DRA4-CMXE100D10 Solid State Relays

Solid state relays are electronic switching devices that use a signal-controlled semiconductor switch, instead of an electromechanical one. The DRA4-CMXE100D10 is a type of such relay, used in a variety of applications and with a working principle that is both straightforward and dependable. In this article, we\'ll discuss the application field and working principle of the DRA4-CMXE100D10 solid state relay.

Application Field

The DRA4-CMXE100D10 solid state relay is suitable for a variety of applications, from controlling pumps and motors to household appliances. Its design makes it ideal for applications where fast switching speeds are required, such as frequency converters, frequency inverters, and electronic part sorting systems. The DRA4-CMXE100D10 is also well-suited to applications that require high noise immunity, such as industrial automation and security systems.The DRA4-CMXE100D10 is available in an array of sizes and designs to suit different applications. The most commonly used size is the 4-pin version, which can be used to switch AC or DC currents up to 10A and voltages up to 250V AC or 30V DC. The unit can be used in ambient temperatures between -25 and 80°C, and is certified to IP67 protection level, making it durable in harsh environments.

Working Principle

The DRA4-CMXE100D10 solid state relay works on a principal of restistance-based switching. This switch type utilizes the temperature-dependent resistance of a semiconductor material (typically silicon) to control an electric current. A voltage is applied to the semiconductor to create a temperature gradient in which the resistance of the material in the area of the connection increases. This resistance increase limits the current flow through the circuit, thereby regulating the voltage on both sides of the switch. By controlling current and voltage in this way, the DRA4-CMXE100D10 can be used to switch various electrical components on or off.The DRA4-CMXE100D10 is designed to be switched by a DC control signal. The control voltage must be within the operating voltage range of the unit in order for it to work (approximately 4-10V DC). When the control voltage is applied, the resistance of the semiconductor increases, thus allowing the current to flow through the switch and causing the electrical components it is controlling to be turned on or off.

Conclusion

The DRA4-CMXE100D10 is a dependable and easy-to-use solid state relay that can be used in a variety of applications. Its resistance-based switching principle allows it to be controlled by a low-voltage DC signal, making it an ideal choice for switching a wide range of electrical components. In addition, its design makes it suitable for both household and industrial applications, as it is certified to a high IP protection level and can operate in a range of temperatures.
