An opto-isolator is an electronic component that transfers electrical signals between two isolated circuits with light. It is also known by different names like; photocoupler, optical isolator, or optocoupler. Generally, an Opto-isolator prevents higher voltages from influencing the system obtaining the signal. An optocoupler integrated circuit combines optical elements that perform as a simple switch. These are very simple to use in different electronic circuits for isolation between circuit … [Read more...]
