WebApplication of Relay. The application of control systems and automation circuits need the logic state and logic gates. The logic gates are represented by open and closed state of switches or relays. Later we will use the terms of NO (Normally Open) and NC (Normally closed) when talking about relays and switches when the coil is generated. WebThe KYZ relay generates pulses. The term KYZ refers to the contact designations: K for common, Y for Normally Open, and Z for Normally Closed. When incorporated into an electrical meter, the relay changes state with each full or half rotation of the meter disc. Each state change is called a "pulse."
