The Honeywell 2MLT-DMMA is a dummy module designed for the MasterLogic-200 series PLCs. It is used to occupy unused I/O slots in the PLC chassis, ensuring protection and maintaining proper airflow within the system.
While it has no functional input/output points, the 2MLT-DMMA helps keep the system dust-free and organized.

Key features include:

• Dustproof design for system protection

• Compact dimensions: Width 45 mm, Height 70 mm, Depth 80 mm

• Simple snap-in installation

Although the 2MLT-DMMA is discontinued by Honeywell, it may still be available through select third-party automation suppliers. It’s a practical solution for maintaining system integrity when expansion is not immediately needed.
