Solid State Relays

A solid state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied to its control terminals. It can easily and reliably control the on/off capability of varied load circuits and offers high isolation strength. A2402-10 is one of the popular SSRs used across a variety of fields due to its long life expectancy, low cost and versatility.

A2402-10 Application Field

A2402-10 SSR can be used across a wide spectrum of applications. Examples include:

• Heating & Cooling control: It can be used to control the temperature for all types of heating & cooling appliances like air conditioners, refrigerators etc.
• Lighting control: It can control illumination level, activate dimmer switches, phase control and time control for all types of lighting systems like street lights, ceiling lights, downlights, etc.
• Process control & Monitoring: SSRs are used when a critical process needs to be minimized and monitored repititively. It can be used for temperature control systems, or motion control systems in the industrial sector.
• Motor control: A2402-10 SSRs can be used to control and regulate the speed of motors as it offers precise control and flexibility.
• Security systems: It can be used in security systems likeclosed-circuit television and automation systems.
• Battery & Solar charging: A2402-10 SSRs can be used in battery and solar charging systems to ensure stable and safe charging.

A2402-10 Working Principle

A2402-10 SSR is an electrical switch that is operated by an electric current. It is a rail-to-rail limit comparing device that can diffently control the on and off states of a circuit. It uses the concept of thyristor principle of latching and triggering, which is its chief feature. As soon as the control current is applied to its control terminals, a small electric current passes through the gate of the latching thyristor and the connected load. This current powers the thyristor, creating a low resistance path between the two terminals, thus allowing the current to flow from one switch to the other.When the control current is removed, the contact between the two switches is broken and the load receives no power. This ensures safety and reliability. The A2402-10 SSR can be used for controlling both AC and DC loads of varied current ratings. The entire circuit is highly efficient and power saving.

Conclusion

A2402-10 SSR is a robust, feature-rich device that finds applications in a variety of fields, ranging from industrial control to home appliance control. It features high insulation levels, robustness and excellent power regulation efficacy. The built-in latching and triggering function ensures reliability and safety. The A2402-10 SSR is ideal for controlling and regulating AC and DC motor speeds and currents, lighting systems and a wide variety of industrial processes.
