Main Functions Collect multi‑channel differential analog signals from field transmitters. Perform signal filtering, surge protection and 12‑bit A/D conversion. Transfer converted digital measurement data to Advant controller through VME back‑plane bus. Support channel‑level diagnosis for transmitter open‑circuit and signal over‑range fault detection. Front‑panel LED indicators display power‑on status and hardware fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects internal circuit faults and reports fault information to the controller. Parameter configuration and channel debugging are completed by ABB Advant engineering software.

Installation Requirement Plug‑in installation inside Advant VME controller subrack. Analog signal cables shall adopt shielded twisted‑pair and be strictly separated from high‑power power cables. Ensure reliable cabinet protective grounding. After module replacement, confirm full part‑number DSAI130D / 3BSE003127R1 matches original project configuration, download complete system configuration file. Perform channel point‑to‑point signal‑loop test and calibration verification. Different hardware revisions cannot be directly interchanged without configuration adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Analog‑input‑module spare part for ABB Advant OCS / MasterPiece AC400 automation‑control systems; widely used for process‑signal acquisition in thermal‑power plants, hydropower plants and petrochemical industries; applied for legacy DCS‑PLC system maintenance and spare‑part replacement.

Key Features

1. 16‑channel differential analog input module for legacy Advant systems, compatible with voltage and current transmitter signals.
2. Group galvanic‑isolation design, suppress ground‑loop and electromagnetic interference in industrial environments.
3. Channel‑level fault diagnosis function, facilitating fast field‑loop fault location.
4. VME Eurocard plug‑in structure, back‑plane powered, convenient for on‑site replacement and maintenance.
5. Strict full‑part‑number matching required for spare‑part replacement; cannot be directly substituted by DSAI130 or DSAI130A without configuration adaptation.
