Description
Foxboro RH916FL
Technical Specifications
- Base Model: RH916 Series 16-Slot Horizontal Backplane.
- Revision Identifier: FL.
- Slot Configuration: 16 slots for Series 200 FBMs.
- Bus Type: 2 Mbps Redundant HDLC Fieldbus.
Functional Features
- Revision Specificity: Guarantees exact mechanical and electrical compatibility with existing system backups and spare parts inventories.
- Mixed Module Support: Allows standard and redundant FBM modules to be installed in any slot.
- Online Expansion: Supports adding new baseplates to the fieldbus without shutting down the system (in redundant configurations).
Application Scenarios
Ideal for spare parts procurement, system expansions, or direct replacements in plants where maintaining a consistent hardware revision level is critical for minimizing integration risks.
Performance Parameters
- Electrical Specs: Identical to standard RH916 series backplanes.
- Mechanical Dimensions: Same footprint as RH916DE.
Material Composition
Industrial-grade PCB materials and connectors, consistent with Foxboro’s high-reliability standards.
Structural Characteristics
Mechanically identical to other RH916 horizontal backplanes. The “FL” revision is clearly marked on the product label for asset management.
Working Principle
Operates identically to the base RH916 platform, providing passive power distribution and fieldbus communication routing.
Installation Requirements
Follow standard RH916 installation guidelines. Verify that the system software recognizes this specific hardware revision.
Usage Precautions
Do not mix different backplane revisions in the same redundant fieldbus segment unless validated by the manufacturer. Always de-energize the baseplate before installing or removing modules if hot-swap is not supported by the specific FBM type.
