Description
Product ParametersThis 32-bit processor features a Freescale 68030 MPU at 40 MHz, with 2 MB Flash memory, 1.5 MB SRAM, and 512 KB NVRAM. It includes 7 programmable RS-232/485 serial ports (up to 38,400 kbps half-duplex), 2 D.20 HDLC ports supporting up to 120 I/O modules with repeaters, plus a maintenance RS-232 port and real-time clock accurate to ±2 ppm.
Datasheet Overview
The datasheet details support for up to 75,000 SCADA points, DNP3/Modbus protocols, and IEC 61131-3 logic for local automation. It lists compatibility with D20 power supplies (20-60 VDC input yielding +5V/7A, +12V/2A outputs) and ANSI/IEEE C37.90 compliance.
General Electric WESDAC D20ME II
Country of Origin
Manufactured in the United States by GE for substation reliability.
Usage Instructions
Install in a D20 VME chassis slot, connect P1/P2 for D.20 links and serial ports to IEDs/SCADA. Configure via GE D20 Base software for protocols, logic, and I/O; power up and verify via maintenance port for relay data and automation like load transfer.
