REX521GHHPSH51G is a microprocessor-based decentralised integrated control system. The DCS system integrates computer technology, network communication technology, automatic control technology, redundancy and self-diagnostic technology, and adopts a multilayered hierarchical structure, which is suitable for the control and management needs of modern production, and it has become the mainstream system of industrial process control.

REX521GHHPSH51G integrates computer, instrumentation and electric control technology together, and combined with corresponding software, it can realise such functions as automatic data collection, processing, process screen display, parameter over-limit alarm, equipment fault alarm and report printing, etc. It also forms a historical trend record of the main process parameters, which can be viewed at any time and sets up a safe operation level, which is not only convenient for management, but also makes the system It is not only convenient for management, but also makes the system run more safely and reliably.

REX521GHHPSH51G in the control of the most important feature is to rely on a variety of control, operation module of the flexible configuration, can be achieved to diversify the control strategy to meet the needs of different situations, so that in the unit combination of instrumentation to achieve a rather cumbersome and complex proposition has become simple. With the requirements of high flexibility and high efficiency of enterprise reform, the control scheme based on classical control theory can no longer be adapted to the multivariate predictive control as a representative of the advanced control strategy proposed and successfully applied, advanced process control by the process industry’s general attention!
