Honeywell 2MLF-DV8A MasterLogic-200 Analog Output Module

The Honeywell 2MLF-DV8A (V1.0) is an 8-channel digital-to-analog converter module engineered for the MasterLogic-200 PLC platform. It provides high-precision analog voltage outputs to drive control valves, actuators, and speed drives across multiple industrial loop control applications.

Voltage Output Capabilities and Channel Speed

The module supports four selectable DC voltage output ranges: 0 to 10 VDC, -10 to 10 VDC, 0 to 5 VDC, and 1 to 5 VDC, requiring a minimum load resistance of 1 kohm. It delivers output accuracy within +/-0.1% with a resolution of 0.1%, an analog response time under 1 ms, and a conversion speed under 100 ms across all eight channels.

Power Requirements and Electrical Isolation

System backplane current consumption is approximately 340 mA at 5 VDC, with a nominal operating voltage requirement of 24 VDC. For field isolation, the module maintains an isolation voltage rating of AC 560 V rms (3 cycles, up to 2000 m altitude) and an isolation resistance of at least 10 Mohm measured by megger.

Physical and Environmental Specifications

The module features a compact footprint measuring 100 mm x 120 mm x 50 mm and weighing 0.5 kg, with support for DIN rail or panel mounting. Standard operating temperature ranges from -20 deg C to +70 deg C (with select variants rated for 0 deg C to +55 deg C), accommodating ambient humidity levels from 5% to 95% RH (non-condensing).
