Mining Explosion-Proof Intrinsically Safe Power Supply Box

This combined monitoring system is mainly used for automatic operation, manual control and communication protection of electromechanical equipment in coal mining face with methane explosion gas and coal dust explosion hazard. especially for the control, communication, conversation, the protection system of the belt conveyor and other small installation


Product Details

THK-I (II) new platform for embedded ARM system, is equipped with 12 inch color LCD screen animation, graphics, Chinese characters display. There are 22 ways output and 48 input in the console, 120 ways output along the two lines, 120 ways input, 24 ways input of analog signal, and it has extended function. The system has the functions of system self checking, forced locking, fault language alarm and position display, and the entire system adopts fast plug-in cable. 

KDW127/24(18)II Mining explosion proof and intrinsically safe power supply box provides intrinsically safe power supply for the whole system.

The power supply input of the system: AC127V(+10%~-25%), 150W Output: 1*DC24V(0.5A), 1*DC18V(1A), 1*DC12V(1A), 2*DC5V(1.2A)
