ICS Triplex T8131 TMR Expander Processor Module

The ICS Triplex T8131 Expander Processor Module strengthens multi-chassis Trusted architectures by linking the Expander Bus with the Expander Chassis backplane. Engineers use the T8131 to extend system capacity while maintaining high-bandwidth IMB communication and robust fault containment. The module supports rapid diagnostics, hot replacement, and automatic recovery strategies, which greatly enhance availability in safety-critical control systems.

Reliable Multi-Chassis Integration

The T8131 operates with full TMR 3-2-0 fault tolerance, and it leverages hardware-implemented HIFT technology to maintain deterministic performance during abnormal conditions. It coordinates data exchange across UTP cabling or fiber interfaces, offering flexible expansion distances while preserving system synchrony. Clear front-panel indicators simplify real-time health monitoring during commissioning and maintenance.
