Understanding Remote Terminal Unit (RTU)

A remote terminal unit RTU is a microprocessor-based field device used in SCADA and industrial control systems to monitor sensors and control equipment at remote sites. It collects telemetry from instruments, executes control commands, and transmits data back to a central master station or control center, often over wide-area communications links. RTUs are a frequent target in OT security because they bridge physical processes and networked control systems.
