Abstract
The utility model relates to a novel pilot lamp control circuit, wherein: the first output OUT1 of first subsystem showes that first subsystem is in normal condition during for the low level, and the second output OUT2 of second subsystem showes that the second subsystem is at normal condition during for the low level. When at least one was the high level in first output OUT1 or second output OUT2, the emitting diode LED lamp extinguish, and at least one broke down during this moment identification received first subsystem or the second subsystem of control. So, it shows only to need an opto -coupler can solve two separant system votes. Not only economy can effectively reduce the integrated circuit board space moreover.
