Product Description

ICS Triplex T8311 | Trusted TMR Expander Interface Module

HIFT TMR Master Interface Between Controller IMB & Expander Bus - Fault-Tolerant Distributed I/O Expansion for SIL 3 Safety-Critical Systems

1. Product Overview

The ICS Triplex T8311 is a Hardware-Implemented Fault-Tolerant (HIFT) Triple Modular Redundancy (TMR) expander interface module, serving as the master interface between the Inter-Module Bus (IMB) in the Trusted controller chassis and the Expander Bus in Rockwell Automation's Trusted safety instrumented system (SIS). It occupies the leftmost processor slot of the controller chassis, enabling distributed I/O expansion via Unshielded Twisted Pair (UTP) cable connections while maintaining the fault-tolerant integrity of the IMB (250 Mbps data transfer rate). The module utilizes HIFT TMR architecture (3-2-0 operation) with comprehensive diagnostic capabilities, ensuring rapid fault identification and containment to prevent fault propagation across chassis. It connects to expander chassis via TC-301 hot-link cable and supports hot-standby/spare module configurations for automatic/manual repair strategies. With dual redundant 24 V DC power from the controller chassis backplane, -40°C to +70°C operating temperature range, and SIL 3 compliance (IEC 61508), it delivers reliable chassis-to-chassis communication and I/O expansion for high-availability safety applications in oil & gas, petrochemical, nuclear power, and chemical industries, maximizing system scalability without compromising fault tolerance.

4. Installation & Maintenance

Installation: Mount in leftmost processor slot of controller chassis; connect TC-301 cable to expander chassis (T8310 module side); wire dual redundant 24 V DC power from backplane; power on and verify LED status (Healthy: Green; Active: Green; TxRx: Amber for data transfer).

Maintenance: Weekly: Inspect LED indicators for fault detection; Monthly: Test communication link (250 Mbps data transfer); Annual: Review fault logs, update firmware, and simulate single-channel failure to test TMR voting logic.

Safety Notes: Use only TC-301 cables for controller-expander connection; validate TMR fault containment after configuration changes; maintain hot-standby module for rapid replacement; perform maintenance during non-critical process phases.
