When the relay is activated, the NO contact closes, allowing current to flow through it. Conversely, the NC contact is initially closed, meaning there is a complete electrical connection between the common terminal and the NC terminal. When the relay is activated, the NC contact opens, breaking the electrical connection.
The wiring diagram provides a clear visual representation of how the contacts are connected and how they interact with other components in the circuit. By understanding the role of the contacts and their connection within the wiring diagram, individuals can effectively design, troubleshoot, and maintain electrical systems that incorporate 5-pin relays.
