2.How to choose a thyristor optocoupler?

Thyristor optocoupler is a commonly used electronic component for signal transmission and isolation. When selecting, multiple factors need to be considered, such as linearity, isolation ability, working voltage, current, etc. According to the search results , the selection of thyristor optocouplers needs to consider the following aspects:

Linearity: The linearity of the thyristor optocoupler is an important factor affecting the accuracy of signal transmission. When selecting, it is necessary to ensure that the output characteristics and input characteristic curves of the optocoupler meet the requirements to ensure the linearity of signal transmission.

Isolation capability: The main function of the thyristor optocoupler is to isolate signal transmission and high-voltage circuits. When selecting, it is necessary to consider the isolation capability to ensure that the optocoupler can isolate the required signal and high-voltage circuit.

3.The working principle of silicon-controlled optocoupler?

Silicon-controlled optocoupler is a device that converts input optical signal into output electrical signal. Its basic components are photoelectric conversion devices and thyristor components. When the input optical signal irradiates on the photoelectric converter, the photoelectric converter converts the optical signal into electrical signal, and modulates and controls the output electrical signal through the silicon-controlled element.

4.Application fields of silicon controlled optocoupler?

1). Power control: silicon-controlled optocoupler can be used for AC and DC control, including AC dimming, DC Dimming, DC current control, AC contactor, reluctance thyristor and so on.

2). Electronic Circuit: SCR Optocoupler is widely used in various control circuits and switching circuits, such as time relay, switching power supply, inverter, DC power supply, inverter, etc.

3). Automatic Control: silicon-controlled optocoupler as a commonly used photoelectric isolation device, can be used in the field of automatic control signal isolation, security isolation, etc. , including PLC, frequency converter, discrete controller, automatic control device.
