What are the different types of relay?
There are different types of relays like:
- Electromagnetic Relays.
- Latching Relays.
- Electronic Relays.
- Non-Latching Relays.
- Reed Relays.
- High-Voltage Relays.
- Small Signal Relays.
- Time Delay Relays.
What is a relay and how it works explain the various types and applications of the relay?
So relay is a switch which controls (open and close) circuits electromechanically. The main operation of this device is to make or break contact with the help of a signal without any human involvement in order to switch it ON or OFF. It is mainly used to control a high powered circuit using a low power signal.
What is relay principle?
Relay works on the principle of electromagnetic induction. When the electromagnet is applied with some current, it induces a magnetic field around it.
What is relay Explain with suitable diagram?
Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized.
What are the two types of relay event?
The two most common relay races in track and field are the 4 x 100m and the 4 x 400m races, in which four athletes run 100m and 400m each respectively. A less common relay is the sprint medley relay, usually consisting of four legs run at distances of 400, 200, 200, and 800 meters.
What are relays in sports?
At the Olympics and other World Athletics-sanctioned tournaments, a relay race is an event where a team of four athletes run equal predetermined distances in a sprint race, each passing a rod-like object called the ‘baton’ to the next person to continue the race. The last runner in a relay is called the ‘anchor’.
What is application of relays?
Application Of Relay Relays are used for isolating a low voltage circuit from high voltage circuit. They are used for controlling multiple circuits. They are also used as automatic change over. Microprocessors use relays to control a heavy electrical load.
