Optoisolators - Logic Output

The PS9821-2-V-A is a three pin optoisolator that is used mainly in logic output applications. This optoisolator series has a digital output signal and is suitable for phototransistor output. It has a variety of features that makes it an ideal choice for many applications.

The PS9821-2-V-A isolation barrier consists of a light emitting diode (LED) connected to an integrated photo sensitive transistor. The power input to the LED is isolated from the transistor output by a special optical layer. This isolation barrier prevents electrical signals or noise from passing between the input and output pins. It ensures that the LED and transistor operate independently, thus providing reliable operation.

The application field of this optoisolator is mainly logic output. It is often used as an interface between two parts of the same circuit, or between two different circuits, where isolation is necessary. As it provides a very high degree of isolation between the two parts of the circuit, it is very suitable for industrial, automotive and other applications.

The working principle behind this optoisolator is quite simple. When the input voltage is applied, the LED emits light that is received by the photo sensitive transistor. The transistor will then produce an electrical output signal in response. The output signal can be used to control various devices or to actuate other electronic circuits. The output signal is isolated from the input signal, meaning that any changes in the input voltage are not passed through to the output.

The PS9821-2-V-A optoisolator is used in a wide variety of applications due to its reliable design, wide operating voltage range and low power consumption. It is a great choice for highly reliable applications as it can withstand high temperatures and high vibration levels. Its small size makes it very suitable for connecting external cables and wiring, and its low profile makes it suitable for installation in confined spaces.

The PS9821-2-V-A optoisolator provides a reliable and economical solution for logic output applications. Its simple design and easy installation make it ideal for industrial, automotive and many other applications. Its low power consumption makes it especially suitable for applications that require long-term operation.
