Product Overview

The DSDI130 is a specialized Analog Input Unit belonging to the ABB S100 I/O series, designed for high-fidelity signal acquisition within Distributed Control Systems (DCS). This module serves as a precision interface, converting continuous physical variables from the field—such as pressure, temperature, and flow—into digital data for the controller. Engineered to maintain signal integrity in electrically noisy environments, the DSDI130 utilizes sophisticated filtering and galvanic isolation to prevent ground loops and interference. Its architecture is optimized for the MasterPiece 200 and Advant OCS systems, providing a reliable pathway for critical process variables that require high-resolution sampling and deterministic processing.
