Introduction

AQY216EHAZ, also known as an “AC Solid State Relay”, is an electrical device that uses power semiconductor devices, usually transistors, instead of mechanical contacts to control the switching of an electric load. The device is often used as a replacement for mechanical relays that use contacts to control the on and off of electrical circuits. It can be used in applications that involve high-frequency switching that requires a fast and precise control.

Application Fields

AQY216EHAZ solid-state relays are widely used in a variety of applications, including air conditioner, home appliance, automotive and industrial control, and others. As a result, they are suitable for controlling a variety of loads, such as resistance, capacitive, inductive, and lighting loads, as well as AC and DC motors.AQY216EHAZ has a wide input range of AC voltage and can handle various voltage levels, such as 110V, 120V, 220V and more. It also has a wide operating temperature range of -40°C to +85°C, which makes it suitable for use in environments with extreme temperatures. In addition, its high surge current absorption provides a high level of protection against surges and ensures reliable operation of the circuit.

Working Principle

When a voltage is applied to the AQY216EHAZ solid-state relay, the relay switches the load between two states, which are typically open and closed. This switching is done by using a power semiconductor, such as a transistor, that is controlled by the relay’s input signal. The input signal is used to switch the transistor either on or off. When the transistor is on, the relay closes the load and when it is off, the relay opens the load. The speed of the switching process depends on the power semiconductor device and other parameters.The AQY216EHAZ solid-state relay is designed with two optical isolators that provide safety and prevent any interference between the load switching circuitry and the control circuit. The two optical isolators are used to separate the load switching circuit from the input control circuit. This provides isolation between the two circuits and prevents any interference between the two. AQY216EHAZ also includes an operational amplifier with a latch configuration to change the state of the load without the need to manually reset the switches.

Conclusion

AQY216EHAZ solid-state relays are reliable, efficient and versatile devices for controlling a variety of loads. They are designed to switch between the open and closed state at high speed and with a precise control. They also feature wide input voltage levels, as well as wide operating temperature ranges, and good surge current absorption. In addition, the two optical isolators make the AQY216EHAZ suitable for applications that require isolation between the load switching circuit and the input control circuit.
