<p>PROBLEM TO BE SOLVED: To simplify the final stages with standard circuit components and guarantee a protective function by allowing the circuit units inputting the physical quantities for the final stages to respond to the nonproblematic changes of physical quantities via the safety function of the succeeding final stages and/or accessory electricity consuming components. SOLUTION: Circuit units 41 -4n connected to a micro-computer 1 via communication channels 6, driving electricity consuming components 71 -7n connected via the final stages 51 -5n of power semiconductors respectively, and provided for protection are connected to computing systems 21 -2n . When physical quantities such as voltage, current, and temperature and detected by the interface devices 31 -3n connected to the final stages 51 -5n and introduced to the computing systems 21 -2n , some safety function is activated for the time-wise nonproblematic changes of these physical quantities by the communication channels 6 connected to the micro-computer 1 together with the final stages 51 -5n and/or the electricity consuming components 71 -7n .</p> |
