Relelogiikkaa
Relelogiikkaa, often translated as relay logic, is a method of designing and implementing control systems using electro-mechanical relays. It is a foundational concept in the history of automation and industrial control. In a relay logic system, electrical circuits are constructed using combinations of relays, which act as electrically operated switches. When a relay is energized, its contacts change state, either opening or closing a connection in another part of the circuit. By arranging these relays in specific configurations, complex logical functions such as AND, OR, and NOT can be implemented, allowing for sequential operations, interlocking mechanisms, and safety interlocks in machinery and processes.
The design of relay logic systems typically involves creating ladder diagrams, a type of schematic that visually
