Honeywell 2MLR-CPUH/T-CC Redundant CPU Module – Experion PKS Process Knowledge System
When a DCS CPU module fails mid-operation, the consequences extend far beyond a simple system restart. In high-stakes process industries — oil refineries, chemical plants, power generation facilities — an unplanned controller outage can trigger emergency shutdowns, product loss, safety incidents, and regulatory violations. Every second of downtime translates directly into measurable financial and operational damage. The Honeywell 2MLR-CPUH/T-CC is engineered precisely to eliminate this risk, delivering hardware-level redundancy that keeps your process running even when one CPU encounters a fault.
The 2MLR-CPUH/T-CC is a high-performance redundant CPU module within Honeywell’s Experion PKS (Process Knowledge System) platform — one of the world’s most widely deployed DCS architectures in continuous process industries. The “CPUH” designation denotes the High-Performance CPU variant, while “/T-CC” indicates Triple/Continuous Controller configuration with bumpless switchover capability. This module occupies a critical tier in the Experion PKS control hierarchy, serving as the primary execution engine for regulatory, advanced, and safety-integrated control strategies across global industrial installations.
