Digital Isolators are develop from Isolation technology to provide a safe and reliable signal transmission between two circuits. Namely, they possess electrical insulation for electrical isolation, automatic current limiting when over-voltage is detected, and the ability to provide 4~20mA signal output. SI8420AD-D-IS isolation product is a new type of isolator based on the industry-leading isolator principles. In addition to basic functions, it provides a high degree of accuracy, stability, synchronous and fast response in various kinds of application fields.

The SI8420AD-D-IS is suitable for extreme working environment including temperature, vibration, EMC and other harsh conditions. It can be used for digital isolation in core industry in safety integrity level (SIL) applications. With an excellent performance, it is ideal for protection and automation in industrial networks, data acquisition server, stepper motor, robotic control and other low power systems. It can be used for any industrial application with an isolation voltage up to 1000V. It also provides significant benefits to systems that require a fast, wide dynamic range of isolated signals.

The working principle of the SI8420AD-D-IS isolation product is simple. It is able to provide two-way transmission of digital signals between two independent circuits with the highly efficient and powerful transformer. The signal transmitted from one side of the circuit is passed through the transformer and is then transmitted to the other side. In this way, two different circuits can communicate without any interruption. To make the signal transmission more secure and reliable, the transformer is equipped with a high-resistance output filter which eliminates any noise or interference and also reduces the effect of power supply interference.

In addition, the SI8420AD-D-IS also features a built-in voltage regulator which automatically regulates the voltage and provides a stable electrical source for the system. It uses low-power has advanced power conserving techniques which saves power consumption and ensures minimal power consumption. It also has various current thresholds and enables a current range from 4mA to 20mA.

The SI8420AD-D-IS isolation product is designed to provide reliable signal transmission and security in industrial automation applications. It provides safety and flexibility, as well as high accuracy and reliable transmission with low power consumption. This makes it an ideal choice for industrial network applications. Moreover, it also offers a long service life and extended operational longevity due to its insulation with high mechanical strength. This makes it suitable for use in harsh and extreme working environments.
