relejärjestelmiä
Relejärjestelmiä, commonly translated as relay systems or relay networks, refers to a type of electrical control system that uses electromagnetic relays to perform switching functions. These systems are fundamental in automating processes and controlling various electrical equipment. At their core, relays are electromechanical switches. When an electrical current flows through a coil within the relay, it generates a magnetic field that attracts an armature. This movement closes or opens electrical contacts, thereby controlling another circuit.
Relay systems are characterized by their modularity and the ability to create complex logic by combining multiple
Historically, relay systems were a primary method for automation before the advent of solid-state electronics and
