GE IC698CHS009A

Description

Product Description

GE IC698CHS009A is a VME-based rack or chassis, serving as the foundational hardware platform for the GE Fanuc Series 90-70 PLC system, also marketed as the RX7i. This component, the IC698CHS009A, is not a programmable module but the critical physical backbone that houses and interconnects all other system components. Its primary function is to provide the mechanical structure, the high-speed VME backplane for data exchange, and the regulated power distribution to the CPU, I/O, and communication modules. The selection of the correct chassis, such as the GE IC698CHS009A, is the first and most fundamental decision in building a 90-70 system, as it determines the total number of modules that can be installed, the power supply requirements, and the system’s physical footprint. The reliability and integrity of the entire PLC system depend on a robust and properly configured chassis like the IC698CHS009A.

Product Parameters / Technical Specifications

• Manufacturer: GE Fanuc (now part of Emerson)
• Series: Series 90-70 / RX7i PLC System
• Functional Designation: Main Rack / Chassis
• Form Factor: Standard 19-inch rack-mount enclosure.
• Backplane Type: VME (Versa Module Eurocard) bus.
• Number of Slots: Contains a specific number of slots for modules (e.g., 5, 9, or 17 slots total). The model “009A” typically indicates a chassis with slots, often a 9-slot configuration.
• Power Supply Integration: May include an integrated power supply or have slots for plug-in power supply modules (like the IC698PSAxxx). The exact configuration is defined by the chassis model suffix.
• Input Power: Accepts AC or DC input power, specified for the chassis model, which is then distributed to the modules via the backplane.
• Cooling: Includes fans or provisions for airflow to cool the installed electronic modules.
• Communication Ports: The chassis itself does not have communication ports; these are provided by modules installed in its slots.

Advantages and Key Features

• High-Speed VME Backplane: Provides a deterministic, high-bandwidth data pathway between the CPU, I/O processors, and communication cards, which is essential for large, fast, and complex control applications.
• Robust Mechanical Construction: Built as a heavy-duty industrial enclosure designed to withstand vibration and provide reliable operation in harsh environments.
• Modular and Scalable: The slot-based design allows for flexible system configuration. The GE IC698CHS009A can be populated with a mix of CPUs, discrete/analog I/O, special function modules, and network interfaces to meet exact application needs.
• Integrated Power Management: Designed to work seamlessly with compatible GE power supplies, providing clean, regulated power to all modules and often supporting N+1 redundant power configurations for high availability.
• Hot-Swap Capability (in configured systems): When used with a compatible redundant CPU and power system, modules in the chassis can often be replaced without powering down the entire control system.
• Proven Legacy Platform: The 90-70/RX7i platform, anchored by chassis like the IC698CHS009A, is known for its extreme ruggedness and reliability in demanding industrial sectors.

Application Cases in Industry

• Large Process Automation: Serves as the main controller rack in chemical plants, oil refineries, and pharmaceutical facilities where high I/O counts and complex regulatory control are required.
• Power Generation (Balance of Plant): Used for controlling critical auxiliary systems such as coal handling, ash removal, water treatment, and flue gas desulfurization.
• Metals Production & Rolling Mills: Provides the high-speed processing and deterministic scan times needed for controlling rolling mills, furnace charging, and continuous casting lines.
• Material Handling Mega-Systems: Forms the core of control systems for large airport baggage handling networks, automated storage/retrieval systems (AS/RS), and parcel distribution centers.

Selection Suggestions and Precautions

1. Determine Required Number of Slots: Carefully count all modules needed (CPU, power supply, I/O, comms, special function) and select a chassis like the GE IC698CHS009A with sufficient slots. Always leave room for future expansion.
2. Verify Power Supply Configuration: Determine if the IC698CHS009A has an integrated power supply or requires separate plug-in power supply module(s). Ensure the total power capacity meets the sum of all module requirements.
3. Check Compatibility with Existing Modules: If this is a replacement or expansion, ensure all existing Series 90-70 modules are compatible with this specific chassis model. Consult the hardware compatibility guide.
4. Consider Redundancy Needs: For critical applications, select a chassis model and configuration that supports redundant power supplies and, if needed, a redundant CPU pair.
5. Environmental Factors: Ensure the chassis’ environmental specifications (temperature, humidity) are suitable for its intended location (e.g., inside a conditioned control room vs. a field cabinet).
6. Legacy Sourcing Strategy: The Series 90-70 is a discontinued platform. When sourcing a GE IC698CHS009A, work with specialized surplus dealers who can verify the condition of the backplane, connectors, and cooling fans. Consider the long-term maintenance plan for the entire system.
