ICS Triplex T8110B Trusted TMR Processor Module

ICS Triplex T8110B Trusted TMR Processor Module

Configured for triple modular redundant safety control execution in the Trusted TMR system, the ICS Triplex T8110B (T8110B Processor Module) provides direct processor-level execution, redundant power handling, and deterministic communication processing through the Trusted controller architecture.

Hardware Specifications

Triple Modular Redundancy and Safety Execution

The ICS Triplex T8110B operates with a TMR processing architecture using three synchronized RISC processor channels. Each processor executes identical application logic, with internal comparison mechanisms used for fault detection and continued safety execution. The module supports IEC 61508 SIL 3 certified Trusted OS operation and maintains fail-safe state execution through hardware-level diagnostic monitoring.

The processor module includes redundant 20-32 VDC power inputs with reverse polarity protection, overvoltage clamping, and current limiting functions. The redundant power structure supports continued operation during individual power input faults within the defined system configuration.

Frequently Asked Questions

Q: What communication interfaces are available on the T8110B processor module? A: The module provides two RS422/485 ports supporting 2-wire and 4-wire configurations, one RS485 2-wire connection, and IRIG-B 002/122 time synchronization inputs.

Q: Does the T8110B support online module replacement? A: The T8110B supports hot-swappable replacement within the Trusted TMR chassis configuration. Replacement procedures must follow system installation and maintenance requirements.

Q: How does the TMR architecture handle processor faults? A: The module uses three synchronized processor channels with internal diagnostic comparison to identify channel deviations and maintain safety control execution.

Field Installation Guidelines

Install the T8110B processor module in a compatible Trusted T8100 chassis with correct mechanical alignment and backplane engagement. Verify that redundant DC power connections follow the system wiring specification before energizing the module.

Use shielded communication cables for RS422/485 interfaces where required by the installation environment. Connect cable shields according to site grounding practices to reduce electromagnetic interference. Separate communication wiring from high-current power conductors to minimize signal coupling.

Confirm chassis grounding, power polarity, and connector seating before operation. Verify front panel status indicators after startup to confirm processor, communication, and synchronization conditions.
