Allen Bradley T8403 ICS Triplex Module

Allen-Bradley is Rockwell Automation’s flagship brand for industrial control and automation—covering PLCs/PACs (ControlLogix 1756, CompactLogix 5069/1769, MicroLogix), legacy SLC-500 (1747) / PLC-5 spares, I/O modules (1746/1756), PanelView HMI, PowerFlex drives, industrial EtherNet/IP networking, and safety/IS options for harsh environments. Widely used in oil & gas, petrochemical, power, marine and manufacturing, Allen-Bradley hardware delivers high uptime, long lifecycle support, and smooth migration paths from legacy platforms to modern architectures.

ICS Triplex Trusted™ is Rockwell Automation’s high-integrity TMR (Triple Modular Redundant) safety PLC platform for SIL2/SIL3 applications across oil & gas, petrochemical, power generation, and marine. Trusted systems are engineered for high availability, fault tolerance, and online maintainability—with rugged, conformally coated modules, extensive self-diagnostics, and hot-swappable I/O that reduce unplanned downtime. The ecosystem includes processors, I/O carriers, power supplies, communication interfaces, chassis, and thermal management assemblies such as rack-mounted fan trays (e.g., T8270) that maintain optimal airflow and extend system life in harsh environments. Trusted integrates cleanly with ESD, F&G, turbomachinery, and HIPPS, supporting long lifecycle projects where reliability and backwards compatibility matter.
