Product Introduction

The ABB PM864A 3BSE018161R1 is a high-performance processor unit for AC800M controller within 800xA automation system. It adopts 32-bit RISC architecture with large flash and RAM memory, supporting hot standby redundant configuration. It executes complex control logic, handles analog and digital signal processing, and communicates with S800 I/O modules and operator stations. Featuring fast deterministic computation, comprehensive hardware diagnostics and multiple built-in communication ports, it fits critical process control applications in power, pulp & paper, chemical and metallurgical industries.

Content Details

ABB PM864A 3BSE018161R1 works as the core CPU of AC800M control system. It runs user control programs, collects field measurement signals and sends control commands to S800 I/O via ModuleBus. Redundant pair installation supports bumpless switchover without process interruption when one processor fails. This processor integrates dual Ethernet and CEX bus interfaces for data exchange, parameter download and alarm transmission. Built-in self-diagnosis continuously monitors hardware status, memory and communication links, records fault events to accelerate maintenance and reduce plant downtime. With rugged industrial mechanical design, the module provides excellent EMC immunity and stable operation under vibration and fluctuating temperature. PM864A is widely deployed in ABB 800xA DCS for continuous process plants. Before shipment, every unit undergoes full functional test and thermal aging inspection to eliminate hidden defects and guarantee reliable long-term continuous operation.
