Yokogawa CP461-50 CENTUM VP Processor Module

Yokogawa CP461-50 is the high-performance processor module for CENTUM VP DCS system, deployed on AFV300 and AFV400 field control stations. It serves as the core controller to execute PID regulation, sequence control, interlock logic and process arithmetic calculations for continuous industrial production.

This module supports dual redundant hot standby configuration and zero-time automatic failover. It adopts Vnet/IP high-speed industrial network and built-in ECC memory. Widely used as spare replacement parts for petrochemical, chemical and power plant DCS control cabinets.
