Product Description

Integrated Networking and Advanced Data Logging

The Honeywell MLI-DR28U excels in modern industrial environments by combining control logic with robust data management. This controller features dual-port Ethernet connectivity, which significantly reduces wiring complexity and installation costs through daisy-chaining capabilities. Beyond standard communication, the module functions as an FTP server, allowing users to manage logged data, access diagnostic information, and even configure automated email alerts with attached log files. To support extensive historical record-keeping, the hardware includes an external SD memory slot compatible with cards up to 16GB. This storage capacity enables the precise capturing of general parameters, trigger-based events, and cyclic process data for long-term analysis.

High-Speed Logic and Arithmetic Processing

Engineered for precision, the MLI-DR28U utilizes a powerful processor capable of executing basic instructions at a speed of 160ns per step. This rapid processing is complemented by advanced floating-point arithmetic support, making the module ideal for applications involving complex mathematical scaling and PID control loops. The system remains highly adaptable by offering multiple execution modes, including constant scan, interrupt-driven, and repetitive cycle operations. These features ensure that the controller maintains consistent performance even as the complexity of the user program increases.

Reliable Hardware and System Scalability

The hardware architecture of the AB MLI-DR28U emphasizes electrical safety and system longevity. It incorporates 16 input points and 12 output points, all of which utilize photo-coupler insulation to prevent electrical noise from damaging the internal logic circuits. The module operates on a standard 24VDC power supply with a wide tolerance range of 20.4V to 28.8V, ensuring stability during voltage fluctuations. While the base unit is compact, it serves as a foundation for larger systems; through modular expansion, the architecture can support a maximum of 348 I/O points. This scalability allows the Honeywell MLI-DR28U to grow alongside your facility’s operational requirements.
