What is Understanding Relays and Contactors about?

Relays and contactors are electrically operated switches that use coils to control contacts. Relays have a coil that energizes to turn the relay on, and a spring that restores it to the off position. Ladder logic diagrams depict how relays, contacts, and other devices are interconnected, representing the electrical logic of a control system. Multiple relays are often used together, with contacts sharing an identifier linked to the same coil.
