Abstract

Examples described herein provide a method for direction control of a motor of a gate crossing mechanism. The method includes providing, by a field-effect transistor (FET) driver, a first voltage via a high output to an open contact of a first relay and to a closed contact of a second relay. The first voltage causes a shaft of the motor to turn in a first direction. The method further includes providing, by the FET driver, a second voltage via a low output to a closed contact of the first relay and to an open contact of the second relay. The second voltage causes the shaft of the motor to turn in a second direction opposite the first direction.
