INTERFACE MODULE BETWEEN A LAND BUS AND AN ELECTRICAL GOVERNMENT EQUIPMENT AND PROTECTION OF AN ELECTRIC MOTOR.

摘要

THE PRESENT INVENTION REFERS TO AN INTERFACE MODULE BETWEEN A FIELD BUS (B) AND AN ELECTRICAL EQUIPMENT (C) FOR THE CONTROL AND PROTECTION OF AN ELECTRIC MOTOR (M), WITH THIS MODULE INTEGRATED CIRCUIT (2) PROVIDED WITH TERMINALS OF DATA (D0, D1, D2, D3) CONNECTED BY INPUT / OUTPUT CIRCUITS TO CONTACTS OR TOR DETECTORS (A {SUB, 1}, A {SUB, 2} .A {SUB, 3}, A {SUB, 4} , A {SUB, 5}, A {SUB, 6}) OR COILS OR ACTUATORS (KM1, KM2, KM3) OF THE ELECTRICAL EQUIPMENT (C), CHARACTERIZED BY THE HEHCO THAT THE DATA TERMINALS (D0, D1, D2, D3) OF THE INTEGRATED CIRCUIT (21) ARE CONNECTED, BY LOGIC CIRCUITS, TO INPUTS OR OUTPUTS (A, T, LI1, LI2, LO1, LO2, S) WHOSE NUMBER IS GREATER THAN THE NUMBER OF DATA TERMINALS (D0, D1, D2, D3), WITH THESE INPUTS / OUTPUTS CONNECTED TO THE COILS OR ACTUATORS (KM1, KM2, KM3) AND TO THE AUXILIARY CONTACTS OR TOR DETECTORS (A {SUB, 1}, A {SUB, 2} .A {SUB, 3 }, A {SUB, 4}, A {SUB, 5}, A {SUB, 6}) OF THE ELECTRIC DEVICE (C).
