2MLF-AV8A Analog Voltage Input Module (Industrial-Grade 8-Channel Acquisition)

Engineered for demanding industrial environments, the 2MLF-AV8A delivers precision analog voltage measurement across eight differential input channels. This MasterLogic-200 compatible module transforms continuous voltage signals from sensors, transmitters, and field devices into accurate digital data for real-time process control and monitoring applications.

Manufacturing facilities, power plants, and process industries rely on this module to capture critical operational parameters—temperature variations, pressure fluctuations, flow rates, and level measurements—with consistent accuracy. Its dual-range capability (0-10V and ±10V) accommodates diverse sensor types without external signal conditioning, reducing installation complexity and system costs.

Built to withstand harsh industrial conditions, the 2MLF-AV8A features channel-to-channel isolation, high input impedance, and factory calibration that ensures measurement integrity from day one. Whether expanding existing MasterLogic-200 systems or designing new installations, this module provides the reliable data acquisition foundation your operations demand.

Frequently Asked Questions

Can the 2MLF-AV8A interface with current loop transmitters?
This module is optimized for voltage inputs (0-10V, ±10V). For 4-20mA current loop sensors, you'll need a current input module or external current-to-voltage converter. Contact our team for current input module recommendations compatible with MasterLogic-200 systems.

What cable specifications are recommended for analog input wiring?
Use shielded twisted-pair cable with 18-22 AWG conductors. Keep cable runs under 100 meters (328 feet) to minimize noise pickup. Ground cable shields at one end only (typically at the module) to prevent ground loops.

Is individual channel configuration possible for different voltage ranges?
Yes, each of the eight channels can be independently configured for either 0-10V or ±10V range through MasterLogic-200 programming software, providing maximum flexibility for mixed sensor types.

Does the module support hot-swapping during system operation?
While physically possible, we recommend proper shutdown procedures before module removal or installation to prevent data corruption and ensure system stability. Consult your MasterLogic-200 system documentation for safe maintenance procedures.

What is the typical scan time for all eight channels?
Each channel converts in ≤100ms, so scanning all eight channels sequentially requires approximately 800ms. Actual update rates depend on your PLC program scan cycle and data processing requirements.

Are replacement modules backward compatible with older MasterLogic-200 systems?
Yes, the 2MLF-AV8A maintains backward compatibility with legacy MasterLogic-200 installations. Verify your system firmware version supports the module's features by consulting Honeywell compatibility documentation.
