From developing the first set RTU of China in ***2, Dongfang keeps effort in providing customers with more reliable, flexible，stable，and powerful products. With more than ****0 installed RTUs at around ***0 sets of Substation and Feed automation systems, DFE is working to provide more reliable, flexible, stable and economic products.

One unit, multiple capabilities

DF***5IED is a typical example derived from above mentioned target. For its flexible，reliable and stable design, DF***5IED 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 DF***5IED 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 DF***5IED 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 DF***5IED 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 DF***5IED’s functionality. These new modules can be easily downloaded into the flash memory.
