end of the wire loop. It is easy to use and good quality, Do not enter the power supply.


Figure 2 PCB and the components layout. Signal voltage is reduced down to approximately 10V.

The ringing tone light, we may reduce the R5 for low down. Which as Detect ringing signal tone circuit Or ring tones on the telephone line, a signal incoming calls. This Telephone bell ringer circuit for generating the electricity bell in the k2411 telephone.

You should check the accuracy.
