The GE D20 EME is a General Electric(GE)Ethernet/memory expansion board designed for the GE Multilin D20 and D200 series substation controllers.The following is a detailed description:
Product Type:Ethernet and memory expansion module.
Features:
Ethernet Connection:Requires use with a Media Interface Card(MIC).Supports 10Base-T,10Base-2,and 10Base-Fl Ethernet formats(depending on the MIC model).Connector types include RJ45,BNC,and ST.This allows the D20/D200 controller to seamlessly connect to the substation’s local area network(LAN)or wide area network(WAN),enabling efficient data exchange and remote management with intelligent electronic devices such as SCADA systems and remote control terminals(RTUs).
Memory Expansion:Standard memory is 8MB,expandable to 16MB,providing the foundation for the controller to run more complex applications,store more historical data,and handle larger communication tasks.Communication Ports:Features seven RS-232/485 serial ports,one RS-232 maintenance port,and two D20 Link HDLC ports for communication with D20 I/O modules.
Protocol Support:Supports multiple industrial communication protocols,including DNP 3,Modbus,and IEC 61850,facilitating integration with other devices.
Compatible:Compatible with single-and multi-slot configurations of the D20 and D200 chassis,adapting to various system architectures.
Reliable:Featuring a rugged construction,it is shock and vibration resistant,operates within a-20°C to 60°C temperature range,and complies with EN 61000-6-2(Generic Immunity-Industrial)and EN 61000-6-4(Generic Emissions-Industrial)standards,making it suitable for harsh industrial environments.Physical Specifications:Approximately 482.6mm(width)×133.35mm(height)×205.74mm(depth).
Power Requirements:Integrated into the D20/D200 system.
Applications:Primarily used in substation automation and remote terminal units(RTUs),it can be used as a remote I/O module in SCADA systems to connect to field devices for data acquisition,storage,and monitoring,expanding the network connectivity and data storage capabilities of the D20/D200 system.
