Difference between RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit)




RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit) are the two components that are interconnected but they have different meanings and functions. To know more details, here are an explanation of the difference between RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit).

RTAC and RTU


The Definition of RTAC and RTU

The first difference between RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit) is on understanding. RTC is a real-time operating system, communications, data concentration, logic processing in the form of a chip and storing data that has been recorded in real time. Because it works in real time, the counting time after time then the data is immediately stored and sent to the device through the system advance. RTAC commonly found in PC motherboard or any type of computer.

While RTU or remote terminal unit is one of the components of the SCADA equipment created to monitor the activity of a substation for an electric power system. Information on the electric power system obtained from monitoring and measuring electrical quantities on the parent unit. After it, the information will be processed by the RTU and will be sent to the control center, the process is called tale information consisting of tale signal, tale control and tale metering. RTU can also be connected with one or two master station or linked to other RTU via communication lines.


The Function of RTAC and RTU

The second difference between RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit) is seen from the second function. RTAC basically serves to the data concentration, client/server communications, logic processing accurately and precisely. While the function RTU is to process input and output by connecting the main substation RTU via analog input or output modules and digital. RTU can also be used to collect data from smart meters and LED as a safety relay. Additionally RTU can be used for event logger by connecting one or two printers and alphanumeric terminals. The last RTU can do the configuration with needs that do use the database system.

Those are difference between RTAC (Real-Time Automation Controller) and RTU (Remote Terminal Unit) views of the meaning and function. To be able to use both the component properly you need to understand fully the differences between the two. You can use these two components in accordance with their respective functions.
