VE3008
Product Overview
VE3008 (assembly part number KJ2005X1-MQ1) is the MQ Controller manufactured by Emerson for the DeltaV Distributed Control System. It is a rack-mounted high-performance process controller, installed inside DeltaV power/controller carrier chassis.
It executes continuous control strategies, sequence logic, alarm management and I/O data scheduling. Equipped with dual Ethernet control network interfaces, it supports redundant network topology and hot standby controller redundancy. It is compatible with traditional wired I/O subsystems and CHARM I/O, widely used in power plants, chemical plants and refineries for critical process automation.
