Solid State Relays (SSR) are a type of electrical relay that use a semiconductor instead of a mechanical armature to make or break a connection. They are widely used in robotics, automation and process control systems. The CKRD4810-10 is one of the most popular types of SSRs for industrial control applications. This article looks at the application field and working principle of the CKRD4810-10.

Application Field of the CKRD4810-10

The CKRD4810-10 is a three-phase SSR designed for switching operations in industrial control systems. Its main application field is AC load switching. This means it can be used to control a wide range of motorized equipment, from small electrical pumps to large industrial HVAC and electrical motors. It can also be used to switch DC loads such as solenoids and DC motors.

The CKRD4810-10 is rated for current up to 10A and has a maximum voltage of 600V. It is suitable for a wide variety of industrial control applications, such as machine tools, welding machines, elevators, motors, compressors, etc.

Working Principle of the CKRD4810-10

The CKRD4810-10 consists of a three-phase AC solid state relay, a control module and a DC power supply. The relay is triggered by a low voltage DC signal from the control module. This signal triggers the internal MOSFETs, which in turn close the contactors of the AC switches.The CKRD4810-10 uses a Zero-Crossing Technology that ensures reliable switching of the SSR and prevents electrical noise caused by the switching process. The SSR also has several failsafe features that prevent unintentional switching.The control module of the CKRD4810-10 can be used to set two adjustable parameters: the minimum and maximum switching time. The minimum switching time can be adjusted from 0.2 to 2 seconds, and the maximum from 3 to 15 seconds. This allows the user to set the optimal switching time for each application.

Conclusion

The CKRD4810-10 is a popular SSR used in a variety of industrial control applications. It is rated for currents up to 10A and voltages up to 600V, and is equipped with several features that help ensure reliable switching and prevent unintentional switching. The control module also allows the user to set adjustable parameters, such as the minimum and maximum switching times.
