Description
GE Fanuc DS200NATOG3A Network and Terminal Output Gateway Module
The GE Fanuc DS200NATOG3A is a high-reliability communication gateway module designed for GE’s Mark VIe and Mark VIIe distributed control systems (DCS), specializing in industrial automation and substation control. Engineered with multi-protocol support and dual Ethernet redundancy, this module enables seamless integration of legacy systems with modern industrial networks, ensuring stable operation in extreme environments.
1. Product Overview
The DS200NATOG3A serves as a critical component in GE’s turbine control architecture, providing Ethernet/IP, Modbus TCP, and Profibus DP connectivity for real-time data exchange between PLCs, SCADA systems, and field devices. Its D.20 HDLC protocol support allows direct communication with D20 I/O modules, while 7 RS-232/485 serial ports enable integration with legacy equipment like printers and IEDs. With -40°C to +70°C operating range and IP66/67 protection, the module withstands harsh conditions in power plants, oil refineries, and smart grid infrastructure.
