What are the different models of modules with optocouplers

Optocouplers can be categorized by output element type, application environment, and functional characteristics. This unique design ensures that the two circuits remain electrically isolated. They typically consist of an LED on the input side and a photosensitive device – such as a phototransistor, diode array, or triac – on the output. From relay sockets to pluggable relay and optocoupler modules – WAGO delivers versatile, high-performance solutions for every application. With the industrial automation market projected to grow significantly in 2025, the demand for reliable circuit isolation has. 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.
