brief introduction： An optocoupler is designed to send an electrical signal between two nodes without an actual direct electrical connection via a conductive conduit. The most important purpose for this type of device is for electrical protection. Since a signal is being transferred without a physical medium, the optocoupler creates an isolation in the circuit which is immune to very high voltage surges well into the thousands of volts. A common example of this would be a lightning strike or inductive spikes. The d
