Remote Telemetry Units (RTUs) are a core component of modern Supervisory Control and Data Acquisition (SCADA) systems. These robust devices are deployed at critical asset sites such as electricity substations, water treatment plants, or railway switching points where they excel in monitoring, collecting, storing, and analyzing data, and even executing automated actions based on that data.

RTUs are versatile and highly configurable, allowing operators to select specific parameters to monitor and set thresholds for triggering automated actions. For example, an RTU can automatically activate a heater if temperatures drop below a predefined level or adjust pumping schedules based on water flow readings. This adaptability makes RTUs indispensable for a wide range of industries and environmental conditions.
