First Out Annunciator


The First Out Indicator is designed to be a cost effective means of adding diagnostics to a machine to detect faults in the operational and safety circuits of electrical equipment.  The First Out Indicator monitors up to eight points in a series string of contacts, such as proxs, limit switches, photo eyes, contactors, push-buttons, relay contacts, etc.  The First Out Indicator will latch and hold the first failed contact in a string and indicate that fault.  If more than eight points need to be monitored, two or more units can be combined.
