CD2425E1U is a type of Solid State Relay (SSR). It is a type of electronic switch device that remains off until a triggering voltage is applied. Unlike mechanical relays, which contain an actuator such as a coil and contact that must physically move when the load is switched, solid state relays merely activate when their trigger voltage is applied, and consequently have much faster switching speeds than traditional mechanical relays while also consuming much less power. They are commonly used in industrial automation processes for the control of motors, pumps, valves, and any other type of electrical load.

CD2425E1U is a zero-crossing SSR that can switch AC loads up to 25A at 240VAC and has a wide operating temperature range of -20°C to +80°C. The zero crossing feature ensures that the SSR switches on and off at the zero crossing point of the supply voltage, reducing noise and inrush current and improving the life of the load. The device also includes a soft start feature, which slowly ramps up the output from 0% to a steady 100%, preventing large current inrush and reducing power supply stress. The SSR has a hot switching capability of up to 10 times per minute, making it ideal for use in applications that require frequent switching.

The CD2425E1U is particularly suitable for controlling motors, pumps, valves, solar heating, and other switching applications. It offers superior performance in terms of speed, accuracy, power savings, and long life. Thanks to its compact size and wide operating temperature range, the device can be easily mounted in control panels or on PCBs for many high-performance switching applications.

To activate the CD2425E1U, a trigger voltage is applied to its control terminals. This triggers its internal semiconductor switching mechanism, which allows a voltage to flow through to the load. The trigger voltage can range from 5 to 28V DC, and the SSR requires a minimal 15mA current for operation. The trigger voltage can be switched on and off using either a transistor or a logic input, such as a microcontroller, enabling control over the switching behavior of the SSR.

In addition, the CD2425E1U includes overvoltage, overcurrent, short-circuit, and thermal protection features to protect the device against damage and a robust dielectric strength of 4kV to help ensure a safe operation in many industrial applications. Furthermore, the SSR uses high-efficiency electronics and is RoHS compliant, helping to meet environmental protection standards. It is also UL508 certified and CSA 22.2 certified, making it safe to use in many industrial applications.

All in all, the CD2425E1U is a highly reliable high-performance electronic switch device for industrial automation applications. It is a great choice for controlling motors, pumps, and valves. Thanks to its zero crossing feature, soft start, and overvoltage, overcurrent, short-circuit, and thermal protection features, the CD2425E1U is an excellent choice for safety critical applications.
