1. A method for detecting a hardware configuration of a device (2) intended to be carried aboard an aircraft turbomachine and controlled by a two-channel protection calculator (8), comprising:
a power supply able to supply the device that comprises a control module adapted to send a control voltage to the input of the device (2);
a first measuring box (16) able to measure a first voltage (Vs1) at the output of the device; and
a second measuring box (18) capable of measuring a second voltage (Vs2) at the output of the device, the method comprising:
a) sending a control voltage (Vc) to the input of the device (2);
b) measuring the first voltage (Vs1) and the second voltage (Vs2);
c) inferring the hardware configuration of the device (2) from the values of the first and second voltages measured (Vs1, Vs2), by means of the two-channel protection calculator (8), which is adapted to recognize the configuration of the device (2) from said first and second measured voltage values.
