Abstract
PURPOSE: To quickly discriminate the trouble location and trouble conditions of a transistor which drives a relay, a solenoid or the like by detecting and diagonosing by an on-line operation the unsatisfactory function of the transistor due to damage or trouble.
CONSTITUTION: In response to a drive instraction produced as output from a control circuit 1 a transistor 4 connected to a load 6 such as a relay or the like is turned on only during a period where a drive instruction exists, and is put in a driving state to drive the load 6. By a detection signal from drive detection means provided in the transistor 4 and a timing signal produced from the drive instruction, any damage or trouble of the transistor 4 is digitally detected. the detection signal thus obtained is immediately subjected to an on-line operation.
