They are used where it is necessary to control a circuit by a separate low-power signal, and perfect for use in an internet connected applications. Wholesale TE Connectivity Relays Distributors also have a wide range of other engineered electronic components such as connectors, terminals, sensors and many more. The first relays were used as amplifiers in long distance telegraph circuits where they repeated the signal coming from one circuit and retransmitted it to another circuit. They were used in the telephone exchange and early computers to perform logical operations.

The home of the future is here and the wholesale TE connectivity relays distributors provide a wide range of relays for your domestic electrical system for protection of equipment and also for the protection of the operator. Fuse, MCB, ELCB (Earth leakage circuit breaker) etc they immediately turned off automatically in case of any abnormality in the equipment.

When it comes to larger power consumption such as in industry for the protection of the system and equipment’s then we have to rely on the relay. In the industrial systems, the electrical circuit consists of two parts: Power circuit and control circuit. A power circuit provides a significant electrical capacity to operate something that does a lot of work, such as high power heaters or multi-horsepower motors.

Power circuit deals with the flow of the 3 phase/1 phase 50 Hz power, whereas the control circuit deals with the switching (On/Off) and protection system of the equipment.

A relay is located in the control circuit. A control circuit is a lower, single phase power line that could also be low as 24 V that provides a much lower level of power to operate control logic. The relay does not have contact; they sense the current and voltage in the power circuit through the current transformer (CT) and potential transformer (PT). A relay will generate a trip command by breaking its contact through the control circuit and will trip, in case the value of the current, frequency, voltage or power crosses a particular limit.

Different types of relay: An electromagnetic relay is a type of magnetic switch which operates on the principle of electromagnetic attraction. It uses the magnet for creating a magnetic field, the magnetic field then uses for opening and closing the switch. Based on the working principle, the electromagnetic relay is classified into two types. These are 1.

Electromagnetic Attraction Relay

2.

Electromagnetic Induction Relay

Other than the electromagnetic relay there are many other types of relays which differ based on the principle of operation and polarity.

Based on the principle of operation:  Electro thermal relay A bimetallic strip is made by joining two different materials, this strip is tending to bend when it gets energized and this bending nature makes a connection with the contacts.  Electromechanical relay Based on the property of an electromagnet and few mechanical parts a connection is made with the contacts.  Solid state relay As compared to other relays, the main advantages of this relay are its more lifespan and faster switching operation. Solid state relay uses semiconductor devices. Therefore, the switching speed of the device can be made easier and faster  Hybrid relay When electromechanical and solid state relays combine it works as a hybrid relay Based on the polarity:  Polarized relay In a Polarized relay, the movement of the armature depends on the polarity of the input signal applied to the coil. These are similar to the electromechanical relays and generally used in telegraphy applications.  Non-polarized relay In non-polarized relay, the movement of the armature or its operation remains unchanged even if the polarity of the input signal is altered since the coil in these relays doesn’t have any polarities.
