Technical Architecture & Functional Positioning

The F650-B-F-G-F-2-G-4-HI-E is engineered specifically for digital substations and high-availability industrial networks. The “G” in position 3 and 6 denotes full redundant fiber-optic Ethernet (two 100Base-FX + one copper), eliminating single points of failure in station-bus and process-bus communications. The “4” board option adds high-accuracy demodulated IRIG-B plus PPS, mandatory for synchrophasor applications and precise sequence-of-events timing across the substation.

Dual-DSP architecture separates protection-critical sampled-value processing from communication stacks, guaranteeing deterministic <1 cycle protection response even under full IEC 61850 traffic load. Direct subscription to two independent 9-2 LE streams allows complete copper-free installations when paired with GE Brick or third-party merging units.
