ABB GDD471A001
Product Overview
ABB GDD471A001, order number 2UBA002322R0001, is a GDD (Gateway Data Device) communication gateway module developed for ABB Procontrol P and Symphony Plus DCS platforms. It acts as a protocol bridge, realizing data exchange between the internal rack bus of Procontrol P control rack and external fieldbus networks including Profibus DP and Modbus RTU.
This module enables legacy turbine control and process control systems to communicate with modern SCADA, 800xA system or third-party PLC equipment without major reconstruction of original I/O racks. It adopts rack insertion installation, with galvanic isolation between internal bus and fieldbus side, effectively suppressing electromagnetic interference in power station environments. Built-in status and fault LED indicators help field engineers quickly locate communication failures. It is widely used for spare replacement and system upgrade of old power plant turbine control cabinets.
