Hardware Architecture Note
Features:
- GFOI (Ground Fiber Optic Interface)
- Isolated 5V DC input logic power loop
- Dual optical fiber ports (dedicated Transmitter Tx and Receiver Rx lines)
The core function of this module is to provide a fully electrically isolated high-speed fiber optic data transmission channel in medium to large-scale industrial automation networks (such as GE's Mark VI/VIe turbine control system or EX2100 excitation system). It can serve as a communication bridge between the control center and remote extended racks, drives, or slave devices, supporting long-distance, high-speed information transmission and can be widely deployed in various complex distributed industrial field environments.
This module integrates dedicated high-speed dual fiber optic ports, typically supporting lossless data throughput of up to 10 Mbps or higher, and seamlessly integrates into GE's own bus communication architecture. It also features comprehensive built-in LED status indicators and field diagnostic mechanisms, enabling real-time monitoring of optical link connectivity, signal strength, and abnormal errors, greatly simplifying the commissioning and subsequent maintenance processes in large industrial settings.
The 31F323G1 General Electric GFOI v5 Control Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Industrial gas turbines and high-power excitation regulators generate significant electromagnetic interference (EMI) during normal operation. Under these conditions, standard copper data cables suffer severe signal attenuation and noise interference.
The 31F323G1 module converts the electrical signals generated by the main processing core into optical pulses. These optical pulses are then transmitted via fiber optic lines to isolation nodes, ensuring zero interference and maintaining high data integrity for critical safety trip commands.
This module serves as the motherboard interface within the chassis. Depending on the specific configuration of your Mark VI control cabinet, it can be directly mounted via brass frame screws and physically locked to auxiliary daughterboards (such as the IS200KSPA signal processing auxiliary card).
