product description：

ICS TRIPLEX c Trusted TMR Expander Interface.The ICS Triplex T8311 Trusted TMR Expander Interface is a component used in industrial control systems. It provides a trusted triple modular redundancy (TMR) interface for connecting to other devices in the system. Related products: T8311C is module with coating.ICS TRIPLEX T8110B ROCKWELL Trusted TMR Module.

The TrustedTM TMR Expander Interface module resides in the TrustedTM 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 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.
