Function
Relays are electromechanical devices that are used to control the flow of current in a circuit. They are used in a wide variety of applications, including power distribution, industrial automation, and telecommunications. The symbol for a relay in a wiring diagram is a rectangle with two coils and two contacts.
- Controlling Current Flow: Relays are used to control the flow of current in a circuit by opening and closing contacts. When a relay is energized, the contacts close and allow current to flow through the circuit. When the relay is de-energized, the contacts open and stop the flow of current.
- Isolation: Relays provide isolation between two circuits. This means that the two circuits are not electrically connected to each other, even when the relay is energized. This is important for safety and to prevent damage to the circuits.
- Amplification: Relays can be used to amplify a small control signal to control a larger load. This is done by using the relay to switch a larger current on and off.
- Logic: Relays can be used to implement logic functions. This is done by using the relay contacts to create different combinations of open and closed circuits.
By understanding the function of relays and how they are used in wiring diagrams, you can more easily design, troubleshoot, and repair electrical circuits.
