GE IC698CHS009A: 9-Slot Universal Backplane for RX3i PACSystem

Product Description

The GE IC698CHS009A is a universal 9-slot backplane (chassis) for the GE (now Emerson) RX3i PACSystem. This component serves as the foundational hardware platform, providing the physical mounting slots, electrical power distribution, and the high-speed PCI-based data bus for all other controller modules. The GE IC698CHS009A allows for the assembly of a medium-sized controller by accommodating a mix of CPU, power supply, I/O, and communication modules in any of its nine universal slots. Its robust construction ensures reliable electrical connectivity and mechanical stability in demanding industrial environments, making it a critical piece of infrastructure for building a scalable and reliable automation controller.

Advantages and Features

The primary advantage of the GE IC698CHS009A is its flexibility within a compact form factor. The universal slot design allows system designers to customize the controller layout without being constrained by dedicated slots for specific module types, optimizing the use of available space. The PCI bus provides a high-bandwidth, deterministic data pathway, which is essential for fast and reliable real-time control applications. The backplane is engineered for durability, with a sturdy design that protects the critical bus connections from vibration and ensures long-term reliability. The GE IC698CHS009A offers a balanced solution, providing more expansion capability than a micro-PLC while being more space-efficient than the largest RX3i or RX7i chassis.

Application Cases in Various Fields

This backplane is ideal for mid-sized control applications. In Water and Wastewater Treatment, the GE IC698CHS009A might form the main controller for a treatment process train or a large pump station. Within Manufacturing, it could serve as a cell controller for a complex assembly or packaging line, housing the necessary I/O and communication cards. For Oil & Gas, it might be used in skid-mounted control systems for compressors or separators. It is also well-suited for HVAC Control in large commercial buildings and for Material Handling systems of moderate scale.

Comparisons with Competing Products

Compared to fixed I/O PLCs or smaller modular systems, the GE IC698CHS009A offers superior expandability and performance. Competing products include backplanes/chassis from Allen-Bradley (CompactLogix 1769-A9) or Schneider Electric (Modicon M580 BMEXBP0900). The GE IC698CHS009A is distinguished by its use within the RX3i platform, which is known for its strong performance in both discrete and process applications and its migration path from older GE Series 90-70 systems. Its universal slot design offers more configuration freedom than some competing systems that have reserved slots for power supplies or CPUs.

Selection Suggestions and Precautions

1. Power Supply Selection and Placement: The GE IC698CHS009A requires a compatible RX3i power supply module (e.g., IC698PSD350). The power supply must be installed in the correct slot (typically slot 0 or slot 8, as specified in the manual) and must be sized to handle the total current draw of all installed modules.
2. Module Placement Rules: While slots are universal, adhere to the controller’s configuration rules. The CPU module usually has a recommended slot (often slot 1). Ensure high-power or heat-generating modules are spaced appropriately for adequate cooling.
3. Mechanical Installation: Ensure the GE IC698CHS009A is securely mounted to a solid surface using all provided mounting points to prevent flexing and ensure good electrical grounding. Proper grounding is essential for noise immunity.
4. Static Handling: The backplane contains sensitive bus circuitry. Always handle it with proper electrostatic discharge (ESD) precautions. Avoid touching the edge connector fingers.
5. Planning for Future Expansion: When populating the GE IC698CHS009A, consider leaving one or two slots open for future expansion or additional communication interfaces. Document the slot assignment of every module meticulously in the system documentation for future maintenance and troubleshooting.
