ABB DSAI130A 3BSE018292R1 8‑Channel Analog Input Module

ABB DSAI130A 3BSE018292R1 is a hot‑swappable analog input module for ABB Advant Master DCS system. It collects 4‑20 mA analog field signals from transmitters, pressure sensors and flow instruments, converts analog signals into digital data and transmits to controller through rack backplane bus for real‑time process monitoring and closed‑loop calculation.

This 8‑channel module provides galvanic isolation between field side and system bus, supports per‑channel fault diagnosis for loop break detection. Equipped with front‑channel LED status indicators, it supports hot‑swap online replacement without rack shutdown. It is widely used as replacement spare‑part for on‑site troubleshooting, equipment maintenance and DCS system retrofit projects.
