Digital Isolators

Digital Isolators are used to provide electrical isolation between two or more components in an electrical system. Isolation is necessary for safety and compliance with industrial standards of electrical isolation. The SI8610ED-B-IS digital isolator is a device that facilitates communication between two components while maintaining isolation. The circuit provides bi-directional communication between two optically isolated channels, thereby allowing communication between different components without direct electrical connection.

Application Field

The SI8610ED-B-IS digital isolator is designed to be used in high-speed, multi-channel industrial applications which require electrical isolation. It is compatible with the RS-485/RS-422 protocol and can support data rates of up to 10 Mbps. It can also be used for connecting technologies such as Ethernet, CAN Bus, PROFIBUS, and Fiber Optic. In addition, this isolator is designed to meet the requirements of industrial applications while still providing a high level of EMC robustness.

Working Principle

The SI8610ED-B-IS digital isolator uses opto-isolation technology. The device consists of two optically isolated channels, each with a receiver and transmitter. When a signal is sent over one of the channels, it is detected by the receiver and converted into a visible light signal. The signal is then sent over the other channel via light transmission, and detected by the second receiver. The signal is then converted back into an electrical signal, allowing two-way communication between the two channels without requiring any electrical connection between the two channels.

The device also utilizes two high-speed digital isolators, each capable of transferring data at 10 Mbps. Each of these isolators consists of a signal transmitter, receiver, optocoupler, and discrete components. The optocoupler is an optically isolated component that utilizes a light emitter and detector to allow for fast response and extremely high isolation resistance. The discrete components provide protection against EMI/RFI interference and allow for a high level of robustness.

The SI8610ED-B-IS digital isolator provides a cost-effective solution for providing electrical isolation between two or more components while still providing a reliable data transfer rate. It can be used in a variety of industrial applications and provides a high level of EMC robustness. In addition, the device requires no direct electrical connection, eliminating the need for expensive wiring and cabling.
