What is the diagram of relay?
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 is relay pin diagram?
Relays control circuits by opening and closing contacts in another circuit. It take a relatively small amount of power to operate the coil, but this itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power.
How does a 5 point relay work?
5 Pin Relay 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. They have both normally open and normally closed connection pins. When the coil is activated, power will be switched from the normally closed pin to the normally open pin.
How a relay works 12v?
Relays install between the power source and the electrical accessory requiring on/off power. When the relay is energized, the high current to operate the accessory flows from the power source, through the relay, and directly to the part.
What is the symbol of relay?
A single pole switch is often denoted by the letters SP, and a double pole by DP. Relays can have one, two or more poles. Throw: The number of throws on an electrical switch is the number of positions that are available. For an electromechanical relay, there are normally only one or two throws.
What is the principle of relay?
Relay works on the principle of electromagnetic induction. When the electromagnet is applied with some current it induces a magnetic field around it.
What are the two types of relay?
Types of Relays – A Thomas Buying Guide
- Relays are electrically operated switches.
- Electromechanical relays have an electromagnetic coil and a mechanical movable contact.
- Solid-state relays are solid-state electronic components that do not have any moving components, which increases their long-term reliability.
What are the terminals on a relay?
Understanding Relays, part 2: DIN numbers and different types of relay
| Terminal | Which Circuit? | Definition |
|---|---|---|
| 86 | Low current (control) | Relay coil + (power input) |
| 85 | Low current (control) | Relay coil – (ground) |
| 30 | High current (load) | From battery + |
| 87 | High current (load) | Output to device, normally open, pulled closed when coil is energized |
