Solid State Relays

Solid state relays (SSRs) are a type of electrical switching device that utilizes a semiconductor to perform switching operations within an electrical circuit. They are ideal for applications requiring high power level switching with no moving parts and minimal physical contact. One of the most common types of SSRs is the D2425G, which is a single-pole, double-throw (SPDT) device that operates off of a single phase AC voltage making it ideal for various AC load switching applications.

The D2425G contains a triac within its housing which acts as a semiconductor switch, providing complete isolation between the load and the input circuit. The triac is triggered by the application of a pulse of DC voltage to its gate electrodes. The gate voltage needs to be above a certain threshold for the triac to turn on, which is called the gate trigger voltage. When the triac is triggered, it is able to switch power to the load at the zero-crossing voltage of the input signal, eliminating arcing and losses that typically occur with conventional electromechanical relays.

The D2425G is typically employed in power switching applications that require a high power rating such as in motor control, lighting control circuits, industrial control systems and others. The device is especially useful in applications that require a rapid switching time (on the order of milliseconds) or precise timing with its built-in zero-crossing functionality.

The operating principle of the SPTD D2425G SSR is relatively simple and straightforward. An AC input signal is applied to the input terminals of the device. This AC voltage triggers the triac in the device and causes it to switch a DC or AC load connected to the output terminals of the SSR. The center terminal is the common point for both the input and output sides of the device.

When the input voltage is high enough to reach the gate trigger voltage, the triac turns on and allows current to pass through to the load. When the input voltage drops below the gate trigger voltage, the triac turns off and breaks the connection to the load. This switching action is controlled by the pulse of DC voltage applied to the gate electrodes of the triac, allowing the user to precisely control the switching of the load.

The D2425G SSR is a reliable and cost-effective device for controlling large AC and DC power loads. Its high-current rating and no moving parts make it well suited for industrial and commercial applications. The device’s built-in zero-crossing switch eliminates contact arcing losses and increases its reliability while the adjustable gate trigger voltage allows users to precisely control the switching of the load.
