1. Product Title

ABB 70BK03C‑E‑ Bailey Analog Input Module

2. Product Overview

70BK03C‑E is an analog input module for ABB Bailey INFI‑90 DCS platform. It receives 4‑20 mA analog measurement signals from field transmitters for pressure, temperature, flow and level variables, and converts analog field data into digital values for DCS control logic processing. Galvanic isolation between field channels and DCS backplane enhances noise immunity in heavy‑industry sites. Installed in standard INFI‑90 rack slots, it is a commonly used spare for process‑measurement acquisition faults in legacy Bailey DCS installations.
