Optoisolators, also known as optocouplers, are optoelectronic devices used to electrically isolate and transfer control signals between two circuits. The OLS700 optoisolator is a type of optocoupler that combines an emitting element, usually an infrared LED, and a photodetector, such as a phototransistor, to provide electrical isolation in an electrical system. This optocoupler offers high isolation and can be used in numerous applications.

The OLS700 optoisolator consists of an infrared LED connected in series with a phototransistor, which is contained in a plastic molded package. The input current of the LED is proportional to the applied voltage and can range between 0.5 to 1.3mA. The transistor has a maximum collector-to-emitter voltage of 70V and can withstand operating temperatures from -40°C to +100°C. Its power consumption is typically only 2 mW and its isolation voltage is 1kV, making it ideal for use in industrial environments.

The OLS700 optoisolator can be used in various applications, such as level shift, circuit protection, and surge protection. For level shift applications, the optocoupler can be used to convert digital logic levels from one circuit to another. It can also be used to provide isolation between two logic circuits, or between two levels of power supply. The isolator can also be used in low power, high speed circuits, where it acts as a gate between two signals for switching. The optocoupler can also be used for surge protection, as it can be used to detect a fault and disconnect the load from the supply.

The working principle of the OLS700 optoisolator is based on the transfer of voltage across an optical barrier created by the LED and phototransistor. When a voltage is applied to the LED, it emits a light beam that is picked up by the phototransistor. This light is then converted into a current that is used to control the output voltage of the optocoupler. The output of the optoisolator can also be used to control other components in the circuit, such as relays or other actuators.

The OLS700 optoisolator has many advantages, such as high isolation, low power consumption, and a wide operating temperature range making it suitable for industrial and commercial applications. It is also reliable and easy to install, requiring minimal maintenance. It can provide high efficiency and noise immunity for its many applications.
