Description
GE IC693CHS391 Technical Specifications:
- Rack Type: 10-Slot Expansion Rack
- System Compatibility: GE Fanuc Series 90-30
- Slot Count: 10 standard module slots
- Backplane: Passive backplane with 5V DC and 24V DC power buses
Functional Features:
- Modular Expansion: Allows users to add up to 10 additional modules to a PLC system.
- Power Distribution: Distributes backplane power from the power supply to all installed modules.
- Data Bus: Provides the parallel data bus for high-speed communication between the CPU and I/O modules.
Application Scenarios:
- Systems requiring more I/O points than the base rack can accommodate.
- Separating high-noise I/O modules from the CPU rack.
- Custom machine builds with specific module layouts.
Performance Parameters:
- Backplane Current: Rated for specific 5V and 24V current capacities (check power supply sizing).
- Slot Pitch: Standard Series 90-30 module width.
Material Composition & Structural Characteristics:
- Frame: Heavy-duty metal chassis with DIN rail mounting capability.
- Backplane: Multi-layer PCB with gold-plated edge connectors.
- Grounding: Dedicated grounding stud for chassis and signal ground.
Working Principle: The rack acts as a passive interconnect. The power supply injects voltage onto the backplane power rails, while the CPU communicates with modules via the parallel data traces on the backplane PCB.
Installation Requirements:
- Mounting: Securely mount on a DIN rail or panel using provided hardware.
- Power Supply: Ensure the installed power supply can handle the total backplane current draw of all modules.
- Grounding: Connect the rack ground stud to a clean earth ground.
Usage Precautions:
- Slot Allocation: Plan module placement to ensure adequate ventilation and avoid placing high-heat modules adjacent to sensitive analog modules.
- Backplane Connectors: Handle modules carefully to avoid bending the backplane edge connector pins.
- Expansion Limits: Verify the maximum number of expansion racks supported by the specific CPU model.
