Title:
RELAY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/207231
Kind Code:
A1
Abstract:
This relay control device (100) is provided with: a coil (3); a movable iron piece (4) that is switched from an open state to a closed state when the coil (3) is excited; a switching current output circuit that allows a first current to flow to the coil (3), the first current switching the movable iron piece (4) from the open state to the closed state; and a holding current output circuit that allows a second current to flow to the coil (3), the second current holding the closed state of the movable iron piece (4). The present invention is characterized in that the switching current output circuit allows the first current to flow to the coil (3) when a first time has elapsed from the time point at which the second current starts to flow to the coil (3), wherein the value of the second current is lower than the value of the first current.
