RTU (Remote Teminal Unit)
Application:
* Control of electricity transmission and distribution networks
* Control of rail transport networks such as railways and subway
* Process control in refineries and petrochemical facilities
* Gas transmission and distribution network control and water and sewage network control, etc.
Product Introduction:
Remote control and monitoring systems include one or more control centers as controller stations and a number of terminals as controlled stations. Terminals are installed in remote stations and collect the required information and prepare it for the access of the center. This information is recorded and processed in the center and control commands are sent. These commands are received in the terminal and are applied to the controlled systems through interface equipment. RTUs are widely used in industries. Wherever the control of a process is done centrally in one or more control centers, the exchange of information between the center and the process is established through RTUs that are installed at appropriate points and connected to the process.
