Description

ABB 07AA61 has been widely used in various fields of human society. In industry, there are corresponding control systems for various physical quantities encountered in the production process of metallurgy, chemical industry, machinery manufacturing, including temperature, flow rate, pressure, thickness, tension, speed, position, frequency, phase, etc. On this basis, a digital control system with better control performance and higher degree of automation, and a process control system with dual functions of control and management have been established by using digital computer. Applications in agriculture include automatic water level control system, automatic operating system of agricultural machinery, etc.

07AA61

The ABB 07AA61 control system has been in use since the 1940s, with early field based meters and later relays forming the predecessor of the control system. Represented by PLC and DCS, since the application of **** in 70 years, it has achieved rapid development in industrial process control such as metallurgy, electric power, petroleum, chemical industry and light industry. Since **** in 1990, fieldbus control systems and PC-based control systems have appeared one after another. This paper will briefly introduce various common control systems, and analyze the evolution process and development direction of control systems.
ABB 07AA6170 in the middle of the decade, due to the large size of equipment, high requirements for process continuity, increased process parameters to be controlled, and harsh conditions, requiring centralized display operation, etc., so that the already popular electric unit combination instrument can not fully meet the requirements. In this case, the industry manufacturers through market research, determined that the development of DCS products should be based on analog quantity feedback control, supplemented by switching quantity sequence control and analog quantity switching quantity mixed batch control, they can cover oil refining, petrochemical, chemical, metallurgy, electric power, light industry and municipal engineering and other most industries.
