Abstract

PURPOSE: To enhance reliability of the control by comparing a signal of the pin board unit with an output signal of the computer and outputting a control signal only when both signals coincide in the automatic control unit which performs a schedule control of apparatus.
CONSTITUTION: When a pin is put in a fixed position of the apparatus selection switch 12 in the pin board control unit 1, an apparatus corresponding to the pined position operates, its schedule time is determined by the control timer 11. Output of the switch 12 is fed to the apparatus operation relay 14 through the selection circuit 13 to perform the on-off control of apparatus. On the other hand, an output signal to the controlled apparatus 2 at each schedule time which is stored in the memory of CPU 31 of the computer system 3 is fed to the relay circuit 33 through the input- output unit 32 to operate the corresponding output relay 34, and the output contact 41 of the corresponding selection circuit 13 is closed.
