Claims

[Scope of utility model registration request]

In a multi-system control device that has a plurality of power supplies corresponding to a plurality of control devices and switches that individually open and close the power supplies, an abnormality signal of the control device indicating an abnormal state of each of the control devices and an abnormality signal of the control device that indicates an abnormal state of each of the control devices and a plurality of AND circuits to which a power supply failure signal of a control device and a power supply switching signal of each of the control devices are input; a plurality of OR circuits to which outputs of the plurality of AND circuits are supplied; and outputs of the OR circuits are supplied. A multi-system control device comprising: a determination OR circuit for sending an output signal for determining whether or not the control device is operable;
