Optoisolators - Logic Output, such as the PS9303L2-AX, are optokopplers which are used to transfer electrical signals between two different circuits while maintaining a separate electrical isolation. It is also known as a photocoupler, optical coupler, optogate, optical isolator or optoisolator.

An optoisolator is an electrical component which converts an electrical signal into an optical signal which is then decoded by a receiver. It works by using an infrared light-emitting diode (LED) to sense the changes in incoming signals and convert them into an electrical signal that can be interpreted by a receiver. This isolator then serves as a shield against high voltages, electromagnetic interference and other types of noise or disturbance.

The PS9303L2-AX optoisolator is a high-efficiency, low-cost device offering a wide range of applications. It features an AC output with a voltage range from 3.5V to 12V, and a maximum forward current of 250mA. It also has a wide working temperature range of -40oC to 85oC and a maximum output current of 40mA. This optoisolator is also UL and CB certified.

The PS9303L2-AX optoisolator is used in applications where it is necessary to isolate signals between two different circuits, such as motors, lights, sensors, switches, and more. By using this optoisolator, a voltage can be applied at one end and the signal will be transferred to the other end without interference from high voltages, electromagnetic interference, or other sources of noise. This makes the device ideal for medical equipment, automotive applications, alarm systems, power control systems, and other industrial applications.

The working principle of the PS9303L2-AX optoisolator is simple. An infrared LED is placed on one side of the isolator and a phototransistor is placed on the other side. The LED emits infrared light when an electrical signal is applied. This light is then received by the phototransistor, which generates an electrical signal that can be read by the receiving circuit. This optoisolator prevents any direct electrical connection between the two sides and instead uses an optical link.

In conclusion, the PS9303L2-AX optoisolator is an ideal device for applications where extreme electrical isolation is required. The device is capable of providing safe transmission of signals between two circuits while acting as a shield against high voltages, electromagnetic interference, and other sources of noise. It is a reliable, low-cost device which is UL and CB certified, and can be used in a wide range of applications such as medical equipment, automotive applications, alarm and power control systems, and more.
