ICS TRIPLEX T8310 Trusted TMR Expander Processor

The Rockwell T8310 Trusted® TMR Expander Processor Module is a critical component for extending the Trusted control system’s capabilities. It integrates with the Trusted Expander Chassis, serving as the interface between the Expander Bus and the Expander Chassis Backplane. Utilizing Unshielded Twisted Pair (UTP) or Fiber Optic connections, it ensures fault containment and system reliability, adhering to the Trusted system’s fault-tolerant, high-availability design.

Key Features

TMR Fault Tolerance: Operates with a 3-2-0 fault-tolerant configuration using HIFT (Hardware Implemented Fault Tolerant) architecture.
Diagnostics and Fault Handling: Features hardware/software testing for fast fault detection and response.
Hot Replacement: Supports online replacement without disturbing system operations.
Front Panel Indicators: Displays health and operational status.
Modular Configuration: Supports automatic/manual repair strategies for enhanced system availability.
