<p>PROBLEM TO BE SOLVED: To provide a general-purpose system capable of protecting disturbance. SOLUTION: This system consisting of devices 1 to 5 and power control units 10 and 20 is equipped with a disturbance protection circuit 100 which uses power source determination signals from the power control units 10 and 20 when using respective logical signals outputted from the devices 1 to 5 to provide protection against disturbance until voltages supplied to the devices are determined and switches 111 to 115 and 211 to 215 which previously switch settings through hardware or software according to combinations of the devices 1 to 5 and the power control units 10 and 20 to be supplied with electric power to switch disturbance protection logic based upon the power source determination signals. Consequently, the same disturbance protection circuit 100 is used even for a different system to eliminate the need to use different disturbance protection circuits 100, system by system.</p> |
