Instrument control design principle and scope of supply

DCS concentrating and dispersing control system will be decided by final design for selction of the provisions. 2 operation platforms are in the operating rooms to monitor the parameters of the plant with the function of display, operation, regulation, memory , starting and protection interlock. The interlock function can start and stop the plant automatically according to the requirement, which also can be operated manually. There is 1 printer in the operation room to print the parameters and functions when the plant is running. There are Local panels for each machinery, which can display parts of parameters, oeprating, alarm and interlock. There is a analysis room. The analysis device is in the panel, the parameter is displayed, recorded and alrmed in DCS system. Instrument power: 220VAC and 24VDC. DCS system needs continually power supply. The power for instrument system is supplied by the power supply plate of the instrument system.
