摘要
A relay failure detecting device includes: an opening-closing unit that is driven by a coil for opening and closing a current pathway; a detecting unit that detects a current value of a current flowing in the coil; an opening-closing instructing unit that outputs an instruction signal to instruct opening and closing of the opening-closing unit; and a failure detecting unit that detects a failure in the opening-closing unit by using the current value output by the detecting unit within a predetermined period of time starting from when the instruction signal is output.
