Abstract
The objective of the present invention is to provide a relay-welding detection device and method, the device and method capable of determining, whether a relay is welded, by using an analog-digital converter (ADC). Another relay-welding detection device according to the present invention comprises: a first ADC for measuring a voltage of a relay input terminal; a second ADC for measuring a voltage of a relay output terminal; and a CPU for comparing the voltage of the relay input terminal with the voltage of the relay output terminal and determining whether the relay is welded.
