Description

Product Overview

The IMCIS12 is a mixed analog & digital slave I/O card for ABB Bailey INFI 90 and Harmony Symphony systems. It handles A/D and D/A conversion and exchanges process data with multifunction controllers over the slave bus. It integrates a compact set of analog and discrete points for small control loops, such as valve modulation, feedback, interlock and alarm signals. It pairs with termination units NTAI06 / NTDI05 for field wiring. The functionally similar IMQRS12 is the quick‑response version with much faster analog sampling speed. It is widely stocked as legacy spare for power, pulp & paper, chemical and refinery DCS systems.
