UAD155A0111: Product OverviewThe UAD155A0111 is a high-performance controller module within ABB’s AC 800M series, designed specifically for System 800xA distributed control system (DCS) applications. This module functions as the computational core of the control system, executing complex control strategies including regulatory control algorithms, batch sequencing, advanced process optimization, and safety instrumented functions. Installed in an AC 800M controller baseplate, it manages all controller operations, including scanning I/O modules via various fieldbus networks, executing application programs, handling communication with operator stations, and interfacing with higher-level systems.The controller operates as part of a modular system architecture where it coordinates with other modules in the controller chassis, including communication interfaces, power supply units, and co-processor modules. It runs the control application program developed with ABB’s Control Builder engineering tool, processing real-time data from field devices and executing control commands with deterministic performance. The controller’s design focuses on high availability, cybersecurity, and seamless integration for continuous process operations in demanding industrial environments.
