PC851XIJ000F

Optoisolators are relays that are made of an electrical insulator and two layers of electrical conductors. The two layers of conductors are connected with an LED on the source side and a photovoltaic cell on the output side. The electrical current flows from the source to the output side, but does not interact between the two sides. This effectively prevents arcing and sparks from forming between the two layers, as well as providing overall isolation between the two sides.

One of the most common optoisolator devices is the PC851XIJ000F. It is an optoisolator transistor with a photovoltaic output. It can be powered by either a 12V DC or 24V DC input voltage, providing flexibility in application. It is equipped with an LED, IC, and phototransistor to reliably transmit the electrical signal from the source side to the output side.

The PC851XIJ000F is primarily used in industrial operations as an isolation system and for transmitting digital signals. It is designed to be used in harsh environments, and its mechanical isolation system helps protect the target equipment from the high voltage system and harsh environment. It is also ideal for applications that need to exchange signals from machines or controllers, such as in Factory Automation Systems.

The PC851XIJ000F has a simple but effective working principle. The source side consists of an LED, which emits photons when a direct current is applied to it. The photons hit the phototransistor on the output side, and this generates a current. The current flows through the IC, and this controls the output. This working principle ensures that the electrical signal is transmitted reliably and can withstand voltage spikes and interference.

In conclusion, the PC851XIJ000F optoisolator is a reliable and efficient way to transfer electrical signals across two isolated circuits or components without inducing sparks or causing arcing. Its photovoltaic output and LED, IC, and phototransistor assembly make it a reliable and versatile optoisolator for industrial applications.
