1. General Introduction
AFV30S Field Control Unit features outstanding processing performance and a large application storage capacity, yet inherits the same quality and stability that are the hallmark of the CENTUM series. It compose of Processor modules CP461/CP471, power supplies PW482/PW481/PW484. Processor modules, power supplies, I/O modules, and communication buses all support redundant configuration. The latest release of the controller has been optimized to take full advantage of advancements in field digital technology that will help plants operate with increased efficiency and stability. A high speed remote I/O unit enables connecting controllers over remote site up to 50 kilometers via optical fiber cables.
