The invention concerns an electric circuit designed to control a power supply of a piece of electrical equipment, the electric circuit comprising a piece of electrical equipment and a source of supply voltage, and further having, as inputs, at least two discrete electrical signals of which the values condition the cutting off of the power supply to the piece of equipment, the circuit being characterized in that it further comprises:—a module for the redundant comparison of the discrete electric signals, comprising two branches for comparing said signals, parallel to one other, each branch being designed to supply, at the output, a control signal representative of each of the comparisons of said discrete electrical signals, and—a first module for cutting off the power supply to the piece of electrical equipment comprising two switches in series, each one being controlled respectively by one of the two control signals. The invention also concerns a system for acquiring, processing and communicating avionics data installed in an aircraft, comprising such an electric circuit.
