The Honeywell 2MLF-AV8A is a high-performance analog output module engineered to serve as a critical control interface within Honeywell’s Experion PKS and Building Management System (BMS) architectures. As a bridge between digital control systems and analog actuators, it converts computed control signals into continuous physical outputs (such as current or voltage) to regulate industrial equipment.
2MLF-AV8A
This module integrates seamlessly with Honeywell’s PlantScape and SymmetrE platforms, acting as an execution layer that ensures precise signal conversion with minimal latency. What distinguishes the Honeywell 2MLF-AV8A is its ability to independently configure each output channel for different signal types—eliminating the need for external signal converters in mixed-actuator systems. For engineers, this translates to flexible system design, reduced component count, and simplified troubleshooting through centralized diagnostics.
2MLF-AV8A
Main features and advantages:
The Honeywell2MLF-AV8A delivers exceptional output accuracy, with 16-bit resolution that maintains control within 0.15% of setpoint—critical for applications like pharmaceutical blending, where minor deviations can compromise product quality. Its hardware design features a rugged metal housing with integrated EMI/RFI shielding, protecting sensitive output circuits from electrical noise in environments with high-power machinery.
A key strength is its output flexibility: each of the 8 channels can be independently configured for 4-20mA, 0-10V, or 0-5V signals, allowing seamless integration with both Honeywell and third-party actuators. This versatility reduces inventory costs for system builders managing diverse projects. Long-term reliability is enhanced by built-in overcurrent protection (up to 50mA per channel) and short-circuit immunity, preventing damage from wiring errors or actuator faults. The Honeywell 2MLF-AV8A operates efficiently in temperatures up to 60°C, ensuring stable performance in enclosed control cabinets without active cooling.

Application areas:
In industrial process control environments where precise actuation of valves, dampers, and variable speed drives determines operational efficiency, the Honeywell 2MLF-AV8A stands as a critical component. It excels in water treatment plants, where regulating chemical dosing pumps within ±0.5% accuracy prevents over-treatment and reduces operational costs. In automotive paint shops, where consistent airflow control is vital to maintaining coating quality, the Honeywell 2MLF-AV8A coordinates with actuators to adjust ventilation rates in real time, responding to changes in production volume.
Food and beverage processing lines rely on the Honeywell 2MLF-AV8A to control mixing speeds and heating elements, ensuring product consistency across batches. Across these industrial automation settings, the module addresses key challenges: translating digital control signals into precise analog outputs, maintaining stability during voltage fluctuations, and integrating with diverse actuation systems—all while providing diagnostic feedback to prevent unplanned downtime. Its robust design allows reliable operation in both clean manufacturing areas and harsh industrial zones, making it a versatile choice for system integrators.

Installation and maintenance:
Before installing the Honeywell 2MLF-AV8A, verify that the mounting rail is properly grounded and secured to minimize vibration, which can cause intermittent connections in high-current output channels. Ensure a minimum clearance of 30 mm on all sides to facilitate heat dissipation—critical when operating multiple channels at maximum current. Check that connected actuators are compatible with the module’s output ranges; exceeding voltage or current limits can damage both the module and connected equipment. Use twisted-pair wiring for all output connections, with shielding connected to the control cabinet ground, to reduce electromagnetic interference that can cause output instability.
For maintenance, perform quarterly checks using Honeywell’s HC900 Configuration Studio to verify output linearity and calibration offsets. Inspect terminal blocks bi-annually to ensure torque remains at 0.5 N·m—loose connections are a primary cause of output drift. Clean the module exterior with a dry cloth during scheduled shutdowns; avoid using cleaning solvents that could degrade the housing. The Honeywell 2MLF-AV8A features self-diagnostic capabilities that flag faults via LED indicators, but annual functional testing with a calibrated signal generator ensures long-term accuracy. During firmware updates, ensure the module is disconnected from actuators to prevent unintended outputs during reboots.
