HONEYWELL 2MLF-AD16A Analog Input Module

Overview

The HONEYWELL 2MLF-AD16A is a 16-channel analog input module for the Honeywell MasterLogic-200 PLC rack system. It converts field analog current or voltage signals into digital data for the PLC CPU. Each channel can be configured via DIP switches for 4–20 mA current or 0–10 V voltage input. It supports high-speed conversion at 500 µs per channel and features on-board diagnostic LEDs for channel status and fault indication. This module is widely deployed in DCS, process skids, chemical, power and water treatment automation systems for transmitter signal acquisition.

Features

The HONEYWELL 2MLF-AD16A provides 16 isolated analog input channels.2MLF-AD16A supports both 4–20 mA and 0–10 V signal types, selectable per channel. High sampling speed: 500 µs conversion time for each channel. Front panel RUN and fault LED indicators for status and trouble diagnosis. Screw terminal wiring, easy field wiring and maintenance. Rack backplane plug-in design, compatible with MasterLogic-200 CPU and power supply modules. Built-in overvoltage and reverse polarity protection for field circuits. Compliant with industrial EMC standards for control cabinet environments.

Specs

Device Type: Analog Input Module Model: HONEYWELL 2MLF-AD16A Brand: Honeywell Series: MasterLogic-200 PLC Channel count: 16 AI channels Signal types: 4–20 mA / 0–10 VDC (per channel selectable) Conversion speed: 500 µs per channel Resolution: 16 bit Isolation: Channel-group isolation Mounting: Rack plug-in Status: MasterLogic-200 spare I/O module

Principle

The HONEYWELL 2MLF-AD16A receives analog signals from field transmitters. Its internal ADC converts the analog value into digital data and transmits it to the MasterLogic CPU over the rack backplane bus. The CPU executes control logic based on the measured process variables.

Applications

The HONEYWELL 2MLF-AD16A is used to collect pressure, temperature, flow and level transmitter signals in chemical, power, metallurgy and water treatment process skids. The HONEYWELL 2MLF-AD16A is stocked as spare replacement for MasterLogic-200 PLC systems.
