GE Multilin Industrial Communication and Control Features
The GE Multilin F650GNFBF1G0HICE integrates digital protection processing with substation automation communication. It exchanges protection status, measurement values, and control commands through IEC 61850 based networks and serial communication channels.
Furthermore, the relay supports deterministic industrial communication networks through Ethernet interfaces. The design enables integration with SCADA systems, RTUs, and station controllers while maintaining programmable logic execution for feeder automation schemes.
The F650 platform applies firmware-based configuration management to define protection elements, input/output mapping, and control logic. In addition, the relay supports Profinet / EtherNet-IP style deterministic network concepts used in industrial control environments through Ethernet communication infrastructure.
The relay provides programmable protection and control functions, including:
- Phase instantaneous and time overcurrent protection (ANSI 50/51)
- Neutral and ground overcurrent protection (ANSI 50N/51N, 50G/51G)
- Directional overcurrent protection (ANSI 67P, 67N)
- Voltage protection (ANSI 27/59)
- Negative sequence monitoring (ANSI 46/47)
- Thermal overload protection (ANSI 49)
- Breaker failure protection (ANSI 50BF)
- Automatic reclosing (ANSI 79)
- Frequency protection and rate of change of frequency (ANSI 81/81R)
- Synchronism check (ANSI 25)
