CD2425E2URH

Solid State Relays

A solid state relay (SSR) is an electronic switching device that switches on or off when an external voltage is applied to its control terminals. Solid state relays are useful for applications ranging from small loads to large loads. They are also typically used in applications where the on/off control is powered by an external input, such as a temperature or pressure sensor.

The CD2425E2URH is a type of solid state relay, manufactured by CEL, with very low on-state resistance and a high load current rating of 25A. This relay is suitable for switching AC and DC load application and can be used in both low voltage and medium voltage applications. The relay is designed to have minimal power consumption and can handle ratings of up to 600VAC/VDC.

The CD2425E2URH works on the principle of direct-coupled MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) switching, where a MOSFET is used to control the switching of the load. The control terminal of the relay is electrically connected to the gate of the MOSFET. When the control voltage is applied, the MOSFET is then activated, thereby closing the circuit and allowing the current to flow through the relay.

When using the CD2425E2URH in medium voltage applications, it is important to be aware that the relay’s performance can be affected by various environmental factors such as thermal cycling, vibration, or exposure to high altitudes. It is also not recommended for use in applications that require high speed switching or require pulse width modulation.

The CD2425E2URH has many applications in industrial automation. It can be used in motor control, temperature control, lighting control systems, as well as in various other applications that require precise control of a load. This type of relay can also be used in applications that require a high load current, as it can handle ratings of up to 25A continuously.

In summary, the CD2425E2URH solid-state relay is a highly reliable and cost-effective relay with a wide range of applications in industrial automation. With its low on-state resistance and high load current rating, it is ideal for switching AC and DC load applications, both in low voltage and medium voltage applications.
