Digital Isolators are a type of circuit that provides electrical insulation between two or more circuits or even subsystems. This allows for protection against electric shock, potential damage caused by incorrect usage, and even potential data loss due to electromagnetic interference. The SI88321BC-ISR is one of the latest digital isolators that utilizes the new Isolated Switch Relay (ISR) technology for a robust level of electrical isolation. It can transfer analog signals and digital signals all while providing complete galvanic isolation between the two separated circuits.

Application Field

The SI88321BC-ISR digital isolator is ideal for a wide range of applications, from industrial automation to simulation and control systems. It can transfer signals within industrial control segments, while also providing a high degree of separation from other segments. Additionally, it can also be used to isolate power between two or more circuits that may have different power supply levels.

Working Principle

The SI88321BC-ISR uses a patented Isolated Switch Relay (ISR) technology that works by setting a barrier between two circuits so that electrical signals cannot pass directly between them. Instead, the digital isolator uses controlled electric fields to transfer signals instead of a direct current connection. The isolation provided by this device is very strong, capable of providing up to 6.5 kV DC isolation, making it a reliable and secure solution for industrial automation, control systems, and simulation.

The device also comes equipped with a range of features to ensure the highest quality of signal transmission. These include: on/off control, an adjustable loop time, and a fast start circuit. Additionally, the SI88321BC-ISR also has an integrated over-voltage protection, over-temperature protection, and short-circuit protection for added safety.

The SI88321BC-ISR digital isolator is an ideal solution for industrial automation, control, and simulation systems. It provides an extremely secure level of electrical isolation, as well as a range of features that ensure a high quality of signal transmission. Its robust insulation ensures that it can be used in a wide range of applications without the risk of damage or data loss.
