Working Principle

The SI88243EC-ISR digital isolator uses a unique system of capacitive compartmentalization to provide isolation between the two connected buses. This system is able to isolate signals up to a rating of 2500V peak, allowing for safe and reliable communication. The isolator works by using a low-frequency AC signal to travel between the two connected ports. The AC signal passes through the isolator, and the isolator\'s two isolated ports convert the low-frequency AC signal into a high-frequency digital one. This high-frequency signal is then able to pass through the isolator without any degradation. The high-frequency signal is then converted back into a low-frequency signal inside the isolated digital environment, and the data is then transferred securely and without any interference between the two connected buses. This system ensures high-speed, secure, and reliable data transfer between the connected ports.

Conclusion

The SI88243EC-ISR digital isolator provides a reliable, secure and high-speed communication link for a variety of industrial applications. It is small in size, low in power consumption and highly reliable, and it offers excellent performance and data transmission in harsh environmental conditions. The isolator is also easy to install and maintain, and it is cost-effective, making it a perfect choice for a wide range of industrial applications.
