Product Overview

• Part No: MLU VER.A01
• Brand: ALSTOM

• Category: MLU Main Logic Unit Processor Module

   
  MLU VER.A01 is a high-performance Eurocard plug-in main logic processing unit developed by ALSTOM. VER.A01 represents the official hardware revision version. As the core logic controller inside the control rack, it undertakes real-time logic operation, signal processing, system scheduling and data communication tasks. The module exchanges data with I/O boards, communication modules and upper monitoring systems via backplane bus, executes user control logic, fault monitoring and interlock protection algorithms. Equipped with on-board high-speed processor, front panel LED diagnostic indicators, Ethernet interface and built-in ESD & surge suppression circuits, it maintains stable continuous operation under strong electromagnetic interference. It is an important maintenance spare part for power generation automation and large-scale industrial control racks.
