Abstract
PURPOSE:To make it possible to give delay to a signal properly according to the mode of a process instrumentation system and output this signal, by converting the analogue input signal to a digital signal to generate arbitrarily a wasteful time digitally. CONSTITUTION:The analogue input signal inputted to input terminal 11 from the external is converted to a digital value by A-D converter 10 and is supplied to succeeding micro processor 12, and here, digital values inputted momentarily are stored at the beginning of table 13' of table size k of RAM 13 as (current read value-preceding read value)=DELTAx. Wasteful time L set arbitrarily by wasteful time generator 14 is inputted to processor 12 and is collated with the time signal of time signal generation part 15 to detect original electric wasteful time L, and micro processor 12 has interrupt period DELTAt to operate k.DELTAt/L; and when DELTAx of table 13' is moved successively by this time to read the sum of DELTAx, digital values are outputted with a delay of time L. Then, the read output is subjected to D-A conversion, so that the input signal may be outputted with a delay of time L.
