Remote Terminal Unit （RTU）

From developing the first set RTU of China in 1982, Dongfang keeps effort in providing customers with more reliable, flexible，stable，and powerful products. With more than 10000 installed RTUs at around 2000 sets of Substation and Feed automation systems, DFE is working to provide more reliable, flexible, stable and economic products.

One unit, multiple capabilities

DF1725IED is a typical example derived from above mentioned target. For its flexible，reliable and stable design, DF1725IED can be used as Gateway, Protocol converter, Centralized RTU,Bay Control Unit and FRTU for transmission and distribution substation,RMU,Pole-top Feeder and other Location to improve the utility’s performance

Unified design is intended to reduce the wiring and maintenance costs. The DF1725IED retrieves data from legacy and third party devices such as relays, transfers it to a host or enterprise system, monitors and runs diagnostics of primary equipment, and expands to meet future physical and functional station requirements.

One solution, various applications

The open architecture of the DF1725IED supports adaptation to different applications. Future functional and quantitative extensions are easy to realize at anytime through hardware or software upgrade for various applications: Transmission automation–- Distribution automation–-Feeder automation—Smart grids.

The DF1725IED allows one substation hardware device to be configured for many different functions by adding software modules. New software modules are being frequently released to further enhance the DF1725IED’s functionality. These new modules can be easily downloaded into the flash memory.
