ICS T8311 Trusted TMR Expander Interface

ICS T8311
Trusted TMR Expander Interface
Product Overview
The Trusted® TMR Expander Interface Module resides in the Trusted Controller Chassis and
provides the ‘master’ interface between the Inter-Module Bus (IMB) in the Controller Chassis and
the Expander Bus. The Expander Bus allows multiple chassis systems to be implemented using
Unshielded Twisted Pair (UTP) cable connections whilst maintaining the fault tolerant, high
bandwidth IMB capabilities.
The Module provides fault containment for the Expander Bus, the Module itself and the IMB in the
Controller Chassis, ensuring that the effects of these potential faults are localised and system
availability maximised. The Module is fault tolerant with HIFT TMR architecture. Comprehensive
diagnostics, monitoring and testing provide rapid fault identification. Hot-standby and module
spare slot configurations are supported, allowing automatic and manual repair strategies.
Features:
• Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation.
• Hardware Implemented Fault Tolerant (HIFT) architecture.
• Dedicated hardware and software test regimes which provide very fast fault recognition and
response times.
• Automatic fault handling without nuisance alarming.
• Hot replacement.
• Front Panel indicators that show module health and status.
• TϋV Certified IEC 61508 SIL 3.
