ABSTRACT:
An improved monitoring system which identifies the particular event (contact operation) and therefore the particular electromechanical relay (20, 22, and 24 which operated). This information is output from a MCU (30), along with the relative time the event occurred, to a PC and an LCD display (40). In addition, the relative occurrence time is recorded to the thousandths of a second.
