Description

3BHE014070R0101 PPC905AE101: Product Overview
This processor module is a central processing unit designed for integration into ABB’s Bailey INFI 90 and Symphony Harmony distributed control system (DCS) architectures. It serves as the computational engine for a control node, responsible for executing user-defined control strategies and managing all data traffic between the node’s associated I/O modules and the plant-wide communication network. The module is a critical component in applications requiring high reliability, such as power generation, oil and gas, and chemical processing.
Its core functionality involves the execution of control algorithms, including regulatory loops and sequential logic, based on data acquired from field instruments. It processes analog and discrete signals via connected S800 I/O modules and facilitates communication with operator stations, engineering terminals, and other networked controllers using protocols like S9001. As part of the Bailey INFI 90 family, the module benefits from a platform renowned for its robustness and long service life in demanding industrial environments. The system’s modular design allows for scalable configurations, and the availability of redundant processor options enhances system availability, which is essential for maintaining continuous process operation.

Core Features & Customer Value
Redundant Operation Capability: The module supports dual-redundant configurations, where two units operate in a hot-standby arrangement. For the customer, this means that a processor failure will not cause an interruption in control, thereby increasing plant safety and preventing costly downtime.
Enhanced Processing Performance: Equipped with a 32-bit RISC processor operating at 200 MHz, the module can execute complex control logic and manage large volumes of I/O data efficiently. This allows engineers to implement advanced process control strategies and maintain stable operation under varying process conditions.
Integrated Communication Interfaces: Featuring multiple serial and Ethernet ports, the module provides flexible connectivity options for integration with legacy systems and modern network infrastructures. This simplifies the consolidation of data for supervisory systems and reduces the need for additional protocol conversion hardware.
Industrial-Grade Reliability: Designed for operation in a 0°C to +60°C temperature range and high humidity environments, the module can be mounted in standard control room panels. Its rugged construction minimizes the risk of failure due to environmental factors, contributing to lower maintenance requirements.

Typical Applications
The processor module is commonly deployed in power generation facilities, particularly in fossil fuel and combined-cycle plants. It is used to control balance-of-plant systems, including boiler feedwater pumps, cooling tower fans, and flue gas desulfurization units. In these settings, its redundant configuration ensures continuous operation of auxiliary systems critical to turbine and boiler efficiency.
In the oil and gas sector, the module is found in compressor station control applications, where it manages the starting, stopping, and loading of gas turbines or electric motors driving pipeline compressors. It also sees use in refinery units, such as crude distillation columns, where it regulates temperatures and pressures to maintain product quality. Another application is in large-scale water treatment plants, where it coordinates the operation of filtration systems, chemical dosing pumps, and remote pumping stations.
