Power Relays, Over 2 Amps

Introduction to 2821258

2821258 is a type of power relay, most commonly used for current levels above 2 amperes. Power relays are electromechanical elements used to transfer electric load from a control circuit to a commanded circuit. This power relay has many applications such as switching lamps, controlling motors and assisting in circuit protection.

Design of 2821258

2821258 is constructed by using a magnetic slug core, armature, solenoid coils, contact points, an armature arm and a base. The base is made from corrosion resistant materials which ensure the stability of the power relay. Magnetic slug core helps to transfer electric impulses. Armature arm is connected to an external circuit. A small current is passed through the external coil when it is connected to the power supply. As a result, the armature arm is drawn towards the core due to magnetic attraction and it pushes the contact points, to make a connection between the two circuits.

Working Principle of 2821258

The working principle of 2821258 is based upon the principles of electromagnetism. It is an electromagnetic device used for controlling the flow of power to other circuits. This power relay can be easily operated using a control signal from an external source. When a control signal is applied, the armature arm moves towards the core, compressing the spring between the armature arm and the contact points. This action causes a contact point to close, thereby creating a connection between the two circuits.

Additionally, 2821258 can be wired in various configurations, such as Normally Open (NO), Normally Closed (NC) and Change-Over (CO). In Normally Open configuration, two contact points are placed in an open position, whereas in the Normally Closed configuration; the contact points are placed in a closed position. With Change over configuration, the contact points can be connected in series or parallel with each other.

Applications of 2821258

2821258 is a very versatile power relay and has many applications. It can be used in a variety of circuit protection systems, such as overvoltage protection, undervoltage protection, and surge protection. Furthermore, 2821258 can be used to switch lamps and electrical motors, and it is also used in automation and control systems.

2821258 can also be used for low power applications such as signal processing and data acquisition. It is also used in industrial applications, such as controlling the operation of pump motors, safety systems, and security systems. Moreover, 2821258 is widely used in automotive applications as it is reliable, robust and easy to use.

Conclusion

2821258 is a versatile power relay that is used to transfer electric load from a control circuit to a commanded circuit. It is reliable, robust and easy to use, with a variety of applications from data acquisition to motor control. 2821258 is also used in circuit protection systems, such as overvoltage protection, surge protection, and undervoltage protection.
