2MLT-DMMA
This module integrates seamlessly with Honeywell’s 2MLR series, including the Honeywell 2MLR-CPUHT, acting as a dedicated data buffer that reduces processing load on the CPU while ensuring no critical measurements are lost. What distinguishes the Honeywell 2MLT-DMMA is its combination of high-capacity storage with thermal-hardened electronics—making it the only industrial data module capable of writing 10,000+ data points per second to non-volatile memory in 80°C environments. For system integrators, this translates to simplified data architectures, reliable compliance reporting, and enhanced troubleshooting capabilities in heat-intensive industries.
2MLT-DMMA
Main features and advantages:
The Honeywell 2MLT-DMMAdelivers exceptional data handling performance under thermal stress, featuring a dual-core data processor optimized for high-temperature operation. It can simultaneously acquire data from up to 32 analog and 64 digital channels, process it for anomalies, and store it locally—all without latency exceeding 50 milliseconds, even at maximum rated temperature. Its 128 GB industrial-grade solid-state drive (SSD) is rated for 3,000+ thermal cycles, retaining data for 10 years without power—critical for compliance in industries with strict record-keeping requirements.
Hardware design prioritizes data security in harsh conditions: military-grade encryption chips protect sensitive information, while a conformal coating resists corrosion from industrial contaminants like metal dust and chemical vapors. The module uses redundant storage pathways to prevent data loss during thermal spikes, with built-in error correction that automatically repairs corrupted packets. Compatibility is extensive: it natively connects to the Honeywell 2MLR-CPUHT via high-temperature module bus, supports Modbus TCP/IP for cold-zone communication, and integrates with Honeywell’s Experion PKS for centralized data visualization.

2MLT-DMMA
Application areas:
In industrial environments where critical process data must be captured, stored, and analyzed despite extreme conditions, the Honeywell 2MLT-DMMAemerges as a vital data management module. It excels in aluminum smelting facilities, where it collects real-time temperature and current data from electrolysis cells—operating reliably alongside the Honeywell 2MLR-CPUHT in control rooms that regularly reach 75°C. In thermal power plants, the Honeywell 2MLT-DMMA archives combustion efficiency metrics from boiler sensors, ensuring regulatory compliance even as nearby steam pipes raise ambient temperatures beyond the tolerance of standard data loggers.
Waste-to-energy facilities rely on the Honeywell 2MLT-DMMA to synchronize and timestamp data from emission monitors and fuel feed systems, providing an unbroken audit trail for environmental agencies. Across these heat-intensive settings, the module addresses unique challenges: maintaining data integrity in extreme temperatures, compressing large datasets for efficient storage, and securely transmitting information to cold-zone servers—all while operating without active cooling. Its ability to integrate with high-temperature CPUs like the Honeywell 2MLR-CPUHT makes it indispensable for engineers building comprehensive control and monitoring systems in harsh industrial zones.

Installation and maintenance:
Before installing the Honeywell 2MLT-DMMA, ensure it is mounted within 3 meters of the Honeywell 2MLR-CPUHT to minimize signal latency over the module bus—longer distances require shielded, high-temperature cabling rated for 105°C. Verify that the mounting surface can dissipate 12W of heat; pairing with a metal-backed DIN rail improves thermal conductivity. For installations near direct heat sources (e.g., furnace exhausts), use reflective heat shields to prevent radiant temperature spikes exceeding 85°C, which can temporarily reduce data write speeds.
For maintenance, perform quarterly data integrity checks using Honeywell’s DataValidator HT tool, which verifies file hashes to detect corruption from thermal stress. Inspect Ethernet connections semi-annually, ensuring torque remains at 0.5 N·m—thermal cycling can loosen connectors over time. Archive critical data to cold-zone storage annually, using the module’s built-in compression feature to reduce file sizes by up to 70%. The Honeywell 2MLT-DMMA includes self-monitoring diagnostics that alert via the Honeywell 2MLR-CPUHT if storage capacity drops below 15% or if error rates exceed thresholds—address these alerts promptly to prevent data loss.
