Abstract
A load control apparatus includes: a relay control unit that outputs an open or close command; a power supply adjustment unit; a contact resistance measurement unit that measures a resistance value of the relay; and an adjustment command generation unit that outputs to the power supply adjustment unit an increase command that causes a current flowing between the contacts of the relay or a voltage applied therebetween to be a value greater than a steady-state value when the resistance value becomes greater than or equal to a predetermined threshold value, and outputs to the power supply adjustment unit a release command that returns the current flowing between the contacts of the relay or the voltage applied therebetween to the steady-state value when, after the increase command is outputted, the resistance value becomes smaller than the predetermined threshold value and the close command is received from the relay control unit.
