= Relay logic
{wiki=Relay_logic}
Relay logic is a control system design methodology that uses electromechanical devices called relays to control electrical circuits. This technique is commonly used in industrial automation and control systems. Key features of relay logic include: 1. **Electromechanical Relays**: Relay logic systems rely on relays, which are electrically operated switches. By energizing a relay coil, the contacts can open or close, allowing or interrupting the flow of electrical current in a circuit.
