Flameproof and intrinsically safe power supply control circuit device

The utility model relates to a flameproof and intrinsically safe power supply control circuit device, which is characterized in that the flameproof and intrinsically safe power supply control circuit device mainly consists of a power supply input wiring socket (1), an intrinsically safe power supply output terminal (2), a transformer (3), an intrinsically safe power supply module (5), a relay module (6) and an electromagnetic valve (7). The intrinsically safe power supply control circuit device can be widely applied to environment with explosive gas (methane) and coal dust, in addition, a structure of integrating power supplies in various types into a whole body is adopted, the application range is wide, the use space is reduced, the corresponding sensor equipment can be conveniently controlled through the independent relay output, in addition, the relay can be connected into a peripheral relay, and the utility model adds the expansion function, saves the cost, has compact structure and small size, is very co
