UAC346AE01 HIEE300831R1 ABB Bailey Central Control Unit

Product  Description：

• • • The Central Control Unit is a robust, industrial-grade hardware module designed to operate reliably in demanding process environments. It houses the main processor, memory, and communication interfaces necessary to manage a defined portion of the plant's control architecture. The CCU is typically installed in a control cabinet and connects to various I/O modules, field devices, and network links.

       

      Key Functions

       

      • Process Control Execution: Executes user-programmed control strategies, logic, and algorithms for a specific plant area or process unit.

      • I/O Management: Interfaces with and processes inputs from a wide range of digital and analog I/O modules, and commands outputs to field devices.

      • Communication Hub: Manages communication within its local node and exchanges data with other CCUs, operator workstations, engineering stations, and other system components via the DCS network.

      • Data Acquisition: Collects process data from connected I/O modules for monitoring, alarming, and logging.

      • Alarm Management: Processes alarm conditions from I/O and control logic, relaying them to operator interfaces.

       

      Product Parameters (Typical)

       

      Specific parameters vary by model (e.g., older Bailey INFI 90 vs. newer 800xA system controllers that might fulfill similar roles). However, general characteristics include:

      • Processor Type: Industrial-grade microprocessors (e.g., Motorola, Intel-based).

      • Memory: RAM for program execution and data buffering, ROM/Flash for firmware and non-volatile program storage.

      • Communication Interfaces:

        • Network Ports: Redundant Ethernet ports (e.g., 10/100 Mbps) for communication with other DCS nodes (e.g., ControlWay, Fieldbus).

        • Serial Ports: RS-232 or RS-485 for local configuration, diagnostics, or interfacing with specific devices.

        • I/O Bus Interface: Dedicated interface for connecting local I/O modules.

      • Power Supply: Redundant DC power inputs for high availability.

      • Operating Temperature: Wide industrial range (e.g., -20°C to +70°C).

      • Humidity: Typically 5% to 95% non-condensing.

      • Enclosure: Rack-mounted module within a controlled cabinet.

      • Software Environment: Runs proprietary real-time operating systems and control configuration software (e.g., Bailey Systems Platform, ABB 800xA).

       

      Product Advantages

       

      • High Availability: Redundant hardware (CPU, power supply, network) and robust software design ensure continuous operation for critical processes.

      • Scalability: The modular design allows systems to be scaled up or down by adding or removing CCUs and I/O modules as needed.

      • Reliability: Built for harsh industrial environments, ensuring dependable performance in demanding conditions.

      • Powerful Control Capabilities: Supports complex control algorithms and logic for sophisticated process automation.

      • Integrated System: Designed to be part of a cohesive DCS, offering seamless integration, common engineering tools, and unified system management.

      • Global Support: As part of ABB's extensive product line, it benefits from widespread technical support and expertise.

       

      Precautions

       

      • Environment: Ensure the CCU is installed in an environment within its specified operating temperature and humidity range, free from excessive dust, vibration, and corrosive elements.

      • Power Supply: Use only approved and properly rated redundant power supplies. Incorrect power can lead to module failure.

      • ESD Protection: Handle the modules with extreme care, following proper electrostatic discharge (ESD) prevention procedures during installation and maintenance to avoid damage to sensitive electronic components.

      • Configuration and Programming: Control logic and configuration must be developed and tested meticulously by qualified engineers using the specific ABB Bailey software tools. Errors can have significant operational consequences.

      • Network Integrity: Maintain the integrity of the DCS network cabling and connections to ensure reliable communication between CCUs and other system components.

      • Firmware Updates: Plan and execute firmware updates carefully, understanding compatibility requirements and potential downtime.

      • Legacy Systems: Be aware that older Bailey systems (e.g., INFI 90) may have specific maintenance and support considerations as they age.

       

      Product Applications

       

      ABB Bailey Central Control Units are widely employed in industries requiring robust and reliable process control, including:

      • Power Generation: Control of boilers, turbines, balance of plant systems, and emissions control.

      • Oil and Gas: Upstream, midstream, and downstream processes, including refineries, petrochemical plants, and offshore platforms.

      • Chemical Industry: Process control for various chemical manufacturing operations.

      • Pulp and Paper: Control of paper machines, chemical recovery, and water treatment.

      • Mining and Metals: Automation for processing plants and material handling.

      • Water and Wastewater Treatment: Management of treatment processes and distribution systems.
