As the compact protocol gateway for system integrated application, DGW-A2/A4 is designed in conformity with the new IEC 61850 standards. It can be anywhere deployed to be a smart unit to transfer data by its RS232/RS485 serial ports and Ethernet ports. By importing any prespecified IEC 61850 SCL (.icd/.cid) template file and after mapping the data to internal VMD model with the configuration tool – ICE, this unit can be viewed just as the standard IEC 61850 IED from the master station.
With powerful data communication and process function, high reliability, low power consumption, flexible and easy installation advantages, DGW-A is the ideal intelligent device choice for all kinds of system integrated applications.
