Abstract

PURPOSE:To secure the electrically easy setting and alteration for the control information by writing at least one unit of the semi-fixed control information necessary for the control operation into the ROM which is capable of erasion and writing electrically. CONSTITUTION:Input voltage signals ei1-ein are drawn in selectively by the command of microcomputer 10 and then converted into the digital quantity via A/D converter 49 to be drawn into RAM14. On the other hand, the control parameter which is written into nonvolatile memory EAROM40 which is capable of erasion and writing electrically via the control parameter setting part or electric transmission part 48 is read out by computer 10 and then undergoes the control operation through computer 10 along with the input signal drawn into RAM14 in the form of the operational input. The result of this operation is delivered to digital signal-pulse duration converter 50 and then turned into the analog quantity through pulse duration analog signal converter 52 to turn into output voltage signals e01-eON.
