FAQ about Digital Isolators
-
1. What is the difference between optical isolators and digital isolators?
The main difference between optical isolators and digital isolators lies in their working principles, performance and application scenarios.
Working principle
Optical isolators (also known as optocouplers) use light to transmit signals through isolation barriers. It emits light through light-emitting diodes (LEDs), and photosensitive transistors receive light and convert it into electrical signals, thereby realizing isolated transmission of signals.
Digital isolators use capacitive or electromagnetic isolation technology to transmit signals. They achieve signal isolation transmission through capacitive coupling or electromagnetic isolation, with higher transmission rate and lower power consumption.
Performance comparison
Optical isolators have a slower transmission rate, usually several megabits per second, and require additional circuit components, increasing costs and PCB area. In addition, the aging problem of optical isolators is more serious, especially when working in a high temperature environment.
Digital isolators have higher transmission rates, lower power consumption and smaller size. They also have better common mode transient immunity (CMTI) and longer service life, and are more integrated, and can integrate multiple functions such as input filters, transceivers and output enable options. Digital isolators have no temperature drift problems and better performance consistency.

2. What is an electronic isolator?
An electronic isolator is an electronic component used to achieve electrical isolation in a circuit. It is mainly used to prevent the flow of current while allowing electrical signals or energy to be transmitted in some way. It ensures the safety of equipment and people by isolating the electrical connections between different circuits.
Definition and function
Electronic isolators effectively isolate the electrical connections between two circuits by using components with special structures to prevent current, signals or interfering substances from being transmitted between the two circuits. Its main functions and effects include:
Safety isolation: prevent high voltage or high power circuits from affecting low voltage or low power circuits, and protect the safety of equipment and personnel.
Electrical isolation: prevent noise, surges and interference in the power supply from propagating to other circuits, and improve the stability and reliability of the circuit.
Signal isolation: isolate the ground loop during signal transmission to avoid signal interference and signal loss.
Baud isolation: in digital communication or data transmission, isolate the data transmission loop to protect the receiver from potential electrical interference and attacks.
Types and application areas
There are many types of electronic isolators, including:
Air isolator: uses air as a medium, with a simple structure and high reliability.
Gas isolator: uses gas medium to achieve circuit isolation, suitable for high voltage environments and high power circuits.
Liquid isolator: uses insulating liquid as a medium, suitable for high voltage scenarios, with good insulation performance and heat dissipation effect. -
3. What is the purpose of isolators?
The main uses of isolators include signal isolation, circuit protection and system performance improvement.
Signal isolation
Isolators effectively prevent signal interference and distortion by completely isolating input signals from output signals electrically. In complex electronic systems, various signals need to be transmitted between different devices and instruments, but due to the presence of electromagnetic interference, signal attenuation and other factors, the signals may be interfered or distorted during transmission. Isolators use the linear optocoupler isolation principle to ensure stable signal transmission and avoid interference and distortion.
Protect circuit safety
Isolators can isolate power and load to ensure safe operation of circuits. In the power industry, isolators are an indispensable component of power substations and transmission systems. They can isolate high-voltage power supplies in power systems and protect the safety of personnel and equipment. In addition, in the chemical, pharmaceutical, food and other industries, isolators are also widely used in the isolation and insulation of power supply systems to ensure the safety and stability of the production process.
What is an intelligent isolator?
An intelligent isolator, also known as a signal isolator, is a device that converts input signals into outputs using the linear optocoupler isolation principle. It usually consists of four parts: input signal processing unit, isolation unit, output signal processing unit and power supply.
The main functions of the intelligent isolator include:
Signal isolation: The input, output and working power supply are isolated from each other, which can effectively solve various signal interference problems existing on site and ensure the purity and stability of the signal.
Signal processing and conversion: It can perform signal processing conversion and distribution according to site requirements, support the input of single-channel or dual-channel two-wire current signals, and transmit and output isolated single-channel or dual-channel current or voltage signals.
Multi-channel processing capability: For scenarios requiring multi-channel signal processing, intelligent isolators can provide perfect solutions and are widely used in various industrial control systems.
Intelligent isolators are widely used in the field of industrial automation, especially in major projects in environmental protection, electric power, metallurgy, equipment manufacturing, petrochemical and other industries. They can effectively deal with complex signal interference problems and ensure accurate data transmission.
