IMFAI02 | 16-Bit Isolated Analog Input | ABB Bailey DCS

Product Description

High-Performance Data Acquisition Overview

The IMFAI02 (Model: IMFAI02) is a high-precision, isolated analog input module designed for the Bailey INFI 90 and Symphony Harmony Distributed Control Systems (DCS). Engineered for versatile field signal acquisition, the IMFAI02 (Part Number: IMFAI02) supports a wide array of industrial inputs including 4–20 mA current loops, 0–10 VDC voltage, thermocouples, and RTDs. With its 16-bit A/D resolution, this module provides the high granularity required for sensitive process variables. It features comprehensive channel-to-channel and channel-to-system isolation to eliminate ground loop interference, making it an essential component for maintaining high-availability legacy systems in power generation and chemical processing environments.
