In recent years, with the popularization of the Internet of Things, big data and cloud computing in the industrial field, a new round of changes is taking place in the global industry. In order to achieve intelligence, low power consumption and high efficiency output, more components and nodes are introduced into industrial applications, and the number of electrical components continues to increase, which also makes high voltage, magnetic field and noise continue to increase. In this environment, circuit designers use optocouplers to isolate high voltages and isolate unwanted noise signals, increasing system robustness and reliability.

In this kind of industrial environment, Orend SCR optocoupler series can be used to realize the isolation of high voltage and unnecessary noise signals. Through isolation, sensitive circuits can also be protected from high voltage disturbance interference and damage, so as to ensure the normal operation of the system function, prolong the service life of the system, and protect the personal safety of operators.

Optocoupler relays can greatly improve the signal-to-noise ratio as terminal isolation components in long-line transmission of information. As an interface device for signal isolation in computer digital communication and real-time control, it can greatly increase the reliability of computer work.
