Core Information of CP451-10
CP451-10 is a key component in Yokogawa’s CENTUM VP Vnet/IP FIO (Fieldnetwork I/O) System,
functioning as a supporting module for Field Control Units (FCUs) and Node Units. It integrates with
the system’s redundant communication buses (ESB/Optical ESB/ER) and power supply
configurations, ensuring stable operation of I/O modules and field signal processing in industrial
control scenarios.
●Model Number: CP451-10
●Product Series: CENTUM VP Vnet/IP FIO System
●Core Function: Supports the operation of Field Control Units (AFV10/AFV30/AFV40) and Node
Units (ANB10/ANB11/ANR10), facilitating power distribution and bus communication
coordination for I/O modules.
●Key Feature: Compatible with dual-redundant configurations, adhering to the system’s high-
reliability design requirements for industrial control.
●Application Scope: Industrial automation environments (including non-hazardous and hazardous
locations with explosion protection modules), suitable for process control, turbomachinery
monitoring, and other industrial scenarios.
