General Electric created the 531X146BDHALG3 for industrial applications. The 531X146BDHALG3 is a PCB (printed circuit board) base driver circuit board. This circuit board has connection points where wires can be attached, along with a point in the center to attach a wiring harness as well as smaller white connection points along the outside edge and towards the center of the circuit board. All the wires attach into a large black box in the center of the circuit board.
