DCS (Distributed Control Systems) is a major category in industrial automation, encompassing hardware and software solutions designed to control and monitor complex processes across various industries. Key products in this category include programmable logic controllers (PLCs), human-machine interfaces (HMIs), industrial PCs, control panels, and communication modules. These systems enable real-time data acquisition, process automation, and centralized management of distributed equipment. DCS solutions are characterized by high reliability, scalability, and robust performance in harsh industrial environments. Typical applications include power plants, oil refineries, chemical processing, and manufacturing facilities where precise control and coordination of multiple subsystems are critical.
