      The D20 ME is a multi-functional remote terminal unit (RTU) and substation automation platform widely used in power transmission and distribution systems. Its primary function is to acquire real-time data from field devices such as protective relays, meters, circuit breakers, and sensors, and transmit this information to a Supervisory Control and Data Acquisition (SCADA) system. The D20 ME supports multiple communication protocols, enabling seamless interoperability with both traditional and modern substation equipment while ensuring high reliability and deterministic performance.

      In addition to data acquisition, the D20 ME provides advanced control, automation, and event management capabilities in substation environments. It can execute logic-based control schemes, record event sequences with high time resolution, and support remote switching operations. Its modular architecture allows for flexible expansion of I/O modules and communication interfaces, making it suitable for complex power grid infrastructures with extremely high requirements for scalability, network security, and continuous operation.

      The D20 ME General Electric Substation Controller Motor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      General Electric D20 ME Substation Controller Motor datasheet(manual), Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
      Field signals (including analog and digital signals) are acquired through input modules, conditioned, and converted into digital data for internal processing. The onboard processor executes firmware-based control logic, evaluates status conditions, and manages communication tasks. Processed data is transmitted to a higher-level SCADA or energy management system via supported communication protocols. Simultaneously, control commands from remote systems are verified and sent to field devices. This bidirectional data and control flow ensures reliable monitoring, protection coordination, and automated operation of the substation.

      FAQ

      View All Faqs
      • What architectural framework underpins the computational and communication capabilities of D20 ME within modern substation automation systems?
        The D20 ME is engineered as a modular Remote Terminal Unit (RTU) platform designed to integrate data acquisition, protocol conversion, and supervisory control functions. Its architecture combines embedded processing resources, configurable I/O subsystems, and multi-protocol communication interfaces to support mission-critical utility infrastructure.
      • How does D20 ME achieve deterministic data acquisition and real-time telemetry transmission in latency-sensitive power system environments?
        The D20 ME employs time-synchronized sampling mechanisms, buffered data management, and prioritized communication scheduling. These capabilities ensure accurate event capture, minimal transmission delay, and reliable SCADA reporting even during high network traffic conditions.
      • In what manner does D20 ME facilitate interoperability across heterogeneous communication protocols in utility networks?
        The D20 ME supports a broad spectrum of industry-standard protocols, enabling seamless integration between Intelligent Electronic Devices (IEDs), control centers, and legacy infrastructure. Its embedded protocol conversion engine allows translation between field-level communication standards and supervisory network requirements.
      • Why is the modular I/O scalability of D20 ME advantageous for evolving substation and distribution automation architectures?
        The D20 ME is designed with expandable input/output modules that allow incremental system growth without disrupting existing operations. This modularity supports flexible configuration of analog, digital, and pulse inputs to accommodate diverse field instrumentation requirements.
      • How does D20 ME ensure cybersecurity resilience in critical infrastructure deployments?
        The D20 ME incorporates role-based access control, encrypted communication pathways, and secure authentication mechanisms. These cybersecurity features mitigate unauthorized access risks while preserving the integrity and confidentiality of operational data.
      • How does D20 ME contribute to disturbance recording and event-driven automation within power system operations?
        The D20 ME supports high-resolution event logging, sequence-of-events recording, and time-stamped data capture. These capabilities enable accurate post-event analysis, rapid fault localization, and improved operational decision-making.
