🎥 If you are searching for a solution to keep track of remote measuring stations, the Remote Terminal Unit or RTU is your best choice. The RTU is sometimes referred to by other terms such as Remote Telemetry Unit or Remote Telecontrol Unit.

By watching this video, you’ll get the answer to these questions:
- What is RTU?
- How does RTU work?
- When is RTU needed?
- What is RTU is SCADA?
- What does RTU stand for?
- What are RTU components?
- What is the difference between RTU and PLC?

💬 Video Summary:

Where RTU is used
- Where most of the time, nobody is out there, there is no connection to the electricity grid, and no wired connection can be established

RTU Meaning
- An RTU is a rugged standalone microprocessor-based electronic control device deployed in an industrial environment at specific locations, which informs plant operators about what's going on out there all the time.

RTU Function
- The RTU acts as a local connection point to gather measured data from connected sensors. The RTU performs data processing on the aggregated data, and as a result, the received raw data is scaled and translated into a transmittable format. One way to achieve converted data from RTU is through the web interface via a PC.

RTU Communication with SCADA
- When the number of RTUs increases, it is preferable to have a central master station. Here, RTUs establish interfaces between field instruments in physical processes and the automation control system.

RTU Hardware
- The main components of an RTU include the power source, central processing unit (or CPU), discrete inputs, analog inputs, control relay outputs, and communication interface, which can be a port or an external antenna.

Differences between RTU and PLC
- Although RTUs and PLCs share many common characteristics, there are some dividing lines.
