Solid State Relays

Solid state relays (SSRs) are electronic switching devices that are used to switch AC or DC loads. Unlike their mechanical counterparts, which use physical contacts to make and break electrical connections, SSRs use semiconductor switching technology. This technology provides higher electrical isolation between the input and output, and eliminates the need for contact wear or tracking.

G3HD-202SN DC12-24V is a type of solid state relay that allows a controlling circuit to switch only one load at a time based on the type of application. This has been largely designed and manufactured by Autonics, and is considered as one of the leading products in the SSR market.

Application Field
Since the output power source of G3HD-202SN DC12-24V is a DC current, the SSR is mostly used in DC motor control, contactors, and solenoids. It is also used in industrial equipment, such as battery chargers, medical equipment, filter controllers, and electrical time protectors. This product is also suitable for assembly line machines, as well as factory operations where safety of the workers is of the utmost importance.

Working Principle
The G3HD-202SN DC12-24V works on the principle of semiconductor switching. The relay includes a small semiconductor switching element, such as an integrated circuit, that is driven by the input signal from the controlling circuit. When the input signal is applied, the semiconductor switch turns on and the output signal is applied to the controlled load to turn it on or off. The switch is then turned off when the input signal is removed.

This type of SSR also includes a number of safety features that help protect the user from any potential hazards caused by electrical shocks. The relay\'s built-in over-temperature protection function automatically reduces the output current if the temperature reaches a certain threshold. Additionally, the SSR includes protection against surge voltages and transient currents to protect against instant surges in power. The relay also features reverse-polarity protection, which prevents any damage to the SSR if the power supply polarity is inadvertently reversed.

The G3HD-202SN DC12-24V has been designed with high performance and reliability in mind. It offers a long life expectancy, minimized maintenance costs, and is designed to work reliably in harsh conditions. It comes with an IP67 shock and vibration-proof rating, which makes it suitable for use in a wide range of applications.

Overall, G3HD-202SN DC12-24V is an ideal choice for industrial applications that require reliable performance and compatibility with DC power sources. It offers high electrical isolation, safety features, and is designed to work in harsh environmental conditions. The SSR is also relatively easy to use and maintain, making it a popular choice for many applications.
