Abstract: A secure conversion device for an aircraft equipped with a digital computer and an analog actuator, said device being capable of converting discrete digital controls provided by the computer into analog power signals transmitted to the analog actuator and making it possible to steer said actuator, comprises a security module, making it possible to identify inconsistencies in the discrete digital controls and to interrupt the transmission of the analog power signals toward the analog actuator when an inconsistency in the discrete digital controls is identified. The device also comprises a detection module, making it possible to determine power levels of the analog power signals. The device also comprises a monitoring module, making it possible to detect anomalies in power supply levels of components of the device.
