What You'll Learn
RTU stands for Remote Terminal Unit
RTUs are used in industrial automation systems to increase the functionality of a device. They are often used to extend the existing features of a device, such as increasing a computer's memory capacity or adding more ports. They are an integral part of industrial automation and are used in many sectors, including chemical plants, sewage and water treatment plants, food processing, automobile and pharmaceutical manufacturing, and petrochemical (oil) refineries.
RTUs are designed to operate under a wide range of harsh conditions, such as extreme temperatures, high vibrations, and chemical exposure. They are more rugged than PLCs (programmable logic controllers), which are designed for milder physical environments. RTUs are also capable of executing simple programs autonomously, without involving the host computers of the DCS or SCADA system, providing redundancy and simplifying deployment.
RTUs may consist of a single complex circuit card with various sections or multiple circuit cards, including a CPU or processing with communications interfaces, and one or more of the following: analog input, digital input, etc. They may be interfaced with multiple master stations and IEDs (intelligent electronic devices) using different communication protocols, and they can support standard protocols to interface with third-party software. RTUs can also include a backup power source, such as a battery or solar panel, ensuring continuous operation even during power outages.
