The ICS Triplex T8110B is a fundamental processor module within the renowned Trusted® Fault Tolerant Controllery system from ICS Triplex (now part of Rockwell Automation). This module is engineered to deliver the highest levels of reliability and availability for critical process safety applications, serving as a core component in Safety Instrumented Systems (SIS).
On an offshore drilling platform, a sudden pressure surge in a gas pipeline demands an instantaneous and fail-safe response. The ICS Triplex T8110B, housed within the Trusted system chassis, receives the signal from triple-redundant sensors. Its three independent processors execute identical logic in parallel. Even if one channel were to fail, the robust 2-out-of-3 (2oo3) voting mechanism of the T8110B ensures the correct shutdown command is sent without hesitation, preventing a catastrophic event. It addresses the ultimate pain point: guaranteeing functional safety and preventing dangerous failures in the most demanding environments.

The ICS Triplex T8110B is the embodiment of fault-tolerant engineering, with its value derived from several core innovations:
· •Innovation Point 1: True Hardware-based TMR Architecture: Unlike systems that use software for redundancy, the T8110B implements redundancy at the hardware level. Three separate processor channels operate simultaneously. This hardware-centric approach eliminates common cause failures associated with software and provides a deterministic, ultra-fast response to process demands.
· •Innovation Point 2: Robust Synchronization and Voting: The module employs a sophisticated, high-speed synchronization bus to keep all three processor channels operating in perfect lockstep. The continuous 2oo3 voting on both inputs and outputs happens at the hardware level, ensuring that a single fault in any part of the system—be it a processor, power supply, or input card—is masked without affecting the system's operation or safety integrity.
· •Innovation Point 3: Comprehensive Fault Management and Diagnostics: The T8110B features extensive online diagnostics that continuously monitor the health of each processor channel and its memory. Faults are detected, reported, and isolated immediately. This allows for predictive maintenance and enables the module to be replaced online without requiring a process shutdown, maximizing plant availability.
A major liquefied natural gas (LNG) train was experiencing unplanned shutdowns due to spurious trips in its legacy safety system, each costing millions in lost production. After migrating to a Trusted system centered on the ICS Triplex T8110B processors, the facility achieved unprecedented stability. The system's ability to correctly diagnose and isolate transient faults, rather than initiating a full shutdown, eliminated the nuisance trips. Over five years of continuous operation, the plant reported 99.999% availability of its safety system, directly attributable to the reliability of the T8110B, resulting in massive operational savings and enhanced asset protection.
The ICS Triplex T8110B functions as part of a integrated, fault-tolerant system. Essential related modules include:
· •ICS Triplex T8461: A triple-redundant analog input module that provides critical process data (e.g., 4-20mA signals) to the T8110B processors.
· •ICS Triplex T8431: A triple-redundant digital output module used to execute safety commands (e.g., closing shutdown valves) based on the logic solved by the T8110B.
· •ICS Triplex T8151B: A powerful communications processor that acts as a gateway, connecting the Trusted system with external assets like DCS or HMIs.
· •ICS Triplex A3700: The robust power supply unit that provides conditioned, redundant power to the entire chassis, including the critical T8110B modules.
· •ICS Triplex T8403: A digital input module for reading discrete signals from the field, such as emergency stop buttons or switch positions.
The ICS Triplex T8110B is designed for high availability and serviceability. Installation and replacement are performed by trained personnel and are facilitated by the module's hot-swap capability, which allows for maintenance without taking the safety system offline. The module slides into a dedicated slot in the Trusted chassis, with guide rails ensuring perfect connector alignment.Maintenance is largely predictive, driven by the module's extensive diagnostic reporting. The system provides clear alerts for any detected faults, allowing maintenance to be planned during scheduled turnarounds. This proactive approach maximizes system uptime. We provide end-to-end support, from initial system configuration and SIL verification to 24/7 technical support and lifecycle management services for your T8110B and the entire Trusted system.
