Honeywell 2MLF-AD8A Analog Input Module

The Honeywell 2MLF-AD8A is an 8-channel analog input module engineered for the MasterLogic-200 PLC platform. It converts continuous field voltage and current signals into high-resolution digital values for process monitoring and control, featuring conformal coating for protection in harsh industrial operating conditions.

Signal Processing and Range Configuration

The module supports 8 independent analog channels configurable for standard voltage or current inputs. Available voltage spans include 1-5 V, 0-5 V, 0-10 V, and -10 to 10 V, while current spans cover 0-20 mA and 4-20 mA. Analog signals are converted into a 1/16000 digital output resolution with a fast conversion speed of 250 us per channel.

Digital conversion data can be formatted as signed integer values, precise values, percentile representations, or 14-bit binary values depending on application requirements.

Setup and Diagnostic Capabilities

Channel configuration is managed via physical DIP switches combined with setup options in SoftMaster software. For enhanced operational stability, the module includes automatic input disconnection detection to alert control systems of broken field wiring or sensor signal loop failures.
