The Honeywell 2MLF‑DV8A, also cataloged as the 2MLF‑DV8A analogue output module, provides analogue output scaling for MasterLogic systems. It delivers channel‑selectable output ranges and digital formatting with defined conversion speed and photo‑coupler isolation between field terminals and PLC power.

Core Performance Indicators
8 analogue output channels, selectable output ranges, signed/unsigned/precise/percentile digital formats, 1/16000 resolution, ±0.2% accuracy at 25 deg C, ±0.3% accuracy across operating range, 250 µs/channel conversion speed, ±15 V absolute maximum output, photo‑coupler isolation, 18‑point terminal, changeable 16‑point or fixed 64‑point I/O occupation
4-20 mA HART Loop Protocol & Channel Formatting
Output ranges for each channel can be selected through the applicable program or parameter settings. Digital values support multiple formats:
Unsigned: 0 to 16000
Signed: -8000 to 8000
Precise: 0 to 5000
Percentile: 0 to 10000
Maximum resolution is 1/16000 for respective output ranges, equivalent to 0.250 mV. Accuracy is ±0.2% at 25 deg C and ±0.3% across the operational temperature range. Absolute maximum output is ±15 V. Photo‑coupler isolation is applied between input terminals and PLC power; channels are not isolated from each other.
Frequently Asked Questions
Q: Can each channel use a different digital value format A: Yes. Formatting is selectable per channel through program or parameter settings.
Q: Is isolation provided between channels A: No. Isolation exists only between field terminals and PLC power; channels share a common reference.
Q: What is the maximum conversion speed per channel A: 250 µs per channel, as specified.
Field Installation Guidelines
Use shielded twisted‑pair wiring for analogue loops and apply grounding at a single point to minimize noise. Maintain separation between analogue wiring and high‑current conductors. Ensure correct seating of the 18‑point terminal block. Verify that configured output ranges match the receiving device requirements and that loop loads remain within the module’s specified limits.
