Description
GE IC698CHS217 Technical Specifications:
- Slot Count: 17 slots.
- Backplane: High-speed serial backplane.
- Compatibility: Fully compatible with all PACSystems RX7i CPUs and I/O modules.
- Power Distribution: Full RX7i voltage rail support.
Functional Features:
- Serial Backplane Architecture: Ensures high-speed, deterministic module-to-module communication.
- Modular Expansion: Supports daisy-chaining with additional expansion racks via universal backplane modules.
- Tool-less Module Removal: Ergonomic design allows for easy module extraction using integrated ejectors.
- EMI Shielding: Conductive chassis design minimizes electromagnetic interference.
Application Scenarios:
- Expansion racks for large distributed control systems.
- Dedicated I/O racks located remotely from the main CPU rack.
- Panel builds requiring specific chassis revisions for OEM compliance.
Performance Parameters:
- Data Integrity: Error-checking protocols on the serial backplane ensure reliable data transmission.
- Thermal Performance: Optimized airflow path from front to rear of installed modules.
- Mechanical Life: Backplane connectors rated for hundreds of insertion/extraction cycles.
- Compliance: Meets CE, UL, and CSA industrial control standards.
Material Composition & Structural Characteristics:
- Enclosure: Ruggedized steel chassis with anti-fingerprint coating.
- Backplane PCB: Multi-layer FR4 board with controlled impedance traces.
- Hardware: Stainless steel mounting screws and captive hardware.
- Labeling: Clear slot numbering and module orientation indicators.
Working Principle: Functions identically to the standard RX7i chassis, providing the physical and electrical interconnect for the control system. The serial backplane replaces traditional parallel addressing with packet-based communication, allowing for higher bandwidth and future scalability without hardware changes.
Installation Requirements:
- Expansion Cabling: If used as an expansion rack, connect to the main rack using approved RX7i universal backplane cables.
- Termination: Install backplane termination modules if required by the system configuration.
- Grounding: Ensure chassis ground is bonded to the panel ground plane.
- Labeling: Clearly label the rack as an expansion chassis for maintenance clarity.
Usage Precautions:
- Cable Routing: Route expansion cables away from high-voltage wiring to prevent noise injection.
- Module Compatibility: Verify that all installed modules are rated for the RX7i serial backplane.
- Power Supply Sizing: Ensure the power supply in this rack (if locally powered) is adequately sized for the local load.
- Handling: Handle the chassis by the edges; avoid touching backplane connectors.
