Zusammenfassung:	The utility model relates to an explosion-proof electric controller which is provided with an outer shell with a flame-proof cavity, wherein a control circuit board, a safety grid plate and a display screen, which are connected and assembled in turn, are arranged in the flame-proof cavity, and a cable leading-in component is arranged on one side of the outer shell. The controller is characterized in that an intrinsic safety type related device and a control device are arranged in the shell body, thereby greatly reducing the length of a connecting cable and the manufacturing cost, simultaneously extending the use range of the controller, enabling the controller to carry out the operations of controlling the switch and adjusting the parameter and the like in explosion hazardous areas, and having safe and reliable use.
