ABB PM665 3BDS005799R1 Processor Module
ABB PM665 (3BDS005799R1) is a PowerPC-based high-performance processor module for ABB Advant Controller 160 / Advant Master DCS system. It integrates redundancy voter, high-speed link and speed input interface, acting as the central core to execute control algorithms and coordinate system communication.



This module supports dual lockstep redundant architecture and SIL2 safety capability, with built-in comprehensive self-diagnosis. It connects to I/O racks and plant supervisory systems, widely deployed in power, pulp & paper and petrochemical process control. It is discontinued, supplied as surplus or refurbished spare parts for system replacement.

FAQ
| No. | Question & Answer |
|---|---|
| 1 | Q:What is ABB PM665 3BDS005799R1? A:It is the core processor module of ABB Advant AC160 DCS. Built on PowerPC with lockstep redundancy, it executes control logic, handles I/O communication and collects speed signals for continuous process industries. |
| 2 | Q:What is lockstep redundancy? A:Dual CPUs run identical instructions synchronously, and the voter compares outputs in real time. If discrepancy occurs, the system triggers fault alarm to avoid silent failure and meet SIL2 safety requirement. |
| 3 | Q:Is ABB PM665 3BDS005799R1 still in production? A:This processor module has been discontinued by ABB. Available products are new surplus or refurbished spare parts for existing Advant Master DCS system maintenance. |
