Solid State Relays (SSRs) are considered an advanced type of mechanical switch, providing more advantages than traditional electromechanical relays. They are known for their flexibility, long life, low cost, and the ability to switch several times with much greater accuracy than other types of relays. The AQV201A is a type of SSR that has become popular for applications where precise switching is required without any noise or sparking. This article will discuss the application fields and technical components of the AQV201A, as well as how it works.

Application Field of AQV201A

The AQV201A SSR is designed primarily for use in industries or electrical applications where reliability, accuracy, and safety are essential. It is used in applications ranging from home appliances to industrial process controllers. It can be used to control AC or DC loads, such as motors, lights, heaters, contactors, solenoids, and more. The AQV201A can be used in applications where its environment is both rough and highly-accurate, such as robotic arms or medical equipment. It also has a wide operating temperature range and is capable of handling high load currents, making it suitable for use in industrial settings.

Technical Components

The AQV201A SSR works by utilizing a zero crossing detector and an SCR-based output. The zero crossing detector monitors the waveform of the AC power supply. When it detects a zero-crossing point, meaning that the waveform passes through zero volts, the SCR is triggered and the output turns on or off. This type of SSR is ideal for applications where precise timing of output switching is required, as the zero crossing detector ensures a reliable and accurate on/off switching of the output.

The AQV201A SSR is a four-terminal device, meaning it has two input/output terminals as well as two auxiliary contacts. These auxiliary contacts are used for safety shutoff, allowing the output to be shutdown in case of a fault or emergency. The AQV201A is also equipped with a surge suppressor, which helps protect the device from voltage spikes which can result from accidental mis-wiring, or in rare cases, from the power supply itself.

Working Principle

The AQV201A SSR utilizes both a zero crossing detector and an SCR-based output to switch power. When the data input is low, meaning the commanded output should be off, the zero crossing detector does not detect a zero-crossing point and the output remains off. When the input signal is high, meaning the commanded output should be on, the zero-crossing detector detects a zero-crossing point and triggers the SCR-based output. This triggers the output, either allowing or blocking current flow to the load. This process can be done multiple times, allowing the AQV201A SSR to accurately switch power on and off at precise times.

Conclusion

The AQV201A is an advanced solid state relay, offering precision timing and safety features for a wide range of industrial and electrical applications. It utilizes a zero crossing detector and SCR-based output to accurately trigger the output signal on/off multiple times. This allows it to be used in applications where reliability, accuracy, and safety are paramount.
