Product Description

The ICS Triplex T8110B is a high-integrity, triple modular redundant (TMR) processor designed for safety-critical control systems. Serving as the central processing unit in Trusted™ safety systems, it ensures uninterrupted operation in applications where system failure could result in hazardous conditions. Its architecture and diagnostics are engineered for maximum reliability and compliance with SIL 3 (IEC 61508) requirements.

Key Features and Capabilities

Triple Modular Redundancy (TMR) Architecture
The processor features three independent processing channels operating in parallel, with a 2-out-of-3 voting mechanism to detect and isolate faults. This guarantees continued system operation even if a single module fails.

High-Speed Processing
The T8110B provides tightly synchronized execution across all channels and rapid logic scanning, ensuring deterministic response times critical for Emergency Shutdown (ESD), Burner Management Systems (BMS), and Fire & Gas (F&G) applications.

Comprehensive Self-Diagnostics
Continuous internal testing identifies and isolates errors while maintaining system availability. Faults trigger alarms, and the system continues in degraded mode until full redundancy is restored. Modules are fully hot-swappable to minimize downtime.

Connectivity
Supports peer-to-peer communication with other Trusted™ controllers and integrates seamlessly via T8151B interface modules for Modbus or Ethernet/IP connections to Distributed Control Systems (DCS) and HMIs.

Technical Specifications

Typical Applications

Emergency Shutdown (ESD)
Ensures rapid and reliable shutdown of oil, gas, and chemical processes in hazardous conditions.

Fire and Gas (F&G) Systems
Monitors sensor networks and activates suppression systems when thresholds are exceeded.

Turbomachinery Overspeed Protection
Provides critical control for large turbines, safeguarding against mechanical or process failure.

Burner Management Systems (BMS)
Controls safe startup, operation, and shutdown of industrial boilers and furnaces.

FAQ

Q: Can the module operate if one processor slice fails?
A: Yes, the 2oo3 voting logic allows the system to run safely in degraded mode while maintaining core functionality.

Q: Is the module compatible with existing T8100 chassis systems?
A: Yes, the T8110B is fully compatible and hot-swappable within T8100 system backplanes.

Q: What kind of memory does it use for program storage?
A: It uses a combination of DRAM, EPROM, FLASH, and NVRAM for program and retained variable storage.
