Universal programmable process control apparatus

摘要: Apparatus for selectively enabling and disabling a process depending on the instantaneous value of measurement made during in accordance with predetermined program recorded by shading adjacent segments an area record means length which is analog total range each representing interval to be enabled or disabled. A plurality memory cores one correspondence subsegments are caused programming occupy two bistable states response light sensor responsive originating from incident source reflected record. After programming, interrogated control switch set state corresponding last core.
