Relay logic

Relay logic is a system of controlling electrical devices using relays—electromagnetic switches that open or close circuits in response to signals. Think of relays as automated switches: when a specific input signal or condition occurs, the relay activates, allowing current to flow and power devices or machinery. This method enables complex control systems where multiple conditions and actions are coordinated without human intervention, often used in industrial automation. Essentially, relay logic uses simple electrical components to create reliable, programmable control sequences for machinery and processes.
