I/O modules

This bus expansion cable extends the I/O network for GE Fanuc Series 90-30 control systems. The IC693CBL300 connects the base CPU rack to remote expansion racks easily. It carries both power and communication signals between the main and expansion chassis. System integrators use this cable to distribute I/O across multiple cabinets and locations. Its rugged construction ensures reliable data transmission in industrial environments.

Technical Specifications Summary

Mechanical Design and Cable Construction

The cable features a 20-conductor flat ribbon design with overall foil shielding. Each conductor uses 28 AWG stranded copper wire for flexibility and durability. The shielding protects communication signals from electromagnetic interference effectively. A drain wire provides a convenient grounding point for the shield. The cable diameter measures 12.5 millimeters for easy routing through cable trays. Its minimum bend radius of 50 millimeters accommodates tight corners and compact installations. The flat design allows neat stacking and bundling within control cabinets. This construction ensures signal integrity over the cable’s entire service life.

Connector Specifications and Interface

Both ends of the IC693CBL300 terminate with 50-pin D-sub connectors. These connectors match the expansion ports on the CPU and expansion racks precisely. The pin configuration follows the standard GE Series 90-30 bus architecture. Each connector features threaded retaining screws for secure attachment. This design prevents accidental disconnection due to vibration or maintenance activities. The connectors include strain relief boots to protect wire terminations from stress. Gold-plated contacts ensure low resistance and corrosion resistance over time. These connectors withstand 500 insertion and removal cycles without performance degradation.

Bus Extension and System Configuration

This cable enables seamless bus extension from the base CPU to remote racks. It transfers both the proprietary GE Genius bus and power signals simultaneously. Users can place the expansion I/O rack up to 1.0 meter from the main CPU. This distance covers typical applications within a single control cabinet. For longer distances, multiple cables can daisy-chain to additional racks. The IC693CBL300 maintains the high-speed bus communication without introducing delays. It preserves the scan cycle timing and deterministic performance of the system. Consequently, expansion racks operate as an integral part of the controller architecture.

Signal Integrity and Shielding Performance

Industrial environments contain motors, drives, and other noise sources constantly. The cable’s foil shield provides excellent protection against electromagnetic interference. It attenuates both radiated and conducted noise to maintain signal quality. The drain wire allows easy connection to protective earth ground at both ends. This grounding scheme diverts induced noise away from communication signals effectively. The twisted-pair arrangement within the cable further reduces crosstalk between conductors. These features ensure error-free data transmission even in harsh industrial settings. The IC693CBL300 delivers reliable bus communication regardless of operating conditions.

Environmental Durability and Installation

The cable operates reliably across a broad temperature range from 0 °C to 60 °C. Storage temperatures extend from -30 °C to 80 °C for transportation and warehousing. The outer jacket resists oil, grease, and common industrial chemicals. This resistance makes the cable suitable for machine tool and process plant environments. Installation requires simply connecting both ends to the appropriate rack ports. The flat cable design facilitates routing through cabinet wire ducts and raceways. Cable ties and adhesive clips secure the cable neatly in any installation.
