FAQ
1.Darlington, what are the main functions of optocouplers?
Darlington Optocoupler is an electro-optical coupler that couples light to form an electro-optical and electro-optical converter. Its primary role is to isolate the field associated with the DC circuit and to provide high gain capability . In addition, Darlington coupler can also be used to control the sensitivity of transistors.
2.What products does Darlington optocoupler work on?
Darlington's output optocoupler has greater amplification power and faster speed than ordinary transistor output optocoupler. It is commonly used in industrial control applications for signal isolation and transmission . Darlington couplers are also used in situations where AC controls or switches are required.
What is the composition of the Darlington optocoupler?
Darlington optocoupler is a device that combines Darlington transistors and optocouplers. It is a device composed of a light-emitting diode, a photosensitive transistor, and a Darlington transistor.
4.What are the advantages of Darlington optocouplers over ordinary optocouplers?
Compared to ordinary transistor output optocouplers, Darlington transistor output optocouplers have stronger amplification ability and faster speed, which can be used to isolate high-voltage and low-voltage circuits, or to achieve functions such as photoelectric control.
5.What factors need to be considered in design?
As a driving element, the Darlington transistor converts the input signal into a driving output.
