Description
1. Product Description
The GE Fanuc IC660ELB912 is a high-performance μGENI Network Interface Board designed for industrial automation systems, part of the Genius I/O product family. Engineered as a daughterboard for microprocessor systems, the IC660ELB912 enables seamless communication between host controllers (e.g., IBM PC/AT/XT) and the Genius I/O bus, supporting remote I/O control and data exchange. It handles all data transfers, freeing the host to manage critical tasks while leveraging the Genius I/O’s reliability and noise immunity. With support for up to 30 bus devices and configurable baud rates (38.4K, 76.8K, 153.6K standard/extended), the module maintains real-time data images of connected devices and facilitates communication via global data, datagrams, and directed control messages. Its dual-port RAM architecture ensures efficient data sharing between the 6303 microprocessor (message handling) and 64180 manager microprocessor (system control). The IC660ELB912 is ideal for distributed control systems in manufacturing, energy, and process industries, offering robust connectivity and diagnostic capabilities.

6. Selection Recommendations
- Compatibility: Ensure compatibility with your PCIM (single/double-slot) and host CPU (e.g., IBM PC/AT/XT).
- Device Count: Match the number of remote I/O devices (up to 30 per board).
- Baud Rate: Choose baud rate based on network distance and data volume (higher rates for shorter distances).
- Power Budget: Account for current consumption (1.0–1.5 A) in system power design.
- Space Constraints: Verify mounting space (1/8-inch clearance) and airflow requirements.
7. Precautions
- Installation: Use spacers/screws for secure mounting; avoid adhesive products. Maintain 1/8-inch clearance for airflow.
- Power Stability: Use a stable 5V DC supply to prevent logic errors.
- Configuration: Set DIP switches for baud rate and device addressing per the manual.
- Redundancy: Deploy dual boards in critical systems for fault tolerance.
- Firmware Updates: Regularly update firmware via GE Fanuc/Emerson tools for compatibility and security.
