    Relay

    A relay is an electronically operated switch that is remotely activated by an electromagnet which pulls a set of contacts to either make or break a circuit. Electrical relays are commonly used for switching signals, radio frequencies, high current circuits when using a lower current circuit, and loads such as resistive, motor, lamp, inductive, and capacitive applications. This is helpful when an in-line switch or existing circuit does not have the capacity to handle the required current.

    Functions of Relays

    Galvanic separation of the primary or actuating circuit and load circuits
    Single-input/multiple-output capability
    Separation of different load circuits for multi-pole relays
    Separation of AC and DC circuits
    Interface between electronic and power circuits

    Relays have the same subsystems and principles of operation regardless of whether these are electromechanical relays or electronic relays or designed to switch signal or high-power loads. Relays convert an electrical input signal on the primary side to an intermediate and non-electric physical signal. These devices also reconvert the non-electric physical signal to operate a switching element (secondary side) such as contacts which switch and conduct electrical current (i.e., output, load current). Relays use the non-electric signal between the primary and secondary side to provide the necessary galvanic separation between the input and output circuits. Relays enable a single output that can activate multiple circuits and functions, which helps increase cost savings because high current capacity switches cost more than lower current versions. Relays can also perform logic functions on certain inputs, such as latching an output on and off from a momentary input. When a switch cannot take a high current or is operated by electronic circuit, the relay can be operated by switch circuits. 

    Relays have a number of basic parts that form the relay.

    A coil wound round an iron core to increase the magnetic attraction is needed. The coil of wire causes an electromagnetic field to be created when the current is switched on an causes the armature to be attracted. 

    A mechanical frame is required to hold the components in place. This frame is normally quite robust so that it can firmly support the additional elements of the electromechanical relay without relative movement. 

    This is the moving part of the relay. This element of the relay opens and closes the contacts and it has a ferromagnetic metal to be attracted by the electromagnet. The assembly has an attached spring which returns the armature to its original position.

    The contacts are operated by the action of the armature movement. Some of the electrical switching contacts may close the circuit when the relay is activated where as others may open a circuit. These are known as normally open and normally closed.
