The redundancy control device (350, 450) includes three controllers (11, 12, 13) that output status signals (N1, N2, N3), a majority voting circuit (70) to which a first voltage or a second voltage is supplied as an output signal (T) through an output line (91, 92, 93) of each controller, a switch (41, 42, 43) provided in each output line, a voltage supply unit (51, 52, 53) provided for each output line to supply the second voltage to the output line when the first voltage is lost, a latch circuit (61, 62, 63) provided for each output line to latch the second voltage when the second voltage is supplied thereto and continue to output the second voltage, a comparison circuit (31, 32, 33) provided for each controller to output a comparison signal (C) based on a comparison of the status signals, and a switch control unit (81, 82, 83) provided for each switch to outputs a switch signal (K) to the switch in response to the comparison signal from the comparison circuit.
