This force will be almost equal to half the strength of the magnetic force. Relay Working. Thus the switch plays an important role in the relay working. CircuitsToday.com is an effort to provide free resources on electronics for electronic students and hobbyists. The most common type of relay used in automotive applications is the single pole/double throw . They played an important role in switching calls in telephone exchanges. Requests to customers (Dedicated to industrial motors). Relays are used to control high voltage circuits with the help of low voltage signals. The definition is: Activating the contact unit using electromagnetic attraction, which is produced when electric current exceeding the specified value flows to the electromagnet; the voltage and current (input signal) applied to the coil opens or shuts the contact. There are also other operating principles for its working. Also, the design, construction, working, applications, and also relay selection is explained in detail. As it is a part of the load circuit, it is used to control an electrical circuit that is connected to it. There are only four main parts in a relay.

Relays are also named with designations like. very informative and explanations made very easy to understand. The application of relays started during the invention of telephones. They play a very important role in providing safety critical logic. Requests to customers (Automation Control Components & Industrial Device) [For specific product] good…it really helpful for me…nice explanation, which books can i get this informations about relay, it is used for when ever fault will be accured in ckt relay isolated and protect the devices, I want explanation with all diagrams and with colour coding. Thus, when the electrical relay in energized the current flow will be through the pins 2 and 4. not appropriate info. A Relay comprises of an electromagnet and a contact unit. I have liked the work because explains everything about relay. Really useful Definitions should be given. (PhotoMOS/SSR (Solid State Relays)). Need more detailed diagrams. This strip is set to make contact with a contactor by bending itself with rising temperatures due to excess current flow. Ratings – There are current as well as voltage ratings. Although there are various relay designs, the ones most commonly found in low voltage auto and marine applications are electro-mechanical relays that work by activating an electromagnet to pull a set of contacts to make or break a circuit. Each pole has contacts that can be thrown in mainly three ways. Business

plz to be explian AUTORECLOSED TIME HOW TO OPERATEDED relay? A switch is connected to the load. Coil protection helps in reducing surge voltage produced during switching. ­­A relay is a simple electromechanical switch made up of an electromagnet and a set of contacts. The most widely used overload relay is the thermal overload relay where a bimetallic strip is used to turn off the motor.

Also known as the Bosch relay, the SPDT has a common, movable contact that moves between two fixed contacts, termed Normally Open and Normally Closed. A relay is used in various pieces of equipment in the world. They are. Requests to customers (FA Sensors & Components [Excluding motors]) All overload relays available to buy comes in different specifications, the most important of them being the current ranges and response time. What is a relay? In case of voltage ratings, they vary from 300 Volt AC to 600 Volt AC. Type of contact used – Whether it is a NC or NO or closed contact. > Introduction to Relays - What are Relays? They are used to time the delay open and delay close of contacts. you could use a diode for protection though(protection diode), very basic but important info..thanx alot. They are also used as protective relays. One is low voltage application and the other is high voltage. In fact, some of the first computers ever built used relays to implement Boolean gates.. They are, good,but diagram is helpfull to understand easily. You consent to our cookies if you continue to use our website. By this function all the faults during transmission and reception can be detected and isolated. Most of the devices have the application of relays. is given it has to be elaborated with design diagram……….. thank you very much for the useful information .
