SpletA very common form of schematic diagram showing the interconnection of relays to … Splet01. avg. 2006 · Relays are electrically controlled devices that open or close electrical contacts to affect the operation of other devices in the same or different circuits. A relay's most basic components are its coil, armature, and contacts. When the relay is put into a given circuit, the current from that circuit induces a magnetic field in the relay coil. SpletSuch relays can be divided into two groups: relays with HV insulation for all current-carrying elements switching high voltages, and relays with low-voltage (LV) contacts and high voltage insulation between the input elements (control coil) and the … dfar short of award memorandum
