Engineered for GE Genius I/O Bus Systems
This board manages all communication on the Genius I/O bus network. It provides centralized bus control for the GE IC660CBB902K unit. You will find this controller in Genius I/O based distributed systems. Unlike passive bus couplers, this version actively schedules bus traffic. It handles up to 32 Genius I/O blocks on a single bus segment.

Functional Architecture and Bus Management
This bus control board connects to the PLC backplane on one side. It uses a dedicated communication processor for bus scheduling. You can configure the board as bus controller or monitor only. Moreover, the board includes automatic block detection and configuration. These components identify new I/O blocks without manual addressing. Consequently, the system simplifies installation and reduces setup time significantly.
Installation and Operational Guidelines
The GE IC660CBB902K consumes 1.2A at 5V DC during operation. It scans all 32 I/O blocks within 25 milliseconds. You must install termination resistors at both ends of the bus cable. Always use shielded twisted-pair cable rated for Genius I/O networks. This practice maintains signal integrity over long distances. Furthermore, the board supports redundant bus operation for critical applications. This feature provides automatic failover if the primary bus cable fails.
Physical Characteristics and Environmental Limits
This bus control board has a rugged, industrial-grade PCB with metal bracket. Its moderate 0.95 kg weight reflects the robust construction quality. The layout follows GE standard Genius I/O specifications. Therefore, it fits securely into any Genius I/O rack or compatible PLC backplane. The board includes LED indicators for bus activity and error status. In addition, it maintains stable operation between 0°C and 60°C ambient temperature. You can store this unit safely between -40°C and 85°C.
