Description
Product Description
Overview
The SCP461-E1 processor module, part of the Yokogawa CENTUM VP series, delivers high-reliability performance for distributed control systems. Designed for AFV30 and AFV40 Field Control Units, this module acts as the central processing unit, managing process control logic and high-speed data acquisition with deterministic performance. Its dual-redundant "Pair & Spare" configuration ensures plant operations continue without interruption in case of a hardware failure.
