Description

Product Overview

The IMFEC12 is a 15‑channel high‑level analog input slave I/O card for ABB Bailey INFI 90 and Harmony Symphony DCS. It is designed for conventional 4–20 mA / voltage transmitters, without the FSK smart fieldbus capability of its sibling IMFEC11. It converts field analog signals into digital values and transmits data to MFP / MFC multifunction controllers over the slave bus. It can directly replace the older IMASI02. It pairs with termination assemblies such as NTFB01, widely used for pressure, flow and level monitoring in power, pulp & paper, chemical and refinery plants.
