Honeywell 2MLT-DMMA Dummy Module – Slot Filler for MasterLogic-200 PLC Systems
The Honeywell 2MLT-DMMA Dummy Module is a non-functional slot filler designed for the Honeywell MasterLogic-200 PLC series. Though it does not support any input or output operations, this module plays a vital role in maintaining the structural integrity, cleanliness, and performance of your PLC system by occupying unused I/O slots.
Ideal for industrial environments, the 2MLT-DMMA helps protect internal components by preventing dust, debris, and foreign objects from entering empty slots. Additionally, it promotes proper airflow and heat dissipation within the PLC chassis, supporting overall system longevity and efficiency. Whether you’re planning future expansion or simply want to maintain a clean, organized setup, this Honeywell dummy module offers a practical and cost-effective solution.
The module features a compact design with dimensions of 45 mm (W) x 70 mm (H) x 80 mm (D), allowing it to snap easily into place without any special tools or configuration. It’s an ideal placeholder for systems where I/O expansion is anticipated but not yet implemented.
Although officially discontinued by Honeywell, the 2MLT-DMMA may still be available through select third-party automation suppliers and trusted distributors. Its use remains relevant for professionals seeking to maintain system integrity and prevent environmental contamination in Honeywell MasterLogic-200 setups.
