Product Overview

The CP461-10 (Model: CP461-10) is a high-availability control processor module designed as the computational core for Yokogawa’s CENTUM VP and CS 3000 Distributed Control Systems (DCS). Specifically engineered for integration into AFV300 and AFV400 Field Control Units, the CP461-10 (Style S1) executes complex regulatory control functions and advanced automation strategies with high-speed precision.

To ensure continuous plant operation, the CP461-10 (Part Number: CP461-10) utilizes a dual-redundant architecture. In a synchronized setup, the primary and secondary modules cross-check data in real-time. If the primary unit detects a hardware or logic fault, the secondary processor assumes control through a "bumpless" transfer, preventing process upsets. This fault-tolerant design is critical for industries where unplanned downtime results in significant safety risks or production losses.
