Description

Designed to provide reliable system power for critical process automation, the Honeywell 2MLR-AC23 is a high-performance redundant power supply module. This module is engineered specifically for the MasterLogic programmable logic controller (PLC) platform, ensuring high availability and continuous operation for redundant CPU systems, including the 2MLRCPUH/T and 2MLRCPUH/F controller configurations.

The 2MLR-AC23 converts incoming AC utility power to the regulated DC voltage required by the system backplane and connected I/O modules. Its redundant architecture allows for dual-module installation on redundant backplanes, safeguarding against power failures and minimizing unplanned downtime in demanding industrial environments.

Features

  • Engineered for high-availability MasterLogic redundant CPU systems.
  • Supplies highly regulated 5V DC power directly to the system backplane.
  • Supports redundant, parallel power configurations to prevent single-point failures.
  • Built-in overcurrent and overvoltage protective circuitry.
  • Rugged construction designed for reliable performance in harsh industrial settings.

Applications

  • Power Generation and Distribution Systems
  • Oil and Gas Refining and Processing
  • Water and Wastewater Treatment Facilities
  • Chemical and Petrochemical Processing
  • Heavy Industrial Manufacturing and Automation
