Optocoupler isolation Signal isolator is an electronic component that achieves signal isolation by means of an optocoupler. It attains electrical isolation between the input and output by converting an electrical signal into an optical signal and subsequently converting the optical signal back into an electrical signal. Such a design not only enables effective signal isolation but also enhances the anti-interference capacity and stability of the system. The following is a detailed account of the optocoupler isolation signal isolator and its pros and cons.
Introduction of Optocoupler Isolated Signal Isolators
The optocoupler isolation signal isolator mainly consists of a light-emitting diode (LED) and a photosensitive transistor. When the input receives an electrical signal, the LED will emit light of the corresponding intensity, and the photosensitive transistor receives the optical signal and converts it into an electrical signal for output. As there is no direct electrical connection between the input and the output but is coupled solely by optical signals, high electrical isolation performance can be attained.
Main Functions and Applications
Signal Isolation: The optocoupler isolation signal isolator is primarily employed for the isolated transmission of signals, particularly in high-voltage environments, which can effectively safeguard the low-voltage circuits from the influence of high voltage.
Level Switching: It is capable of converting between different voltage levels, such as from 3.3V to 5V.
Anti-Interference: Owing to the isolation property of the optocoupler, it can efficaciously suppress noise and interference and enhance the stability of the system.
Long Service Life: The service life of the optical coupler is prolonged and can exceed several decades.
Widely Applied: Optocoupler isolated signal isolators are extensively utilized in electrical insulation, level conversion, drive circuits, switching circuits, communication equipment, and microcomputer interfaces, among other fields.
Advantages of Optocoupler Isolation Signal Isolators
Adjustable Duty Cycle: The duty cycle of the optocoupler isolation signal isolator can be adjusted as necessary, presenting high flexibility.
High Isolation Voltage: It can operate stably in high-voltage environments, and the isolation voltage can reach several thousand volts.
Strong Anti-Interference Ability: As there is no direct electrical connection between the input and output, the optocoupler isolation signal isolator boasts strong anti-interference ability and can effectively suppress voltage noise.
A Broad Range of Transmitted Signals: It can transmit signals from DC to several megahertz and is particularly suitable for signal feedback applications.
Long Service Life: The optical coupler has an extended service life and can function stably for an extended period.
Compact Size and Light Weight: The optical coupler is diminutive in size and lightweight, suitable for application in various miniaturized apparatuses.
Low Cost: The price of the optical coupler is relatively inexpensive and enjoys high cost-effectiveness.
