Abstract

PURPOSE: To improve the reliability of the entire part of the unit by providing two high (low) value priority devices and two deviation alarms for two detectors with respect to the same process state quantity thereby achieving perflect duplication of signals.
CONSTITUTION: Process state quantity 1 is passed through detectors 2a, 2b and signal converters 3a, 3b, from which it is duplicated and drawn out and is then applied to both of high (low) value priority devices 4a, 4b, from which the selected priority signals Sa, Sb are separately outputted. Here, if there is any abnormality in the output of either of the signal converters 3a, 3b, an alarm is immediately produced from a deviation alarm 5, and if there is an abnormality in either of the priority devices 4a, 4b, an alarm is immediately produced by a deviation alarm 6, thus remedy may be promptly taken.
