GE Fanuc D20-EME 10BASE-T High-Performance Industrial Communication Module
The GE Fanuc D20-EME 10BASE-T is a 10 Mbps Ethernet interface module designed for GE’s PACSystems RX3i platform, specialized in industrial automation and substation control. Engineered with a 32-bit PowerPC processor and D.20 HDLC communication ports, this module enables seamless integration of legacy systems with modern industrial networks, ensuring reliable operation in extreme environments.
1. Product Overview
The D20-EME 10BASE-T serves as a critical component in GE’s PACSystems RX3i architecture, providing 10 Mbps Ethernet 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.
