Solid State Relays (SSR) are used to control electrical loads by switching the power with no moving parts. They are based on semiconductor technology and have been found to be reliable and efficient in numerous applications. CD4825W4U is a Digital Input Output 4-Channel Solid State Relay from Carlo Gavazzi that can be used to control various device and machine applications for controlling the power through a digital input signal.

The CD4825W4U comes with a 4A current carrying capacity and a minimum on-state resistance of a mere 8 mΩ. It runs on a 24VDC voltage, with an input voltage range from 4V to 30V, and an insulation voltage of 250V. The CD4825W4U is a compact and efficient device, designed for use in industrial control applications. It is rated for up to 1,000,000 operations and is capable of operating in temperatures ranging from -25°C to +75°C.

The CD4825W4U is a solid-state relay that allows users to control the output of an external DC voltage, typically between 0 and 24V, using a 4-channel (4-bit) digital output signal. It can also be used for controlling AC power devices. The relay is capable of switching loads, up to 4A, at the input signal. It is an optically-coupled SSR, meaning that it uses a phototransistor to isolate the control signal from the power it is controlling.

The working principle of the CD4825W4U is fairly simple. A digital input signal, from an external device such as a microcontroller, is sent to the relay. The microcontroller can output a 4-bit signal, depending on the load to be controlled by the relay. This signal is then sent to the phototransistor inside the relay which then controls the power load it is connected to. The relay is capable of carrying up to 4A, allowing it to control a wide range of loads.

The CD4825W4U is an optically-coupled solid state relay designed for use in a wide range of industrial, consumer and medical equipment applications. It is capable of controlling loads up to 4A and can be used to control numerous devices and machines. It features a 4-channel digital input and output and is rated for up to 1,000,000 operations. It is designed to operate in temperatures ranging from -25°C to +75°C, making it an ideal device for a variety of application fields.
