Industrial control is machines and equipment or production process in the absence of direct manual intervention, according to the expected goal to achieve measurement, control and other information processing and process control collectively. In the industrial control system, there are all kinds of interference, the use of optical isolator can achieve isolation, anti-jamming effect.

Instrumentation is used to detect, measure, observe, calculate various physical quantities, material composition, physical parameters and other instruments or equipment, is a set of devices or machines prepared for a specific purpose, such as oscilloscope, power meter, tester, multimeter, etc.

In the context of global energy reduction and the promotion of energy conservation and emission reduction, the proportion of new energy vehicles in the market is increasing day by day, and there is a trend of comprehensively replacing fuel vehicles. Cars are the means of transportation that shoulder the mission of personnel transportation safety.

Household appliances liberate people from heavy, trivial and time-consuming housework, create a more comfortable and beautiful, more conducive to physical and mental health of human life and work environment, provide a variety of cultural entertainment conditions, is a modern family life necessities. The high power and high voltage of household appliances will have certain security risks, which requires the use of isolation devices to eliminate the unsafe factors caused by the great pressure difference during the level conversion.  

Photovoltaic power generation is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. It can be used with energy storage systems to maximize energy utilization.
