What are Solid State Relays?

Solid State Relays (SSR) are devices used to allow a load to be switched on or off by an automated or manual system. SSR’s use semiconductor components which do not require any physical contact or mechanical movement to switch and are therefore much more reliable and resistant to the elements.

D1D100 Application Field and Working Principle

D1D100 SSRs are most commonly used in industrial control applications and electronic/electrical circuit control projects, such as controlling relays for a wide range of industrial processes and controlling high voltage/current and voltage power. SSRs use FETs, TRIACs, thyristors or other semiconductor components which are inherently capacitive, such as silicon-controlled rectifier (SCR) or transistorized relays, to control switching on and off.

The switching device within an SSR is responsible for converting the incoming electrical current into a switching signal, i.e. it changes the electric current from an AC signal to a DC voltage or vice-versa. When the input voltage is applied, the voltage across the semiconductor is released and the relay will switch on or off a controlled device.

The general working principle of the D1D100 SSR is related to the electrical resistance of the controlled devices, which is controlled using the switching device by varying the overall electrical resistance. The varying resistance then controls the current passing through the SSR electrical circuit and this current in turn controls the switching device.

The signal input into the SSR can be from a low voltage/current device with a voltage of 12V (commonly used with automotive components) and up to 400V (for higher-powered industrial applications). The range of D1D100 SSRs varies and can be used in a wide range of applications.

The D1D100 SSR has a wide range of advantages over traditional relays. They are extremely reliable and low maintenance. They are also very fast acting and have a very rapid response time, making them ideal for automotive and industrial applications.

In addition, the D1D100 SSR is also designed to be compact and can be integrated into smaller systems. This makes them ideal for applications where size and weight are important considerations. Finally, SSRs have low power consumption, making them ideal for battery operated and mobile applications.
