ABB AI880‑1 3BSE028587R1 Analog Input Module

The ABB AI880‑1 3BSE028587R1 is a high‑precision analog input module designed for ABB AC 800M DCS control systems. It collects analog process signals from field transmitters, converts analog signals into digital data, and transmits process values to the controller for closed‑loop regulation, monitoring and alarming in process industries.

This rack‑mount I/O module supports multiple signal types and channel‑level fault diagnostics for field circuit detection. Original production has been discontinued. It is widely used as aftermarket spare parts for chemical, power and pulp‑paper plant DCS cabinet maintenance and system upgrade projects.
