Solid-state relays (SSRs) are electro-mechanical devices that use a solid-state circuit to switch electrical signals. They are an alternative to traditional electromechanical relays and are often used in applications where low-power switching, low-voltage operation, and high reliability are required. CD4825E4VRH is a type of solid-state relay with these and other features.

CD4825E4VRH is characterized by a load current up to 25 Amps at 250VAC, a control voltage at 4-32VDC, and an operating frequency of 50-60 Hz. It has a zero voltage turn-on and on-off delay characteristics, dielectric strength lx500VAC(50/60Hz 1min) and power loss is less than or equal to 1.5 W. The SSR has a must response current at 50mA-30KHz, and its insulation resistance is greater than or equal to 100mOhm at 500 VDC.

CD4825E4VRH is widely used for controlling high-power loads in many kinds of applications, such as electric power, refrigerators, air-conditioners, copiers, toys and program-controlled telephone switching systems. Since it is a zero-voltage triggered device, it can be used to protect overload circuits in both AC and DC modes and to switch between different voltages and frequency.

The operating principle of CD4825E4VRH is divided into three stages: input control, power control, and output control. In the first stage, the SSR is operated by controlling the current or voltage in the input terminal to control the ON or OFF state of the device. The input control determines the output status of the SSR. In the second stage, the input command is converted into the corresponding output power, responsible for controlling the load current. Finally, the SSR will output a signal to control the load and complete the entire switching process.

CD4825E4VRH is a multi-functional and reliable solid-state relay with high performance. Its diverse applications and circuit-controlled design make it popular for many industries. With its simple switching control and high accuracy, the SSR offers users robust performance, long life, and consistent reliability.
