Rockwell Automation ICS Triplex Trusted TMR Processor T8110B

Hardware Specifications

TMR Safety Processor Architecture

The ICS Triplex T8110B operates within the Trusted TMR platform and manages processor-level execution, communication processing, and sequence of events handling. The module uses triple modular redundancy (TMR) 2oo3 architecture principles to execute control functions with fault monitoring capability.

Furthermore, the processor module supports fail-safe state execution by maintaining synchronized processor operation across the redundant architecture. The hardware design includes dedicated memory resources for application execution, event storage, and system data retention.

The T8110B supports IRIG-B002 and IRIG-B122 time synchronization inputs for coordinated event recording. Additionally, the module provides RS422/485 serial communication interfaces for external system connections and diagnostic data exchange.

Field Installation Guidelines

Install the T8110B module into the designated T8100 chassis slot according to the Trusted TMR system hardware configuration requirements.

Before installation, verify that the chassis power supply provides a 20 VDC to 32 VDC input range and that the system power budget supports the module load. Connect RS422/485 communication wiring using appropriate shielded cables and maintain separation from high-current power conductors to reduce electrical interference.

Ground cable shields according to the system grounding design and avoid unnecessary cable loops near communication terminals. Confirm that the IRIG-B time synchronization wiring uses correct signal polarity and termination practices before system commissioning.

Perform module diagnostics and verify processor synchronization status after installation. Confirm communication links, event recording functions, and redundant processor operation before placing the system into service.
