ICS Triplex T8122 Trusted Interface Module

Description

The ICS Triplex T8122 is a Trusted Module Interface designed to facilitate high-speed communication between the Trusted TMR Processor and the I/O subsystem. It acts as a critical gateway, ensuring that triplicated data is correctly distributed and synchronized across the system's internal backplane.

Specifications

• Safety Rating: IEC 61508 SIL 3 certified.

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

• Power Consumption: 15 W typical; 20 W maximum.

• Communication Ports: Dual 10/100 Mbps Ethernet ports for peer-to-peer and host communication.

• Bus Interface: Triplicated Inter-Module Bus (IMB) connection.

• Architecture: 2oo3 (Two-out-of-three) hardware voting logic.

• Isolation: 50V sustained (tested to 1000V ac).

• Operating Temperature: -5°C to +60°C (standard) or -40°C to +70°C (extended).

• Weight: Approximately 0.70 kg (1.54 lbs).

Features

• Triplicated Data Integrity: Implements TMR architecture on the interface level to eliminate communication failures as a single point of failure.

• High-Speed Connectivity: Features redundant Ethernet interfaces to support robust data exchange with DCS, SCADA, or other Trusted controllers.

• Hot-Swap Support: Allows for module replacement during active system operation without interrupting the safety functions or logic execution.

• Diagnostic Reporting: Provides continuous monitoring of bus health and port status, with real-time feedback to the system fault historian.

• Seamless Backplane Integration: Plugs directly into the Trusted Controller Chassis, automatically linking to the T8111 processors via the internal bus.

• Synchronized Execution: Ensures that I/O updates are tightly synchronized with the processor scan cycle for precise timing in safety-critical loops.
