RCS 9782 Intelligent Gateway
Application
RCS-9782 intelligent gateway is a communication conversion device developed for substation automation system and used for message transferring between bay-level WorldFIP fieldbus and station-level Ethernet. In the bay level, WorldFIP fieldbus is used for communication with protection device, bay control units, and other IEDs, acquisition of various protections, measuring and control information, and send the information to station control level equipments via network. WorldFIP fieldbus is a fast, reliable and interference resistant fieldbus and has performance in various aspects far better than serial ports and some other fieldbus. Application of RCS-9782 gateway can greatly increase communication speed between bay level equipments and station level’s.
Typical application of RCS-9782 gate way is dual gateway operating mode (1 on duty, 1 standby).
Standard types of communication interface provided by this device include WorldFIP, 100FX-SC and RJ-45.
Device Structure
RCS-9782 gateway is standard 1U chassis structure and adopts DC power supply. The core of the device consists of 2 high-performance 32-bit embedded processors.
