Power Relays, Over 2 Amps

The ALE74B06 is a powerful reed relay designed for applications that require switching currents of more than 2 amperes. It is capable of switching DC and AC voltages up to 250V. It is designed to be integrated into electrical apparatus control systems where a heavy duty power relay is needed.

Basic Construction

The ALE74B06 relay is constructed from high quality materials to ensure durability. It has two power terminals, one for the supply side and one for the load side, and two control terminals, which are commonly referred to as the "common" and "normally open" terminals. The body of the relay is constructed of an epoxy resin to ensure that it is corrosion-resistant and able to withstand high temperatures.

Working Principle

The ALE74B06 works on the principle of induced current. When power is applied to the supply side of the relay, an electric field is created within the coil surrounding the reed. By adjusting the current to the coil, the strength of the magnetic field created within the coil can be modified, resulting in the reed opening or closing depending on the strength of the magnetic field.Once the magnetic field is adjusted, the reed will open or close depending on the strength of the magnetic field. As the reed closes, it connects the two power terminals, allowing current to flow between them. This will activate the circuit and the load can be switched on or off as desired.

Applications

The ALE74B06 is typically used as a control relay in electrical control systems. Due to its high power handling capability, it is often used in high load applications such as motors, pumps, and air conditioning units. It is also ideal for controlling higher voltage applications such as home wiring, industrial lighting, and refrigeration.The ALE74B06 is also commonly used for its quick response times. It is capable of switching off at a fraction of a second and is therefore ideal for applications which require instantaneous response times, such as time-delayed circuits.

Special Features

The ALE74B06 also features an air gap that provides an additional degree of protection from over currents. This air gap will automatically open in the event of an overload, allowing the current to be disconnected from the load. This feature ensures that the relay does not get damaged in the event of an overload.

Conclusion

The ALE74B06 relay is an extremely versatile and powerful reed relay suitable for controlling higher voltage applications and high load applications. Its quick response time and air gap feature make the ALE74B06 ideal for use in high-current applications in industrial, commercial, and residential settings.
