Solid State Relay AQY212EHAZ

AQY212EHAZ is a solid-state relay (SSR) that provides all the advantages of solid state switching without the burden of complex alternative technologies. It is designed and manufactured by Omron Automation and Safety, a global manufacturer of automated control products. This relay comes in a single-pole double-throw (SPDT) configuration, and it can handle 10A of continuous load current at up to 250VAC. It is ideal for applications such as HVAC systems, electric motors, mechanical equipment, and other processes that require load switching.

Application Field

The AQY212EHAZ is designed for use in industrial and commercial settings where a reliable, cost-effective solid state relay is required. Some of the most common applications where it is used include:

• HVAC systems
• Controlling electric motors
• Mechanical equipment
• Temperature controllers
• Lighting systems
• Heating elements
• Industrial processes

The AQY212EHAZ is also compatible with PLCs and other devices that require low-amperage switching. This makes it an ideal choice for applications that need to control large loads with a small amount of power.

Working Principle

AQY212EHAZ relays operate on a principle called "Zero-Crossing Switching." This means that the relay does not turn on or off until after the supply voltage has gone through a zero-volt point. This design has a couple advantages. First, it eliminates any inrush current that is associated with switching a load. Second, it avoids any over- or under-voltage conditions that can occur when switching large loads. When the relay is powered on, the internal circuitry begins monitoring the input voltage. When the voltage passes through the zero-volt point, the relay triggers and the load is switched. When the voltage drops back down through a zero-volt point, the relay will trigger again and the load will be switched back off. The AQY212EHAZ relay is rated for up to 10A of continuous load current, with a maximum peak of 16A. It will operate in both AC and DC circuits and has a minimum supply voltage rating of 22VAC. It also includes over-/under-voltage, over-temperature, and surge protection features to ensure safe and reliable operation.

Conclusion

The AQY212EHAZ relay is an excellent choice for applications that require reliable, cost-effective switching of up to 10A of continuous load current at up to 250VAC. Its Zero-Crossing Switching design ensures safe and reliable operation in both AC and DC circuits, while its over-/under-voltage, over-temperature, and surge protection features provide further protection against electrical hazards. This makes the AQY212EHAZ relay an ideal choice for industrial and commercial applications that require a reliable and cost-effective solid state switching solution.
