ICS Triplex T8311C Trusted TMR Expander Interface Module

The Rockwell ICS Triplex T8311C is a high-reliability Trusted TMR expander interface module, designed for use in safety-critical industrial applications. It provides seamless communication between the Controller Chassis and Expander Chassis in a Trusted Triplex system.

The T8311C employs a triple modular redundant (TMR) architecture with three independent processors executing identical programs simultaneously. This design ensures continuous fault-tolerant operation even if one processor fails, maintaining system safety and reliability.

Key Features

• Triple modular redundant (TMR) architecture for high system availability and fault tolerance.
• T2V Certified IEC 61508 SIL 3, meeting the highest industrial safety standards.
• EN 50128 TUV Rheinland certified, ensuring compliance for safety-critical applications.
• Dedicated hardware and software test regimes validate operational integrity continuously.
• Automatic fault handling prevents nuisance alarms while maintaining safe system operation.
• Hot-swappable design allows replacement without shutting down the system.
• Front panel LED indicators provide real-time module status monitoring.
