Tech & Buying Guide
Main Components of a SCADA System in Industrial Automation
Discover the key components of a SCADA system and how sensors, RTUs, master units, and communication networks integrate to monitor and control industrial processes in real time.
Key Functions of a SCADA System in Industrial Automation
Explore the four core functions of SCADA—data acquisition, communication, visualization, and control—and understand how this system powers industrial automation, process optimization, and remote supervision.
Instrumentation Earthing in Industrial Automation Systems
In industrial automation, earthing provides a safe, low-resistance path for electrical fault currents. It protects both equipment and personnel by diverting excessive current directly into the ground. Proper earthing is fundamental to PLC, DCS, and control system reliability, ensuring stable operation even under fault conditions.
