ELECTRICAL SYSTEM FOR CONTROLLING AT LEAST ONE GATE OR DOOR OR SIMILAR ELEMENT OF THE TYPE MOVED ELECTRICALLY

摘要

The electrical system for controlling at least one gate or door similar element of the type moved by means of at least one corresponding electric motor comprises an electric network (NTWRK) consisting of two electric wires adapted to allow the distribution of direct-current power supply and digital information, a central control unit (UC) having two terminals (T1, T2) adapted to be connected respectively but indifferently to the two wires of the network (NTWRK) in order to transmit direct-current power supply and to transmit and receive digital information, a certain number of peripheral units (UP), each having two terminals (T1, T2) adapted to be connected respectively but indifferently to the two wires of the network (NTWRK) in order to receive direct-current power supply and to receive and/or transmit digital information.
