Model KJD13 Mine-used I.S. Programmable Controller is used as automatic monitoring and control device for coal mine underground with a danger of explosion of methane and coal dust. It also can be used as monitoring and control device in severe situations like metallurgical, mine, open pit, port, coal preparation plant and power plant.
The controller utilizes modular design with flexible configuration, Chinese display, programming mode of statement list and trapezium graph; program writing and modifying can be done by special I.S. programmer, very convenient for testing, using and maintenance.
