Optoisolators, also known as optocouplers, are optoelectronic devices used to keep two separate circuits isolated while allowing them to communicate. Optoisolators are widely used in applications ranging from low power audio signal isolation to high-voltage power systems. One example of an optoisolator is the MOC81023S, a type of Transistor, Photovoltaic Output optoisolator, that is often used in industry applications. This article will discuss the application field and working principle of the MOC81023S optoisolator.

The MOC81023S is a 6-Pin dual-channel optoisolator with integrated 5V/50mA logic drivers. This optocoupler has a reliable and robust design for industrial applications and is RoHS compliant. The MOC81023S has a low input current (2.5mA max) and can provide high speed and high efficiency current switching in industrial environments. The output of the MOC81023S is a photo-voltage which is used to provide a DC isolation barrier between two circuits.

The MOC81023S is typically used in industrial control applications such as stepper motor and DC motor driving and control, industrial automation, power supply controls, robotic controls, and process control. It can also be used in industrial applications such as frequency meter or power meter, solar panel controller, and level-setting or pressure monitoring systems. In addition, the optoisolator can also be used in transportation applications for control of actuators such as the throttle control, speed control, and brake systems. The MOC81023S is a versatile optoisolator that can be used in a variety of applications throughout many industries.

The working principle for the MOC81023S is quite simple. The optoisolator consists of a light source, such as an LED, and a phototransistor. When a voltage is applied to the LED, it emits light which is detected by the phototransistor. This triggers the transistor to conduct current, creating an output voltage. The optical isolation provided by the device keeps the two circuits electrically isolated from each other. It also prevents current, voltage, and electric noise from being transferred between the two circuits. Thus the optoisolator can be used to provide signal transmission between two circuits without allowing any electricity to be transferred.

In conclusion, the MOC81023S optoisolator is a versatile optoelectronic device that can be used for many different industrial and transportation applications. It provides a high-speed and high-efficiency current switching solution for industrial environments. The optoisolator has a reliable and robust design as well as a low input current, making it ideal for many types of applications. Its working principle is based on the use of an LED and a phototransistor to provide optical isolation between two circuits, which prevents current, voltage, and electric noise from being transferred between the two circuits.
