ICS Triplex T8151B | Rockwell AADvance TMR Processor Module
High-performance TMR processor with enhanced memory & processing power for SIL 3 safety-critical ESD/F&G/BMS control systems
1. Product Overview
The ICS Triplex T8151B is an enhanced high-performance Triple Modular Redundancy (TMR) processor module for Rockwell AADvance safety instrumented systems (SIS), engineered for safety-critical industrial applications requiring ultra-high reliability, faster processing speeds, and expanded memory capacity (compared to the T9110). Built on a fault-tolerant TMR architecture with three identical PowerPC 750FX processing channels (800 MHz), it incorporates voting logic to ensure continuous operation even during single-channel failures, making it ideal for emergency shutdown (ESD), fire & gas (F&G), burner management (BMS), and distributed control (DCS) systems in oil & gas, petrochemical, nuclear power, and chemical industries. It features 1 GB ECC DRAM (4× larger than T9110), 128 MB Flash memory, dual 10/100/1000 Mbps Gigabit Ethernet ports, and dual RS-232/422 serial ports for seamless communication with AADvance I/O modules, HMI, and SCADA systems. With hot-swappable design, -25°C to +60°C operating temperature range, and compliance with IEC 61508 (SIL 3), IEC 61511, and IEEE 1686 standards, it delivers superior processing performance for complex control logic while maintaining the fault tolerance and safety integrity required for mission-critical industrial processes, minimizing downtime and ensuring personnel/equipment safety.
