Working Principle
The T3300 chassis provides the physical and electrical foundation for the Regent I/O subsystem. The backplane distributes DC power to all module slots and provides parallel data paths for I/O data exchange between modules and the controller. Each slot is electrically connected to the system power supply and communication bus. The chassis metalwork provides electromagnetic shielding and mechanical protection for the sensitive electronic modules installed within.
Installation Requirements
- Mount in a standard 19-inch industrial rack using appropriate mounting hardware
- Ensure adequate clearance for front module insertion and rear cable access
- Connect system ground to the chassis grounding stud
- Install the chassis in a location with adequate ventilation
- Connect the +15 V DC power supply to the chassis power input
Operating Precautions
- Do not operate the chassis with empty slots unless blank modules are installed
- Ensure all modules are fully seated in the backplane connectors
- Maintain proper cabinet ventilation to prevent overheating
- Verify power supply capacity before fully loading the chassis
- Inspect backplane connectors for damage before installing modules
- Keep the chassis interior clean and free of debris
