Description

Brief Product Description

The Honeywell MLI-DR28UA is a versatile MasterLogic ML50U base module that integrates digital inputs, relay outputs, and configurable analog I/O into a single high-performance unit. Operating on a universal 100–240V AC power supply, it provides a compact and reliable foundation for complex industrial automation and machine control.

​Product Description

The Honeywell MLI-DR28UA functions as the primary architectural foundation for the MasterLogic ML50U controller series. This integrated base module streamlines industrial automation by consolidating discrete and variable signal processing into one hardware footprint. Because it supports a broad power input range from 100V to 240V AC, the unit operates reliably across international power grids, making it a global solution for distributed control systems (DCS) and standalone machinery.

Multimodal I/O Integration

Engineers can leverage the high-density signal capacity of the MLI-DR28UA to manage diverse field devices simultaneously. The module features 16 dedicated digital inputs and 12 robust relay outputs, which handle high-current switching for solenoids, motor starters, and indicators. Furthermore, the unit incorporates 8 analog channels that users can configure for either input (AI) or output (AO) tasks. These channels support standard industrial voltage and current loops, allowing for precise interaction with pressure sensors, flow meters, and variable frequency drives.

Network Connectivity and Communication

The MLI-DR28UA actively facilitates high-speed data exchange through its dual-network support, featuring both FENET and 2SNET communication interfaces. This connectivity ensures that the base module can synchronize effortlessly with peer controllers and HMI stations within a larger industrial network. By providing these native communication ports, Honeywell reduces the need for additional gateway hardware, thereby simplifying the overall system topology and lowering the total cost of ownership.

Industrial Design and Deployment

The mechanical construction of the MLI-DR28UA emphasizes space efficiency and long-term durability. By housing digital, relay, and analog functions in one compact chassis, the module significantly reduces required cabinet space and simplifies complex wiring looms. Its ruggedized exterior withstands the mechanical vibration and electrical noise inherent in manufacturing environments. Consequently, the MLI-DR28UA remains a preferred choice for facilities requiring a highly reliable, all-in-one programmable logic solution that is easy to maintain and scale.
