GE Digital Energy G500 – Advanced Multi-Function Controller Platform


GE’s Multilin G500, a member of the advanced Multi-function Controller Platform (MCP), offers a high capacity, secure, future-proof, and substation-hardened set of modular and scalable hardware and software components designed to simplify the deployment, operation and maintenance of automation systems.

This advanced hardware platform makes it it possible for a single device to host multiple functions and applications such as Supervisory Control and Data Acquisition (SCADA) Concentrator, Remote terminal Unit (RTU), Human Machine Interface (HMI), advanced cyber security features, and non-operational data storage. By these functions, substation operators can reduce the cost of deployment and operation while increasing system reliability through a reduced number of devices in the system.

The G500 is designed to provide a reliable and accurate collection of data (metering, status, events and faults) from serial or LAN-based intelligent substation devices to master applications such as SCADA, EMS, DMS, DCS or other enterprise applications. With its modern and robust cyber security features, the G500 is designed for smooth integration into NERC CIP and Cyber Security environments while consolidating functions such as Ethernet communications, time synchronization, HMI and SCADA applications.

Key Benefits

  • Standardize substation architectures with a cost-effective, IEC 61850-3 compliant platform, scalable for small to large systems with up to 200,000 data points
  • Simplify engineering and operations through consolidation of functions
  • Reduce system cost by eliminating dedicated HMI computers, external Ethernet switches and leveraging the built-in configurable PRP
