Introduction

Optoisolators, also known as opto-couplers or opto-isolators, are electronic components that serve to isolate electrical signals from one circuit to another. The Optoisolator family includes Transistor, Photovoltaic Output, Photo-Darlington, Phototransistor Output, Phototriac Output, and Programmable Logic Controllers (PLC) Output. In this article, we will be focusing on the MOC215R1M, which is an optoisolator categorized as a transistor, photovoltaic output.

Applications

The MOC215R1M is mainly used in AC and DC industrial low-voltage motor control applications, including powering solenoids and controlling load breakers. In addition to motor control applications, MOC215R1M can be used in communications & networking, consumer & industrial transportation, and information technology & healthcare. It is composed of a photodiode, a phototransistor, a damping resistor, an LED, and a diode.

Working Principle

The MOC215R1M takes advantage of a photovoltaic effect in order to transfer information between two circuits electrically isolated from each other.The process begins with the input of a control signal from the other circuit into the MOC215R1M. This control signal causes the LED to produce light, which is then received by the photodiode housed in the transistor. Within the photodiode, the light triggers a current flow that changes the state of the phototransistor. This change in the phototransistor’s state creates an output signal, which can be used as an input source for the other circuit. The damping resistor which is designed to limit the emitted light and current flow at the photodiode, as well as the diode, ensures that the phototransistor is only triggered when a control signal is actively present.

Conclusion

The MOC215R1M optoisolator is an efficient and reliable device used to securely transfer information between two circuits that are electrically isolated from one another. This device utilizes the photovoltaic effect in order to achieve this purpose, making it suitable for motor control applications as well as communications & networking, consumer & industrial transportation, and information technology & healthcare. It is composed of an LED, photodiode, phototransistor, damping resistor, and diode, which work together to safely and reliably transmit information.
