Solid State Relays (SSRs) are specialized devices that incorporate semiconductor aspects for their primary working principle in order to switch electrical circuits without relying on moving parts. Unlike traditional electromechanical relays, SSRs require only tiny amounts of current and voltage or a single digital input to turn on and off their load. As such, they are used heavily in a variety of types of industrial applications.The AQW215 series of solid state relays are powerful devices that are designed to be subjected to severe industrial use. These solid state relays provide a higher degree of electrical isolation between the input and output circuits, which helps to reduce common-mode interference. The AQW215 series is rated up to 16A at 400Vrms, making them suitable for a variety of industrial applications.The mechanism of an AQW215 solid state relay consists of an opto-isolator and a solid-state switch. The opto-isolator typically consists of a light-emitting diode (LED) and a photodiode. When an input voltage is applied, the LED light is turned on and the photodiode senses the light and allows current to pass. This current then passes through the solid-state switch, which is usually a MOSFET, thereby closing the circuit and activating the load.The main advantage of AQW215 series of solid state relays is their fast response time, superior reliability and low power consumption. This makes them the ideal choice for applications where reliability and speed are of the essence. Typical applications of AQW215 series relays include motor control, switching contactors, PLCs, temperature controllers, HVAC systems, liquid level sensing and flow metering, and so on.Due to their versatile nature and high degree of electrical isolation, solid state relays are also used for a variety of sensitive and delicate applications. Some of these applications include medical imaging, electrical safety systems, and even aerospace applications.The high switch-on and switch-off speeds of AQW215 series relays make them suitable for EMC/EMI sensitive applications. They also offer a high degree of reusability, making them ideal for applications that require frequent maintenance and repairs.The AQW215 series of solid state relays also come with built-in protection features such as reverse voltage protection, overvoltage protection, undervoltage protection, overcurrent protection and surge protection. This helps to ensure reliable and safe operation of the device.Overall, the AQW215 series of solid state relays are reliable and powerful devices that can be used in a variety of industrial applications. These devices offer superior electrical isolation, fast response time, low power consumption, and built-in protection features, making them ideal for a wide range of applications.
