Optoisolators are electronic components that protect user systems from voltage fluctuations and surges. They do this by electrically separating user systems from incoming power sources, preventing electrical damage from occurring to valuable equipment. PS9587-AX is a type of optoisolators that is categorized as “Logic Output”. Its unique application field and working principle are described below.

Application Field and Uses

PS9587-AX is a type of optoisolator designed specifically for logic outputs. This type of optoisolator is used to provide an additional layer of isolation between a user’s system and an incoming power source. It is frequently used in logic circuits, such as those found in microprocessors, to ensure the safety of important electronic systems. Its primary function is to protect these systems from the effects of voltage fluctuations and surges.

As a logic output optoisolator, PS9587-AX is able to convert logic signals into isolated logic signals. This allows a user’s system to be protected from the negative effects of incoming power sources without compromising the integrity of the logic signals. It is also capable of providing protection from reverse currents. This is achieved by using two transistors to create a full diode bridge. The resulting current flow is then redirected away from the user system and into a safer path.

Working Principle

The working principle of PS9587-AX is quite simple. Basically, this optoisolator uses an infrared LED (Light Emitting Diode) and an integrated photo detector to provide the isolation. Incoming logic signals send a voltage to the LED, which then emits a light beam. This light beam is detected by the integrated photosensor. The output of this photosensor is then used to drive the logic output. This ensures that the user system is electrically isolated from the incoming power source, thus protecting it from any potential damage.

However, the photo-detector of PS9587-AX is not only used for detecting the infrared light emitted by the LED. It can also be used to detect changes in surrounding illumination levels. By doing this, the optoisolator can provide additional protection against unwanted voltage fluctuations. For example, if the illumination levels suddenly change, the photo-detector will trigger the LED to emit an additional light beam, thus ensuring that the logic output is kept isolated from the incoming power source.

In addition to protecting user systems from voltage fluctuations, PS9587-AX is also used to provide reverse voltage protection. This is achieved by using two transistors to create a full diode bridge. Whenever a reverse voltage is detected, the two transistors will act as a diode and prevent current from flowing into the user system. This helps to ensure the longevity of valuable equipment.

Conclusion

In conclusion, PS9587-AX optoisolator is a type of logic output optoisolator specifically designed for protecting user systems from incoming power sources. This optoisolator uses an LED and a photo-detector to convert logic signals into isolated logic signals, thus ensuring the safety of important electronics systems. In addition to providing protection from incoming power sources, this optoisolator is also capable of providing reverse voltage protection, thanks to its full diode bridge. Therefore, PS9587-AX can be a useful component for users looking to ensure the longevity of their valuable equipment.
