GE Fanuc IC200GBI001-GJ Versamax Genius Network Interface Unit
The GE Fanuc IC200GBI001 (Part Number: IC200GBI001-GJ) is a high-performance Genius Network Interface Unit (NIU) within the Versamax PLC family. It is specifically engineered to interface Versamax I/O modules with a Genius bus network, allowing the rack to operate as a distributed intelligent slave. The IC200GBI001 manages all data exchange between the local I/O modules and a master controller, such as a Series 90-70, PACSystems RX3i, or RX7i, providing a seamless bridge for remote I/O processing.
This interface unit is distinguished by its support for dual Genius bus terminals, enabling redundant cabling topologies that are essential for mission-critical applications where network uptime is paramount. By utilizing the IC200GBI001-GJ, engineers can deploy up to 8 expansion racks (a total of 64 modules) per Genius network node, maximizing I/O density while maintaining high-speed deterministic communication. The unit handles complex signal conditioning and diagnostics locally, reporting status through its comprehensive LED array and back to the host controller via the Genius protocol.
