Abstract
Provided are a control system of an electromagnetic relay and an electromagnetic relay. The control system of an electromagnetic relay includes an electromagnet coil, a first resistor, and a first voltage control element. A first terminal of the electromagnet coil is connected to a first terminal of a first power circuit through the first resistor. A second terminal of the electromagnet coil is connected to a second terminal of the first power circuit. The first voltage control element is connected in parallel to the electromagnet coil. The first voltage control element can control the magnitude of the voltage across the electromagnet coil, so that the force to which armature iron is subjected gradually changes.
