The MOC3063S is an optocoupler, a device used to separate one component of an electrical circuit from another. This division is crucial, it will prevent rogue electrical signals from messing with the rest of our circuit. It also keeps some of the more easily-damaged parts from being destroyed. Its like a boundary of safety that keeps everything secure and running as it should.
This is an excellent solution to separate sections of a circuit for electrical projects that you are working.null This thing separates signals from one another very well, it is simple and easily implemented way of keeping the things apart sharing nothing but operating voltage through two small components LED and a part called transistor — that can be biased (made to conduct) by light. This way, they can communicate messages in a small gap of air.
Let’s break that down a bit. The MOC3063S is a optoisolater and it has an emitter LED on one half of the package, followed by transistor in the other side. The other side, which terminates in a transistor to short towards gnd goes on output. You can see the LED lights up when the input signal is high. That light turns on to turn the transistor opens a path for output signal. However when the input signal is low, then LED will turn off and so as transistors goes to OFF Mode. Seeing as the output signal is always completely important from the input signal, This design maintains this sterilized gap between them.
It can come in handy for much more than just these instances. For instance, if you are designing a power supply you would probably want to keep the high-voltage parts far away from low-level circuits in order not to fry them or give yourself life-threatening shocks. Or maybe you are creating a data sending system and want to ensure your signal wires stay free of noise so the signals transmit properly and give good information.
Well, this MOC3063S can do even better! And it can use for triac driver optocoupler too, where they do require to control AC power in the applications circuits. A trianc is a unique component capable of switching AC power on and off. With the MOC3063S in fitting to take control of a triac (image, right), you can say bye-byezee on and off states as well as PWM for lights, heating elements conveyors or any other device powered by good old AC.
So how does this work? When the input signal is high, it causes a pulse of current in the MOC3063S triac driver optocoupler. This pulse then triggers the triac on, letting the AC in to feed your devices. When the input signal goes low, that current pulse is gone out and triac turns off stopping power flow. This incredibly user-friendly in managing the power consumption for multiple devices around your house and workplace as well.
If your system is for data acquisition, you will need to consider different paths running isolation barriers so the noise from noisy power supplies are not coupled on top of other signals interfering with accurate measurements. The MOC3063S again is a simple and effective way to achieve this isolation, so you can get back to the fun part of bringing your project together.
