Electromagnetic and electronic relays. Part I: relays and contactors

Abstract

The relays are devices designed to produce certain modifications, when certain conditions in an electrical circuit that influence him in the same circuit or in another. The circuit acts on the relay acts as a control or signaling. Is the world of industrial automation systems. In this article we will restrict ourselves to the electromechanical relays and electronic circuits, by extension, have been called electronic switches or relays. An electromagnetic relay as one remote control switch, which returns to the idle position when the actuating force ceases to act on it.
