WebOct 14, 2004 · The I 2 C-bus is fabulously popular and successful as a low-cost way to attach chips together in small embedded systems. In some systems, though, these chips need to be opto-isolated to avoid damage from stray electrical current in harsh environments. This hands-on article shows how to isolate I 2 C devices without giving up … An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. Opto-isolators prevent high voltages from affecting the system receiving the signal.
