ABB PFSK142 3BSE006505R1全新现货DCS控制系统电源模块

高炉自动控制上所应用的分布式控制系统, 一般按对电气逻辑顺序控制功能与仪表连续调节控制功能的不同侧重分为两类: 一类是电气逻辑顺序控制功能与仪表连续调节控制功能均由同一类型控制器进行控制的全DCS 控制系统

如美国西屋(Westinghouse) 公司的OVATION 控制系统, 德国西门子公司的PCS7 控制系统等; 另一类是电气逻辑顺序控制功能与仪表连续调节控制功能分别由不同类型控制器进行控制的“PLC + DCS”控制系统,

如由美国霍尼韦尔公司的仪表连续调节控制器HPM 与美国GE 公司的电气逻辑顺序控制PLC 共同组成的Total Plant 控制系统,由日本横河公司的仪表连续调节控制器FCS 与日本安川公司的电气逻辑顺序控制器CP23500H 共同组成的控制系统等。

The distributed control system applied in the automatic control of blast furnace is generally divided into two categories according to the different emphasis on the electrical logic sequence control function and the instrument continuous regulation control function: one is the full DCS control system where the electrical logic sequence control function and the instrument continuous regulation control function are controlled by the same type of controller

Such as the OVATION control system of Westinghouse, Germany Siemens PCS7 control system, etc.; The other is the "PLC + DCS" control system with the electrical logic sequence control function and the instrument continuous adjustment control function respectively controlled by different types of controllers.

For example, the Total Plant control system composed of HPM, an instrument continuous regulation controller from Honeywell, and an electrical logic sequence control PLC from GE, is composed of FCS, an instrument continuous regulation controller from Yokogawa, Japan, and CP23500H, an electrical logic sequence controller from Yaskawa, Japan Jointly composed control system, etc.
