Abstract

A relay control device includes a coil, a movable iron armature that is switched from an open state to a closed state when the coil is excited, a switching current output circuit that applies first current for switching the movable iron armature from the open state to the closed state to the coil, and a holding current output circuit that applies second current for holding the movable iron armature in the closed state to the coil. The switching current output circuit applies the first current to the coil when a first time has elapsed from when the second current is started to be applied to the coil, and the value of the second current is lower than the value of the first current.
