Optoisolators – Logic Output is a form of electrical component that serves as an electrical interface between circuits. It is used mainly to carry voltage or current signals between two or more devices while completely isolating one of the circuits from the other. The H11N3SR2VM model is one of the more widely used optoisolator types nowadays, mainly because of its wide application fields and reliable working principle.

General Introduction to Optoisolator - Logic Output

The optoisolator, also known as an optocoupler, photocoupler, or optical isolator, is an electrical device which uses light, usually infrared light, to transfer electrical signals between two circuits. It is normally used to isolate sensitive circuits from other circuits, and it works by sending the electrical signal over the light from one circuit to the other circuit isolated from each other. The optoisolator can also convert a logic signal, such as a TTL level signal, to a logic signal of a different type, such as an isolated CMOS level signal.

H11N3SR2VM Model

The H11N3SR2VM model is a type of logic output optoisolator. This optoisolator has a GaAs (Gallium Arsenide) Infrared LED (Light Emitting Diode) as its input with a dual output Darlington pair for high-voltage switching. This optoisolator is suitable for applications such as power line switching, motor drive switching, and remote control switching. It has a maximum input/output voltage of 60V and a maximum input/output current of 500mA.

Application Field

The H11N3SR2VM optoisolator has various application fields. It is widely used for power line switching, such as in circuit boards, battery powered devices, and load switches. It can also be used for motor drive switching, for controlling inductive loads such as lights, motors, and solenoids. It can also be used for remote control switching, which is very useful in a variety of applications.

Working Principle

The H11N3SR2VM optoisolator works on the principle of isolating two circuits. The input circuit is connected to an infrared LED while the output circuit is connected to a dual output Darlington pair. When the input circuit is switched on, the LED emits a beam of light that is received by the output circuit. The output circuit then switches on, allowing the input circuit to control the output circuit without any electrical connection between the two circuits. This provides isolation between the two circuits, preventing any voltages or currents from flowing between them, thus protecting the input circuit from any damage caused by high voltage or current.

Conclusion

The H11N3SR2VM model is a logic output optoisolator that is widely used for power line switching, motor drive switching, and remote control switching. Its wide application fields and reliable working principle makes it an attractive choice for many projects. It works on the principle of isolating two circuits, providing an electrical interface between the two without any voltage or current flowing between them. This makes it a reliable and secure device for many applications.
