Abstract:
    A control device with a forced operation function comprising an output circuit operating while interlocking with an internally generated output control signal, and a terminal for leading a signal from the output circuit to outside. A signal detection circuit for outputting a forced operation signal when a predetermined signal is inputted to the terminal from outside is provided. The internally generated output control signal and the forced operation signal obtained by the signal detection circuit are added to the output circuit through an OR circuit. With this structure, the number of terminals of the control device with a forced operation function may be reduced and a lower cost may be realized.
