Power supply to power the programmable controller In the power system, using 220V DC power supply (battery) to power the programmable controller can significantly reduce the interference from the AC power supply, and can also ensure the normal operation of the programmable controller when the AC power supply disappears. In the power input terminal of some programmable cont...
A power plant, 2×300MW coal-fired units The thermal system is a unit system . Each unit is equipped with a centralized control building, which adopts the centralized control mode of machine , furnace and electric unit . The elevation of the unit control room is 12.6m, which is consistent with the elevation of the operation floor . DCS adopts WDPF-Ⅱ, and the I/O points designed for eac...
(1) The DCS system is a large system. Its controller has powerful functions and plays an important role in the system. The data highway is the key to the system. Therefore, the overall investment must be made in one step, and sub- sequent expansion is difficult. However, the functions of FCS are completely decentralized, information processing is on-site, and digital intelligent field de...
In the past few decades, industrial automation has gradually developed and the market structure has not changed much. However, due to technological disruptions and the impact of major trends such as repositioning, global skilled labor shortages, and efforts in environmental,social, and governance (ESG), the pace of change is accelerating. Many of the most advanced manufacturing technologies today,...
