ーラの出力チエツク装置。[Scope of Utility Model Registration Claim] In a controller that processes required input information using a microprocessor and outputs an output signal indicating a predetermined output instruction via an output line, the controller outputs an output signal from the output line. It is equipped with an extraction circuit that extracts a signal, and a conversion circuit that converts the level of the output signal extracted by the extraction circuit into a state that can be input to the microprocessor and returns it to the microprocessor. Compare the output instruction and the signal instruction returned,
An output check device for a controller, characterized in that when both instructions are equal, it is determined that the output line is normal, and when both instructions are different, it is determined that the output line is abnormal.
