标题 Relay Wiring: Understanding the Basics and Applications
Relay wiring is a fundamental aspect of electrical and electronic systems, often serving as the backbone for controlling higher-power circuits with low-power signals. A relay is an electromechanical switch that allows one electrical circuit to control another. This means you can control a high voltage circuit with a low voltage signal, which is critical in various applications ranging from automotive systems to industrial machinery and home automation.
What is a Relay?
At its core, a relay consists of an electromagnetic coil, an armature, and a set of contacts. The coil generates a magnetic field when electricity passes through it, causing the armature to move. Depending on the relay design, this motion can either close or open a set of contacts that control the circuit being switched. Relays can be categorized based on their configurations—commonly known as normally open (NO) and normally closed (NC) contacts.
