ICS Triplex T8680 Trusted TMR Module

The ICS Triplex T8680 module delivers high-integrity processing for safety-critical industrial control systems. As a core component of the Trusted Triple Modular Redundant architecture, this unit ensures continuous operation even during hardware faults. Engineers select this module for emergency shutdown and fire and gas applications worldwide.

Key Technical Specifications

The T8680 operates with a triple modular redundant design, providing fault tolerance without compromising performance. Each module weighs approximately 1.2 kg and measures 160 mm by 100 mm by 40 mm. The unit draws power from a 24 VDC supply and dissipates roughly 15 watts during normal operation.

Interface and Communication

The T8680 connects directly to the Trusted backplane, enabling seamless data exchange across redundant channels. Consequently, each processing lane operates independently while voting logic resolves discrepancies in real time. The module supports hot-swap replacement, which minimizes downtime during maintenance activities. Furthermore, dual communication paths ensure reliable data transfer between the processor and I/O modules.

Component Count and Energy Storage

Each T8680 module contains three independent processing lanes on a single assembly. Additionally, onboard energy storage supports brief ride-through during power interruptions. The module integrates watchdog timers and diagnostic circuitry for continuous self-monitoring. Therefore, operators gain confidence in system integrity across demanding industrial environments.

Applications and Reliability

Oil and gas facilities, chemical plants, and power generation stations deploy the T8680 for critical safety functions. The TMR architecture achieves SIL 3 certification, meeting rigorous international safety standards. Meanwhile, comprehensive diagnostics alert maintenance teams before failures escalate. As a result, plant operators reduce unplanned shutdowns and protect expensive assets.
