The following is a step-by-step guide for setting up the evaluation board, including connection to power sources and signal generators. An optocoupler (or opto-isolator) is a component that transfer signals between circuits using light. In this guide, you'll learn how they work and how you can use one in your own projects. It provides complete isolation between the input and the. There are many different applications for optocoupler circuits, so there are many different design requirements, but a basic design for an optocoupler providing isolation for example between two circuits, simply involves the choice of appropriate resistor values for the two resistors R1 and R2. This HCNR201 High Bandwidth Evaluation Board User Guide provides the necessary information and instructions to effectively evaluate and utilize the Broadcom® HCNR201 high-linearity analog optocoupler in your applications. There is a is a light emitting diode with a phototransistor inside the optocouplers, both of them are isolated from the external environment of the.
