Hello Everyone, hope all is well with everyone.
I had a question ( for the past 3 months) about Electronic devices that control regular appliances that run on 120 volts. For the sake of simplicity I will use a modern dishwasher as an example.
What is the device that is in between the "electronics side" of the system and the "electrical side" of the system?
For example lets take the control panel of the dishwasher shown here. http://www.quietestdishwashers.com/dishwasher-images/GLD4900PBB.JPG
I am sure the 120 volts that's reaching the motor doesn't and shouldn't go through the whole delicate electronic circuitry before reaching the motor. ( I am thinking that much of a voltage would end up frying the delicate electronic components, micro-controllers etc in seconds.)
So there should be some "thing" which takes the user input and then process the input and then sends the actual 120 volts and the high number of amps to the motor or what ever.A thing that is a bridge between the electronic and electrical system of the dishwasher.
What is that device/system/relay or whatever that does this Electronic- Electrical mediator job? I cant imagine the power directly going through the electronic control circuitry !
I cant imagine that a simple transistor can take a small voltage as an input signal at its base and end up sending 120 volts through the collector emitter region!
I apologize if I was going around in circles or if i didn't explain my question well but i can re phrase it if you want.
Thanks a lot for the replies!
