Optoisolators are components that provide electrical isolation between two or more circuits. The CNW84 is a type of opto-coupler, which uses either a photovoltaic or transistor output in order to provide electrical isolation. This article will discuss the application field and working principle of the CNW84 opto-coupler.

CNW84 Application Field

The CNW84 is a versatile opto-coupler that has a variety of different uses. It can be used for AC or DC input signals, as well as both digital and analog signals. It is ideal for applications requiring electrical isolation, such as motor drives, industrial LED lighting, and any other application requiring an isolated input signal.

The CNW84 has a wide input voltage range, from 5 to 230VAC, 0 to 28V, making it suitable for a variety of different applications. Additionally, it has a wide temperature range, from -40 to + 70°C, making it suitable for use in extreme conditions. The CNW84 is therefore a suitable option for a variety of different applications.

CNW84 Working Principle

The CNW84 opto-coupler works by using either a photovoltaic or transistor output in order to provide electrical isolation. As input signals are received, the opto-coupler converts the input signal into a light output, which is received by a photosensitive element.

The photosensitive element then converts the light output from the opto-coupler into an electrical output which is sent to the output circuit. The output circuit is then able to respond to the electrical output, allowing for an isolated input signal to be present in the output circuit.

For photovoltaic output CNW84s, the photovoltaic element\'s resistance is varied depending on the amount of light it is exposed to. For transistor output CNW84s, the transistor\'s saturation region is controlled, allowing for varying amounts of current to be transmitted to the output circuit.

Conclusion

The CNW84 is a type of opto-coupler, which uses either a photovoltaic or transistor output in order to provide electrical isolation. It is a versatile device, with a wide input voltage range and wide temperature range, making it suitable for a variety of different applications. It works by converting an input signal into a light output, which is then converted by a photosensitive element into an electrical output that the output circuit can respond to.
