Description

Product Overview

The ABB DSAX 110A 3BSE018291R1 is a high-precision analog interface module engineered for the Advant Controller 450 (AC450) and broader DCS environments. This dual-purpose board facilitates the simultaneous management of 8 analog input and 8 analog output channels, providing a centralized solution for sensor monitoring and actuator control.²

Comprehensive Analog Signal Processing

The DSAX 110A serves as a critical bridge between field instrumentation and the central processing unit of a Distributed Control System. By supporting 8 dedicated input channels and 8 output channels, this module allows operators to monitor variables such as pressure, temperature, and flow while simultaneously sending corrective signals to control valves or variable speed drives.³ This bidirectional capability ensures tight control loops and high-fidelity data acquisition. Furthermore, the board utilizes advanced filtering technology to mitigate electrical noise, which preserves signal integrity even in electromagnetically noisy industrial settings.

Seamless System Integration and Reliability

ABB designed the 3BSE018291R1 specifically for the AC450 range, ensuring native compatibility and simplified software configuration. Because the module features a hot-swappable architecture, maintenance teams can replace units without requiring a complete system shutdown, significantly reducing potential downtime. The board’s slim, vertical form factor optimizes rack space, allowing for high-density I/O configurations within standard control cabinets. Additionally, integrated diagnostic LEDs provide real-time status updates, empowering technicians to identify and resolve channel faults immediately.

Durable Design for Process Automation

Manufactured in Sweden to exacting standards, the DSAX 110A is built to withstand the rigors of continuous 24/7 operation in sectors such as power generation, chemical processing, and pulp and paper. The robust PCB coating protects internal circuitry from humidity and airborne contaminants, while the high-quality gold-plated connectors ensure long-term mechanical stability. By implementing this genuine ABB component, facilities achieve higher automation accuracy and improved process safety through reliable, standardized hardware.
