ICS Triplex T8312-4C Trusted TMR Expander Interface Module

Description

The ICS Triplex T8312-4C is a conformal-coated Trusted TMR Expander Interface module designed for harsh industrial environments. It provides the high-speed communication link necessary to extend the triplicated inter-module bus from the controller chassis to up to four expansion chassis.

Specifications

• Chassis Capacity: Connects 1 controller chassis to up to 4 expander chassis.

• Safety Rating: IEC 61508 SIL 3 certified.

• Coating: Conformal coated for protection against harsh/corrosive environments (Class G3).

• Architecture: Triple Modular Redundant (TMR) 2oo3 voting logic.

• Operating Voltage: 24 Vdc nominal (20 to 32 Vdc range).

• Power Consumption: 15 W typical; 22 W maximum.

• Interface Ports: Three high-speed triplicated expander bus ports.

• Isolation: 50 V sustained channel-to-chassis isolation.

• Operating Temperature: -5°C to +60°C (standard range).

Features

• Environmental Protection: Features high-grade conformal coating to prevent board degradation from humidity and chemical contaminants.

• Fault-Tolerant Extension: Maintains full triple redundancy across the expanded system, ensuring no single cable or port failure interrupts operations.

• Hot-Swap Capability: Supports module replacement during live operation without tripping the safety system or stopping logic execution.

• Hardware-Based Voting: Implemented via hardware to ensure high-speed data integrity and low-latency synchronization between chassis.

• Automatic Recognition: Seamlessly integrates with Trusted system software for automated module addressing and status monitoring.

• Comprehensive Diagnostics: Includes front-panel LED indicators for real-time status of bus health, power, and internal module faults.
