Honeywell 1MLR-CPUB | Experion PKS C-Series | PLC CPU Module

Product Overview

The Honeywell 1MLR-CPUB PLC CPU module is a core processing unit engineered for the Experion PKS C-Series control platform, including seamless operation with C300 controllers. It provides deterministic control execution, system coordination, and high-availability operation within distributed control architectures.

Built for continuous industrial operation, this CPU module supports large-scale I/O processing, stable control cycle execution, and redundant system designs that reduce unplanned downtime in mission-critical environments.

Functional Description

The 1MLR-CPUB functions as the primary logic processor within a Honeywell C-Series control system. It executes control strategies, manages real-time data exchange with distributed I/O over the system backplane, and supervises system diagnostics. When configured in a redundant pair, the CPUs operate in parallel, enabling automatic failover without disrupting process operations.
