IC660TBA026M Power Modules
IC660TBA026M A furnace in which scrap steel or reduced iron is loaded into the furnace so that a three-phase AC arc is generated between it and three artificial graphite electrodes to melt the charge and smelt the steel. The electrode lift of this system is the use of the arc flow of the set value and the actual value of the comparison of differential adjustment, when the set value is greater than the actual value, the electrode down, and vice versa rise, and finally reach the equilibrium point of the process of steady arc smelting. My company 16 # electric arc furnace is the use of this principle of PLC automatic sampling, automatic control of electrode lifting, so as to achieve the automation of the smelting process.
The IC660TBA026M power supply module is always mounted in the first slot of the frame, and the CPU module is mounted in the second slot. the S7-300 connects all modules except the power supply module with the backplane bus. The backplane bus is integrated into the modules, which are connected via U-shaped bus connectors. Each module has a bus connector that plugs into the back of each module.
When installing the IC660TBA026M, first plug the bus connector into the CPU module. And fixed on the rail, and then sequentially loaded into each module. Through the configuration of CPU and DI, DO, AI, AO modules, to ensure that the input and output control of the switching quantity and the collection of arc current and arc pressure, and through the die out to control the electrode lift.
