ABB PM802F | 3BDH000002R1 | AC 800F Processor Unit

Product Overview

The PM802F (3BDH000002R1) is a foundational processor module for the AC 800F controller system. Designed for rigorous industrial automation, it performs cyclic scanning, signal processing, and transmission to fieldbus actuators. The unit is engineered to support high-availability architectures, allowing for seamless controller redundancy—where a secondary unit can take over operations within milliseconds if the primary unit fails.
