Abstract: A device and method are provided for the redundant control of a power controlled device (R). The redundant control device comprises two programmable controllers (A.sub.1, A.sub.2) adapted for elaborating a control order. These two programmable controllers (A.sub.1, A.sub.2) are equipped with two respective logic circuits designed so as to apply to two outputs (s.sub.1, s.sub.2) two logic signals (S.sub.1, S.sub.2) whose combination using the EXCLUSIVE OR function is the image of the control order. The power device (R) is then controlled by a control member (O) connected by its two inputs, to said two outputs (s.sub.1, s.sub.2) and performing the logic EXCLUSIVE OR function of the signals (S.sub.1, S.sub.2) delivered by these two outputs. With this device, independently of the breakdown state of one of the two control circuits, the state of the controlled device always corresponds to the control order.
