China Automated Industry Distributed Control System Programmable Logic Controller

DCS/PLC Control System
DCS is the abbreviation of Distributed Control System. It is anew generation of instrument control system based on microprocessor, adopting control function dispersion, display operation concentration, and taking into account the design principle of separated autonomy and comprehensive coordination. It can also be translated as "Distributed Control System" or "Distributed Computer Control System".It adopts the basic design idea of controlling decentralization, operation and management concentration, as well as amulti-layer hierarchical, cooperative andSafety Products & Supplies autonomous structure. Its main feature is its centralized management and decentralized control. At present, DCS has been widely used in various industries such as power, metallurgy and petrochemical industries.DCS usually adopts hierarchical structure, each level consists of several subsystems, each of which implements certain specific limited targets to form apyramid structure.Reliability is the life of development for DCS. There are three main measures to ensure the high reliability of DCS: The first is the extensive application of high-reliable hardware equipment and production technology; The second is the extensive use of redundancLinear Actuator y technology; The third is the wide implementation of system fault tolerance technology, fault self-diagnosis and automatic processing technology in software design. Most of today's distributed control systems could have aMTBF (Mean Time Between Failure) of tens of thousands or even hundreds of thousands of hours.Working conditionsEnvironment temperature: Maximum temperature +40 ºC, minimum temperature -10 ºCEnvironment humidity: Daily average≤95%, monthly average≤90%Altitude: No more than 1000 metersAmbient air: Not suOther Manufacturing & Processing Machinery itable for corrosive, combustible gas and other obvious pollution, and no violent vibration placesIn the event of an earthquake, the magnitude of the earthquake should not exceed 8Main technical parametersRated voltage: 40.5kVRated insulation level: Lightning shock resistance (full wave) 185kV; Power frequency withstand voltage (1min) 95kVRated frequency: 50HzRated current: 630A, 1250A, 1600A, 2000ARated short-circuit breaking time: Power frequency withstand voltage: 20s, 25s, 31.5sRated short-circuit closing current (peak): 50KA, 63KA, 80KARated dynamic stability current (peak): 50KA, 63KA, 80KA4s thermal stability current (RMS) 20KA, 25KA, 31.5KAShell protection class: Vacuum circuit breaker cabinet IP4X.Company Presentationabout usShanghai Zhecheng EHeater &Relay & Contactor Heat Exchanger lectric Co., Ltd is founded in 2004, mainly engaged in industrial automation of complete sets of equipment and related solutions.
