<P>PROBLEM TO BE SOLVED: To provide an illumination control system improved in the efficiency of system establishment and construction. <P>SOLUTION: A photocoupler 11 is arranged in an input terminal device 4, and a voltage-applied contact signal output from an automatic flasher unit is converted to a no-voltage contact signal by the photocoupler 11. Therefore, since the need of arranging an auxiliary relay between the automatic flasher unit 2 and the input terminal device 4 is obviated, the efficiency of system establishment and construction can be improved. <P>COPYRIGHT: (C)2008,JPO&INPIT |
