Description

Product Overview

The IMMFP03 (MFP03) is the early‑generation multifunction controller for ABB Bailey INFI 90, serving as the core control engine inside the PCU rack. It executes function‑block control logic, closed‑loop regulation, sequence control, batch logic and mathematical calculations, and communicates with all slave I/O modules over the slave bus. It can be configured as redundant primary/backup hot standby to guarantee uninterrupted process control during controller failure. It commonly pairs with IMMPI01 for serial programming and host connection. It is widely stocked legacy spare for power, pulp & paper, chemical and refinery DCS retrofits.
