Does an optocoupler have a normally closed circuit
An optocoupler must have current flow in its output, and it cannot provide what is called a simple “dry circuit” contact-closure which an electromechanical relay offers. However I have a situation where I'd like the circuit controlled by the opto to be normally closed, mainly for the failure state but also so that the opto's led doesn't have to be activated for 99% of the time. In this guide, you'll learn how they work and how you can use one in your own projects. As an isolator, an optocoupler can prevent high voltages from affecting the side of the circuit receiving the signal.
