The ABB PM665 (3BDS005799R1) is a PowerPC-based processor module designed for the Advant Controller 160 platform within ABB’s Advant OCS with Master Software control system. It serves as the central processing unit for high-availability industrial automation applications, executing control logic and managing system resources with deterministic performance.
System Context: Advant Controller 160
The Advant Controller 160 is a highly modular controller within the Advant OCS family, engineered for applications that demand high availability and redundancy. It is deployed in critical process control environments, including burner management, safety systems, and turbine control, where continuous operation and fault tolerance are essential. The PM665 operates as the computational core of this controller, running application programs and coordinating I/O communication.
Module Function and Architecture
The PM665 is built on a PowerPC processing architecture, delivering the computational throughput required for complex regulatory and logic control tasks. Its key functional characteristics include:
Redundancy Voter: The module integrates an onboard redundancy voter, enabling dual-processor hot-standby configurations. Two PM665 modules can operate in a redundant pair within a single station, synchronizing via a high-speed serial link to ensure seamless failover without process interruption.
High-Speed Link: A dedicated high-speed link facilitates synchronization between redundant processors and supports deterministic data exchange within the controller rack.
Speed Input: The module includes dedicated speed input channels, designed for rotational speed monitoring in turbine and machinery control applications.
These features position the PM665 as a suitable choice for applications requiring both high-performance processing and fault-tolerant operation.
Technical Specifications
According to ABB product data, the PM665 module has the following physical characteristics:
Dimensions: 252 mm (depth) × 273 mm (height) × 40 mm (width)
Net Weight: 2.04 kg
