Sourcing Hard-to-Find & Obsolete Ovation Parts

A significant portion of the global Ovation installed base operates on hardware that Emerson has classified as End-of-Active-Support or End-of-Life. Power generation facilities with 20–40 year operational horizons cannot execute full DCS migrations on short notice; the capital expenditure, engineering validation, and regulatory approval cycles for nuclear and refinery applications routinely span 5–10 years. During this interval, facilities require a reliable supply of original hardware to maintain system integrity.

Quality Control for the Ovation Range

Ovation KJ-series modules present specific test challenges due to their integrated backplane communication logic and multi-layer PCB construction. DriveKNMS applies a structured verification protocol to all Ovation modules prior to dispatch:
