GE D20 EME 10BASE-T High Performance Motion Control Module

Description

The GE D20 EME 10BASE-T is an Ethernet media interface card designed for GE’s D20 and D200 series substation controllers, commonly used in utility automation and remote terminal unit (RTU) environments. This module primarily serves to provide reliable Ethernet communication through the 10BASE-T standard, supporting data rates of 10 Mbps. It enables seamless integration of D20 and D200 chassis systems into Ethernet networks, facilitating real-time data exchange essential for substation automation, protective relaying, and monitoring applications. The D20 EME 10BASE-T finds its use in electrical utilities, industrial plants, and infrastructure requiring high availability and robust network connectivity for control and monitoring.

This module integrates into the D20 and D200 chassis as a media interface card, expanding the system’s communication capabilities beyond serial links to include Ethernet-based connectivity. By supporting 10BASE-T Ethernet, the D20 EME 10BASE-T enhances the versatility of these controllers, enabling remote monitoring and control through modern IP-based networks. The card installation is via standard card insertion in the chassis backplane, compatible with both single-slot single-processor and multi-slot multiple processor configurations offered by the D20 and D200 platforms. Memory and processing capacity are typically expanded alongside, with this module supporting system memory upgrades from 8MB to 16MB, fortifying overall system performance for complex automation tasks.

Technically, the GE D20 EME 10BASE-T operates within an ambient temperature range of -25°C to 70°C. The board is designed for industrial-grade reliability and features LED status indicators for network activity and fault diagnosis. Its compact form factor (dimensions approximately 110 mm x 60 mm x 35 mm) allows installation within the confines of standard control chassis. The interface supports multiple Ethernet standards, including 10BASE-T, 10BASE2, and 10BASE-FL in some variations, to cater to different network topologies and infrastructure requirements. This adaptability ensures that the D20 EME 10BASE-T can be deployed effectively in both new setups and retrofitted in existing operational environments. The board also supports seamless integration with multiple digital input/output modules, facilitating scalable and flexible system architecture.

The D20 EME 10BASE-T works in concert with GE’s other modules such as the D20ME main processor, D20 I/O modules for digital and analog signals, and optional communication interface cards to create a cohesive, scalable automation solution tailored to utility and industrial needs.

Installation requires careful insertion into the compatible D20 or D200 chassis, ensuring firm seating and proper connection to backplane contacts. The network cabling should follow Ethernet standards for shielding and grounding to minimize interference. Periodic visual inspection of indicator LEDs and physical connections helps maintain reliable operation. Firmware and software updates provided by GE should be applied during maintenance intervals to ensure optimal compatibility and security.
