ANALOG UNIT FOR SEQUENCER SYSTEM

摘要

An analog unit having a multiple channel configuration among analog units provided in a sequencer system comprises: setting means to which an alternating current signal to be measured that is taken in by a CT censor for each of the plurality of channels can be directly inputted, for setting, in an internal memory, an abnormality assessment peak current value and an abnormality peak current continuation time to be applied relative to the alternating current signal to be measured for each of the plurality of channels; and detection means for detecting the occurrence of abnormal alternating currents when an alternating current signal in which the abnormality peak electric current continuation time is maintained in a state in which the peak value exceeds the abnormality assessment peak electric current value is included in the alternating current signal to be measured for each of the plurality of channels.
