GE WESDAC D20ME II Substation RTU Processor Module
The D20ME II (GE WESDAC D20ME) is a main processor module designed for General Electric D20 and D200 substation automation platforms and Remote Terminal Unit (RTU) assemblies. Powered by a Motorola 68030 microprocessor, it executes central processing functions including data acquisition, local control logic, telemetry processing, and SCADA system communication within power utility substations.
Hardware Architecture and Memory Config
The module incorporates an onboard memory architecture comprising 2 MB Flash memory for firmware storage, 1.5 MB SRAM for dynamic system execution, and 512 KB NVRAM for non-volatile parameter retention. It interfaces directly with the D20 backplane / VMEbus architecture to coordinate peripheral I/O cards and system communication.
Communication Interfaces
The D20ME II supports up to 7 serial communication ports depending on hardware variant and board configuration. Serial channels operate primarily over RS-232, with RS-485 interface capabilities available on selected hardware variants for local networking and device integration.
