Description
The EMERSON VE3008 (12P6381X032 / KJ2005X1-MQ1) is a powerful MQ Controller module for the DeltaV™ Distributed Control System (DCS). This controller provides the processing platform for executing control logic and managing communication between the DeltaV network and I/O subsystems. Designed for high availability and modular expansion, the MQ Controller supports “plug-and-play” installation and is capable of handling complex control strategies, including advanced regulatory control and batch processing, while maintaining robust performance in demanding industrial environments.

Application Fields
The EMERSON VE3008 is the standard control unit for medium-to-large scale operations across various process industries:
- Chemical & Specialty Chemicals: Precise control of reactor temperatures, pressures, and catalyst feeds.
- Pharmaceuticals: Executing complex batch recipes and maintaining strict regulatory compliance (21 CFR Part 11).
- Oil & Gas Refining: Managing distillation columns, crackers, and blending operations.
- Food & Beverage: Automating CIP (Clean-In-Place) cycles and high-speed filling lines.
- Pulp & Paper: Coordinating the operations of digesters, bleach plants, and paper machines.
Product Operation Instructions
- Mounting: Snap the MQ Controller into the assigned slot on a DeltaV 2-wide or 4-wide carrier. Ensure the module is fully seated and the locking levers are engaged.
- Network Wiring: Connect the Primary and Secondary control network cables (RJ-45) to the respective ports on the carrier. This ensures the controller can communicate with the DeltaV workstations and other controllers.
- Commissioning: Once powered, the controller will appear in the DeltaV Explorer “Decommissioned Nodes” list. Right-click and select “Commission” to assign it a node name and download the initial hardware configuration.
- Logic Download: Use DeltaV Control Studio to develop your control strategies. Once validated, perform a “Download” to transfer the functional logic to the controller’s memory.
- Redundancy Setup: If using a redundant pair, ensure both modules are identical in hardware and firmware revision. The secondary controller will automatically synchronize its database with the primary.
Q&A: Common Questions
Q: What is the difference between the KJ2005X1-MQ1 and the earlier M5 or MD controllers? A: The MQ (and later MQ Plus) provides significantly more processing power and memory than the legacy M5 series, allowing for larger I/O counts and more complex control modules within a single node.
Q: Does this controller support “Hot Swapping”? A: Yes, in a redundant configuration, the standby controller can be replaced while the system is powered and the primary controller is running the process.
Q: Can I use this controller with wireless I/O? A: Yes, the MQ Controller is fully compatible with the DeltaV Wireless I/O Card (WIOC), allowing for the integration of WirelessHART devices into your control strategy.
