ICS Triplex T8111 Trusted TMR Processor Module 100 MHz

Description

The ICS Triplex T8111 is a high-availability main processor module designed for the Trusted Triple Modular Redundancy (TMR) system. It executes complex safety logic and manages system-wide coordination using a hardware-implemented fault-tolerant architecture to ensure continuous process operation in SIL3 environments.

Specifications

• Manufacturer: Rockwell Automation (ICS Triplex).

• Country of Origin: United Kingdom / USA.

• Model Number: T8111.

• Clock Speed: 100 MHz internal frequency.

• Memory Resources: 16 MB DRAM and 2 MB Flash memory.

• Input Voltage: 24 VDC nominal (Range 20–32 VDC).

• Power Consumption: 25 Watts maximum.

• Physical Weight: Approximately 1.25 kg (2.75 lbs).

• Dimensions: 10.5" x 1.2" x 7.8" (266 mm x 31 mm x 198 mm).

Features

• Triple Modular Redundancy: Utilizes three independent processing paths with hardware-based 2-out-of-3 (2oo3) voting for absolute data integrity.

• Hardware Implemented Fault Tolerance: Features a specialized HIFT architecture that detects and isolates faults within a single scan cycle.

• Deterministic Scan Execution: Guarantees consistent logic processing times regardless of communication load, essential for high-speed shutdown systems.

• Online Hot-Swap: Supports module replacement during live operation without necessitating a system shutdown or logic interruption.

• Robust Self-Diagnostics: Conducts comprehensive internal health checks on memory, logic gates, and bus interfaces every millisecond.

• Error Correction Code Memory: Employs ECC RAM to automatically detect and correct single-bit errors, preventing unexpected system trips.
