DR24E03X is a type of solid state relay (SSR) that is used for controlling and switching loads of power circuits in an automatic machine or system. It is widely used in industrial automation and electronic equipment. DR24E03X offers reliable control performance, long switching life and vibration/shock resistance. It is also designed for easy installation and maintenance.

The DR24E03X is a high-efficiency SSR that has a compact footprint. It consists of a thermally conductive heat sink base, a cover, a zero-crossing optical-coupled input, an LED driver circuit, and two solid-state switching elements. The input can be triggered from a variety of sources, including the synchronization signal from a PLC or process controller, a mechanical switch, or a voltage signal from an instrument.

The DR24E03X is designed with integrated zero-crossing technology, which helps to provide better control of switching frequency. This reduces EMC problems and ensures the power supply is always in ‘on’ state, which improves system safety. As a result, the DR24E03X is particularly suitable for pulse-width-modulated (PWM) speed control applications.

The working principle of the DR24E03X is based on the use of dimmable LEDs that are optically coupled to a magnetic core switch. When the magnetic core is closed, current is passed through the LED and it emits light that switches the two solid-state switching elements. This creates a low resistance between the load and the power supply, allowing the current to flow. When the magnetic core is open, the LED is no longer able to emit light and power cannot flow between the load and power supply.

The DR24E03X is capable of controlling AC/DC loads of up to 480 V, with a switching frequency of up to 1000 Hz. It is equipped with over-current protection, short-circuit protection, and over-temperature protection to ensure safe and reliable switching and control. In addition, the DR24E03X is designed with self-diagnostics to detect various kinds of abnormal operation, making it an ideal choice for industrial control systems.

The DR24E03X is an indispensable part of industrial automation. It can be used in a variety of applications, such as electric heating, food processing, safety operations, and mechanical control. Its high-efficiency and reliable control performance make it a valuable component in any automation system.
