1. Product Title

ABB 70BA01C‑S‑ Bailey Digital Input Module

2. Product Overview

70BA01C‑S is a digital input module for ABB Bailey INFI‑90 DCS system. It collects discrete on‑off status signals from field limit switches, interlock contacts and plant‑status sensors, transferring data to DCS controller through INFI‑90 backplane bus. Channel‑level galvanic isolation prevents field‑side noise and fault propagation into the DCS rack. Designed for continuous long‑term operation in power‑plant and process‑industry environments, it serves as direct replacement spare for discrete signal acquisition failures within INFI‑90 control racks.
