What exactly is the function of opto coupler or opto isolater?
ive used opto coupler to get the digital signals from the parallel port(0x0378).. I knew that there is a LED inside the opto coupler that burns according to the digital signal given... Why shouldnt be the digital signal from the port directly amplified without the use of opto coupler?
The clue is in it's name-opto-ISOLATOR. So that's the function--of isolating, typically analog section from the digital one, or the high voltage section from the low-voltage one.
If something goes wrong in one section, the other section should be protected. Take one example. You have designed a micro-controller based circuit to operate some machinery. Now machinery being all mechanical, some unexpected problems are bound to arise, like a jammed fly-wheel, which in turn draws very heavy current from your circuit. So associated sub-section of your circuit will get burnt, but not the micro-controller section, since most probably you would have isolated the digital signals from the driver analog ciruitry using opto-isolators.
