Digital Isolation

Hidden Costs of Isolated RS-485 Optocoupler Design Optocouplers, also known as optical isolators or optoelectronic couplers, have been used for over 40 years to achieve current isolation in electronic circuits. Optocouplers use LEDs and phototransistors to communicate signals without transmitting current. As a low-cost solution, optocouplers have remained popular. But considering the advancements in digital … Read more
