3BDH000357: Product OverviewThe 3BDH000357 is a high-performance controller module within ABB’s AC 800M series, designed 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, and advanced process optimization. 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.

Core Features & Customer ValueThe controller’s high-performance processor provides substantial computational power for complex control strategies including multi-variable predictive control, custom algorithms, and sophisticated sequencing logic. For process engineers, this enables implementation of advanced control schemes that improve process stability, product quality, and energy utilization. The deterministic execution ensures consistent control loop performance, which is critical for maintaining process variables within tight tolerances in continuous process industries.Integrated support for redundant configuration provides exceptional system availability for critical processes. The automatic failover capability ensures continuous operation during maintenance or component failure, significantly reducing unplanned downtime. The controller’s cybersecurity features, including user authentication, audit trails, and communication encryption, protect against unauthorized access and cyber threats, which is increasingly important in modern industrial operations.Typical ApplicationsIn chemical processing plants, the 3BDH000357 executes batch recipes for reactor control, managing precise temperature and pressure profiles while coordinating material addition and product transfer sequences. The batch management capabilities ensure recipe consistency and regulatory compliance.In power generation facilities, the controller manages turbine control, boiler management, and balance-of-plant systems. The wide operating temperature range makes it suitable for installation in both control rooms and field enclosures where environmental conditions may vary.
