2MLF-AD16A | Honeywell | MasterLogic-200 Analog Input Modules
The 2MLF-AD16A is a Honeywell MasterLogic-200 analog input module with 16 channels per module. It converts analog signals at 500 μs per channel. Accuracy is ±0.2% or less at 25±5°C, and ±0.3% or less from 0 to 55°C. A photo-coupler isolates the input terminal from PLC power. There is no isolation between channels. The module uses a 32-point terminal. It draws DC 5V, 330mA internal current. This module fits machine builders and process plants that need dense, fast analog input in a MasterLogic-200 rack.

Oiltech Controls’s Insight
- The 2MLF-AD16A packs 16 analog inputs in one slot. This saves rack space on dense I/O counts.
- 500 μs/channel conversion suits fast loop scanning and trend capture.
- Photo-coupler isolation protects PLC power from field transients.
- Channels share no isolation. Keep single-ended field wiring clean to avoid cross-talk.
- The 32-point terminal allows direct field wiring without extra terminal blocks.
- Accuracy stays within ±0.3% across the full 0~55°C range.
Where It Fits
- Honeywell MasterLogic-200 PLC racks that need analog input expansion.
- Machine builders that monitor pressure, flow, temperature, or level signals.
- Process plants that need fast scan of many analog points.
- Panel shops wiring 4~20 mA or voltage loops into a compact terminal.
- Retrofit projects that keep existing MasterLogic-200 hardware in service.
Supply and Warranty Terms
- 12-month warranty on the module.
- Orders ship within 24 to 28 hours.
- Shipping by FedEx, UPS, and DHL.
- Each unit is checked before packing.
FAQ
Q: How fast can I expect dispatch for the 2MLF-AD16A?
A: We dispatch within 24 to 28 hours after order confirmation. We ship by FedEx, UPS, or DHL. You get a tracking number at pickup.
Q: Do the 16 channels need separate isolation modules?
A: No, they do not. The module isolates input terminal from PLC power with a photo-coupler. Channels are not isolated from each other. In practice, keep field commons at one point to limit cross-talk. If a field loop sits near drives, add a signal isolator per channel.
Q: What should I check before I buy this module for my rack?
A: Check three things. First, your rack is MasterLogic-200. Second, your spare slot can supply DC 5V, 330mA. Third, your wiring lands on a 32-point terminal. Confirm the fixed or variable I/O address mode in your project file. Fixed mode uses 64 points. Variable mode uses 16 points.
Q: Will accuracy drift in a hot panel?
A: Accuracy is ±0.2% or less at 25±5°C. It shifts to ±0.3% or less from 0 to 55°C. Keep cabinet temperature inside that band. Add forced air if the panel sits in a hot room. This keeps drift predictable across the day.
Q: What field conditions should I avoid?
A: Avoid corrosive gas, dust, and condensation. Keep altitude below 2000 m. Keep contamination below 2. Maintain 5~95%RH without condensation. In dusty plants, mount the rack in a sealed enclosure with filtered air.
