Product Description
The SCP461-51 (E1 Suffix) is a high-availability central processing unit for the Yokogawa CENTUM VP distributed control system. Designed for AFV30S and AFV40S Field Control Units, it serves as the primary intelligence for executing process control logic and high-speed data acquisition.
This module supports dual-redundant “Pair & Spare” configurations, ensuring that a single hardware failure does not interrupt plant operations. Optimized for Vnet/IP communication, the SCP461-E1 handles high-density I/O management with deterministic scan rates, making it critical for large-scale industrial automation.
