OPPLE electrical components Germany OPPLE model OPPLE price

OPPLE electrical components are a new type of contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, triacs, and other semiconductor devices) to achieve contactless and spark-free connection and disconnection of circuits, hence it is also called a "contactless switch". A solid-state relay is a four-terminal active device, where two terminals are input control terminals and the other two are output controlled terminals. It has both amplification drive and isolation functions, making it very suitable for driving high-power switching actuators, compared to electromagnetic relays
