Description

Honeywell 51304446-250 UCN Digital
Honeywell 51304446-250 UCN Digital
The analysis of the characteristics of the three electric automation control system for the main process of the new No. 2 blast furnace in the configuration of the 3 PKS system has been known. The main process flow included in the three electric integration automatic control system for control and monitoring includes: the blast furnace ore coke tank and feeding system; Bell less furnace top system; Hot air stove and waste heat recovery system; The main body of the blast furnace and the casting yard system; Gas cleaning system; Among them, there are 533 current 4-20MA analog input points, 815 thermocouple T/C analog input points, 140 thermal resistance RTD analog input points, 146 current 4-20MA analog output points, 1905 digital (DI) input points, and 634 digital (DO) output points. The total number of I/O points is 4173. In order to consider system upgrades and damage to I/O points, there is a 20% margin during system configuration, and the actual total number of I/O points configured is 5136.
