Description

ABB DSAI130A (3BSE018292R1) 16‑Channel Differential Analog Input Module for Advant OCS S100 I/O System

 

Product Introduction

The ABB DSAI130A, factory part number 3BSE018292R1, is a high‑density differential analog input board within the ABB Advant S100 I/O family. It converts continuous analog field measurements into digital signals for the Advant OCS main controller. This module supports flexible channel configuration: full 16 differential inputs, or a mixed mode of 8 differential plus 8 single‑ended channels. Featuring excellent common‑mode noise rejection, it delivers high‑precision sampling for long cable field transmitters. Communicating over the native S100 backplane bus, it is widely deployed on legacy Advant MOD300 / AC460 control racks and also compatible with AC 800M via CI856 interface. As a mature spare I/O board, it is commonly stocked for plant preventive maintenance and emergency replacement of aging DCS systems.

Specific Application Information

  • Process variable acquisition: Collect 4‑20mA / ±20mA, ±10V signals from pressure, temperature, flow and level transmitters.
  • Differential signal sampling: Capture low‑level analog signals from remote field instruments with long wiring distance.
  • Closed‑loop control feedback: Provide real‑time measured values for PID regulation loops in continuous production processes.
  • Vibration & condition monitoring: Acquire analog sensor signals for rotating machinery auxiliary monitoring points.
  • Water quality parameter measurement: Receive analog output signals from online water analyzers in wastewater plants.
  • Furnace and boiler parameter monitoring: Sample steam pressure, flue gas temperature and water level sensors in thermal power units.
