GE Multilin Industrial Control Communication and I/O Architecture
The GE Multilin F650-B-F-M-F-1-G-0-HI-6-E integrates Ethernet communication, programmable logic, and distributed I/O processing for substation automation tasks. The relay exchanges protection data through IEC 61850 Edition 2 messaging and supports GOOSE communication for high-speed interlocking and control applications.
Furthermore, the F650 hardware architecture supports deterministic communication paths between protection elements, breaker control circuits, and external SCADA systems. The integrated I/O expansion configuration provides 16 digital inputs and 8 relay outputs for direct connection to field devices and switching equipment.
The relay processes electrical measurements from current and voltage inputs, then applies protection algorithms including instantaneous overcurrent, time overcurrent, directional elements, and frequency-based load shedding logic. Therefore, it can execute trip commands and control actions based on configured protection settings.

Field Installation Guidelines
- Install the GE Multilin F650 relay inside a suitable protective control cabinet with appropriate ventilation and environmental protection.
- Verify auxiliary power polarity and voltage range before energizing the relay.
- Connect communication cables according to the selected Ethernet or serial network architecture.
- Separate protection signal wiring from high-voltage power conductors to reduce electromagnetic interference.
- Use shielded communication and signal cables where required by the substation grounding design.
- Confirm current transformer and voltage transformer wiring polarity before commissioning protection functions.
- Verify digital input contact wiring and relay output circuits before applying trip or breaker control commands.
- Perform configuration validation, communication testing, and protection function checks before placing the relay into service.
