57120001-DP DSAI 110 ABB Advant OCS Analog Input Board

Product Overview

The ABB DSAI 110, part number 57120001-DP, is a specialized analog signal acquisition module designed for the S100 I/O system within the Advant OCS (Open Control System) framework. This module is engineered to provide high-resolution conversion of field-level analog signals into digital data, facilitating precise process regulation and monitoring. As a core component of the MasterPiece 200/1 and Advant Controller 400 series, the DSAI 110 supports multiple input channels, each capable of handling standardized voltage and current ranges. Its high-speed processing capabilities and integrated filtering ensure that raw data from pressure, flow, and temperature transmitters are delivered to the controller with maximum fidelity and minimal latency, even in electrically volatile industrial environments.
