ABB 3BHB004791R0101 Controller Module High Quality

ABB 3BHB004791R0101 Control Processor Module (PM866 Series)

Product Overview

The ABB 3BHB004791R0101 is a high-performance control processor module within the PM866 series, engineered for ABB’s AC 800M distributed control system (DCS). Designed for real-time industrial automation and process control, it serves as the core computational unit in complex environments such as oil & gas, power generation, chemical processing, and smart manufacturing.

Powered by a dual-core ARM Cortex-A9 processor, this module executes control logic, safety functions, and data processing with sub-millisecond cycle times. Its support for up to 1,000 I/O points via S800 I/O racks ensures broad application coverage, while seamless integration with ABB’s 800xA system enables intuitive engineering, simulation, and commissioning from a unified interface.

Key Features

High-Speed Processing & Redundancy

• Dual-core architecture enables simultaneous execution of control loops, PID functions, and safety interlocks—ideal for applications like high-speed packaging lines or chemical batch control.

• Optional dual-processor redundancy allows automatic failover, ensuring zero process interruption in critical systems like offshore platforms.

Advanced Cybersecurity & Connectivity

• Features secure boot and AES-256 encrypted communications for protection against unauthorized firmware modification and cyber threats.

• Supports PROFINET and Ethernet/IP via dual Ethernet ports for interoperability with third-party devices such as Siemens drives or Rockwell PLCs.

• Enables real-time integration with MES systems and ABB Ability™ analytics, facilitating predictive maintenance and production optimization.

Scalability & Ease of Use

• Modular design allows incremental system expansion with additional I/O racks or gateways.

• ABB Control Builder M software supports drag-and-drop configuration, rapid diagnostics, and visual programming—reducing deployment time by up to 40%.

• Suitable for complex, multi-function systems such as pharmaceutical plants, where one module can control HVAC, sterilization, and batch processing operations.
