Description
Foxboro FCP280RH924WA
Technical Specifications
- Series: FCP280 (High-Performance).
- Revision: RH924WA.
- Architecture: Dual-core redundant processing.
- Network: 100 Mbps Redundant Fiber Ethernet.
Functional Features
- Enhanced Processing: Faster cycle times and higher block capacity for complex model predictive control (MPC) and advanced regulatory control.
- Advanced Fault Tolerance: Improved synchronization algorithms for near-zero bumpless transfer during failover.
- Expanded I/O: Supports higher densities of Series 200 FBMs and high-speed communication modules.
Application Scenarios
Critical safety-related loops, large-scale refinery units, and processes where even momentary control interruption is unacceptable.
Performance Parameters
- Failover Time: < 100 ms (typically much faster).
- Memory: Expanded RAM/Flash compared to FCP270.
- Environmental: G3 Harsh Environment certified.
Material Composition
Premium industrial components with extended temperature ratings. Enhanced shielding for high-noise environments.
Structural Characteristics
Slightly larger or denser packaging than FCP270 to accommodate enhanced electronics. Distinct RH924WA labeling for precise spare parts management.
Working Principle
Operates in a lock-step or hot-standby mode where both processors validate outputs before transmission. Utilizes advanced voting logic to isolate faults instantly.
Installation Requirements
Requires compatible baseplates and power supplies capable of handling the slightly higher power draw. Fiber optic redundancy must be correctly wired.
Usage Precautions
Ensure the control software is licensed for FCP280 features. Perform regular redundancy tests to validate failover performance.
