PURPOSE:To perform stable operation, even if a selective signal is abnormal as to one system of a doubled controller, by the other controller by using a trains of pulses as the selective signal. CONSTITUTION:When the selective signal of controller CONT0 is at a high potential, AND circuit 1 outputs a train of connected pulses. Then, the output of retriggerable monostable multivibrator 8, when resistance 10 and capacitor 12 are adjusted to timing longer than the pulse period of its input, is constant as far as pulses are inputted continuously. |
