Types
In the context of a 90 340 relay wiring diagram, the distinction between normally open (NO) and normally closed (NC) contacts is crucial for understanding the relay’s behavior and its impact on the controlled circuit.
-
Normally Open (NO) Contacts
In a NO configuration, the contacts are open in the relay’s default state, meaning the circuit is incomplete and no current flows through the load. When the relay is energized, the contacts close, completing the circuit and allowing current to flow to the load.
-
Normally Closed (NC) Contacts
In an NC configuration, the contacts are closed in the relay’s default state, meaning the circuit is complete and current flows through the load. When the relay is energized, the contacts open, breaking the circuit and interrupting the flow of current to the load.
The choice between NO and NC contacts depends on the specific application and the desired behavior of the controlled circuit. Understanding the difference between these two types of contacts is essential for correctly interpreting and utilizing a 90 340 relay wiring diagram.
