The Yokogawa CENTUM family — spanning the original CENTUM V through CS 1000 and CS 3000 — represents one of the most widely deployed DCS architectures in heavy industry across Asia, the Middle East, and Europe. Many of these installations were commissioned in the 1990s and early 2000s and remain in active production service today. Yokogawa has progressively discontinued spare parts support for older CENTUM generations, leaving plant engineers to manage aging hardware without a reliable OEM supply chain.
How to extend the service life of a Yokogawa CENTUM system by 5 to 10 years:
Plants that follow this discipline consistently achieve 8 to 12 additional years of productive service from CENTUM installations that would otherwise be retired under financial pressure rather than technical necessity.
Every AKB335 unit supplied by DriveKNMS passes a structured 5-step incoming inspection before it is offered for sale.
Units that pass all five stages are issued a DriveKNMS inspection record and shipped with original or equivalent protective packaging.
Should I buy more than one unit?
For any CENTUM installation that is expected to remain in service for more than three years, holding a minimum of two AKB335 units is a reasonable position. Secondary market availability for obsolete Yokogawa cables is finite and decreasing. Units purchased today may not be available at the next procurement cycle.
