Description

Brief Product Description

The Honeywell MLI-DR10E is a versatile MasterLogic PLC base module featuring 6 discrete DC24V inputs and 4 high-reliability relay outputs. This compact controller integrates a universal AC power supply with high-speed logic processing to manage essential industrial automation tasks.

​Product Description

High-Speed Logic Processing and Memory

The Honeywell MLI-DR10E serves as a core processing unit within the MasterLogic PLC family, delivering rapid execution speeds of 240ns per instruction step. This processing power allows the module to manage up to 128 independent programs and 4k steps of logic within its 50kB internal memory. Because the system supports repetitive, cyclic, and direct instruction modes, engineers can implement complex control sequences with high temporal precision. This functionality makes the MLI-DR10E an ideal choice for localized machine control and auxiliary DCS tasks where responsiveness is a critical requirement.

Integrated I/O and Universal Power Architecture

This base module simplifies installation by combining a wide-range AC power supply (100–240V) with a balanced 10-point I/O density. The hardware configuration includes 6 channels of 24VDC digital inputs and 4 robust relay outputs, providing a direct interface for field sensors and actuators. To ensure signal purity and protect internal electronics, the module utilizes advanced photo-coupler isolation. Furthermore, the input circuitry maintains stable performance across a broad voltage range of 20.4V to 28.8V, effectively filtering out common industrial power ripples and electrical noise.

Industrial Reliability and Electrical Safety

Honeywell designed the MLI-DR10E to thrive in rigorous industrial environments by prioritizing electrical insulation and physical durability. The module features an insulation pressure rating of AC560Vrms, ensuring the unit can withstand significant transient voltage spikes without failure. Additionally, the precise ON/OFF voltage thresholds and standardized input resistance ensure consistent detection of field device states. Despite its lightweight 0.4kg footprint, the module provides the mechanical and electrical resilience necessary for long-term deployment in critical process control infrastructures.
