Technical Architecture & Functional Positioning

The F650-B-F-D-F-2-G-1-HI-6E is positioned as a high-density, multi-object bay controller and protection IED for medium-voltage distribution and industrial substations. Within the substation automation hierarchy, it sits at the bay level, combining traditional hard-wired protection with modern process-bus and station-bus capabilities.

GE adopted a dual-processor architecture: a high-performance 32-bit CPU handles protection algorithms and sampled-value processing, while a dedicated communication processor manages IEC 61850 MMS, GOOSE, and SV streams with zero added latency. The ability to subscribe directly to IEC 61850-9-2 LE sampled values eliminates copper CT/VT wiring in digital substations, reducing installation cost and improving safety through arc-flash mitigation.

The “6E” suffix indicates dual fiber-optic 100Base-FX ports plus redundant copper Ethernet, enabling native PRP/HSR redundancy without external switches. This is critical for ring-main units and critical process feeders where network availability must exceed 99.999 %.
