ABB Flagship DCS

ABB System 800xA — Extended Automation

A powerful and flexible Distributed Control System that goes beyond traditional control by integrating control, safety, electrical, and asset management into one unified platform.

System 800xA

One Platform. Total Plant Control.

ABB System 800xA (Extended Automation) unifies process control, safety systems, electrical switchgear, and asset management under a single engineering and operations environment — eliminating silos and reducing total cost of ownership across the plant lifecycle.

As an ABB Value Provider – System Integrator, Hi-Tech Automation designs, supplies, programs, and commissions System 800xA installations for India's most demanding process industries.
