PS2514L-1Y-F3-A Datasheet/PDFOptoisolators are electrical components that provide electrical and optical isolation between two electric components or circuits. In some cases, optical isolation can reduce the chances of interference or damage caused by electromagnetic radiation. The PS2514L-1Y-F3-A is an example of an optoisolator that combines a photovoltaic output (PV) with a transistor.
The PS2514L-1Y-F3-A optoisolator consists of an infrared LED, a photovoltaic isolator, and a transistor output stage. The LED emits an infrared light which is detected by the photovoltaic isolaotr. This converts the light into an electrical signal which is then used to control the transistor output stage. The device has a low on-state voltage of 2.5V and a maximum operating current of 500mA.
Application Fields
The PS2514L-1Y-F3-A optoisolator can be used in a variety of application fields. It is commonly used as an interface for sensors and switches which require electrical isolation and which are not capable of direct connection to a digital circuit. It is also used as an interface between high-voltage/high-current circuits and digital circuits which require electrical noise isolation. The device has been used in a range of industrial applications such as motor and power supply control, HVAC systems, and factory automation.
Working Principle
The working principle of the PS2514L-1Y-F3-A optoisolator is based on the principle of photovoltaic isolation. The infrared LED emits light which is detected by the PV isolator. This produces a voltage proportional to the intensity of the light. This voltage is then used to turn on the transistor output stage. When the transistor is activated, it switches current between the power (high voltage/high current) and the output (low voltage/low current) circuits. In this way, the optoisolator provides electrical and optical isolation between the two circuits.
Conclusion
The PS2514L-1Y-F3-A optoisolator is a useful component for providing electrical and optical isolation between two electric components or circuits. It is commonly used in a variety of applications, including motor and power supply control, HVAC systems, and factory automation. The device operates on the principle of photovoltaic isolation, in which an infrared LED is used to produce a voltage which is used to turn on the transistor output stage. This switches current between the power and output circuits, allowing for electrical and optical isolation.
