Operating System: Foxboro I/A Series proprietary real-time OS
Power: 5V DC and 24V DC from backplane
Form Factor: 6U Eurocard (larger than standard I/O modules)
Operating Temperature: 0 to 60 degrees Celsius
Certifications: UL, CSA, CE, ATEX
Functional Features:
High-Speed Execution: The 32-bit RISC processor with FPU executes complex control algorithms (PID, advanced regulatory control, sequential control) at high speed.
Large Memory: 64MB RAM allows storage of very large applications with thousands of control loops and hundreds of operator display pages.
Dual Redundant Communication: Every processor has two independent communication paths to every I/O module, ensuring no single point of failure.
Processor Redundancy: Supports A/B processor pairs where the backup processor takes over instantly if the primary fails.
Online Diagnostics: Continuous self-testing of CPU, memory, communication, and I/O with automatic fault detection.
Hot Swappable: Can be removed and replaced while the system is running in a redundant configuration.
Fail-Safe Design: All outputs default to a safe state on loss of power or communication.
