Emerson SE3008 KJ2005X1-SQ1 12P6383X032 | DeltaV SQ Controller

Technical Specifications

The published technical data for this exact identification confirms the 5 VDC/1.4 A LocalBus power specification and -40 to +70°C operating range.

Product Overview

The Emerson SE3008 KJ2005X1-SQ1 12P6383X032 is an SQ controller for the DeltaV S-Series distributed control system, intended for small-to-moderate process-control applications. It provides the controller-level processing required to execute DeltaV control strategies while communicating with I/O and other nodes in the control architecture. The SQ platform supports automatic I/O detection and self-addressing, reducing configuration work during installation and commissioning.

The Emerson SE3008 KJ2005X1-SQ1 supports CHARM-based Electronic Marshalling, allowing field signals to be assigned through the DeltaV architecture rather than being constrained by a traditional fixed channel-to-controller arrangement. The SQ controller also supports 1:1 redundancy, making it suitable for applications where controller availability is important.

The Emerson 12P6383X032 designation is important because the SE3008 family has multiple hardware and ordering configurations. Procurement should therefore retain all three identifiers—SE3008, KJ2005X1-SQ1, and 12P6383X032—when specifying a replacement.

Main Features & Field Considerations

DeltaV SQ controller architecture
The SE3008 is a controller, not a conventional I/O card. It executes control strategies and manages communication between DeltaV I/O and other control-network nodes.

CHARM Electronic Marshalling support
The controller supports DeltaV’s CHARM-based Electronic Marshalling architecture. This is significant in systems where field wiring and I/O assignments were designed around CHARM technology.

1:1 redundancy
The SQ platform supports redundant controller configurations. Emerson’s published description also states that a redundant SQ pair can be upgraded to an SX controller arrangement without redesigning the existing configuration, documentation, and hardware design.

Automatic I/O detection and self-addressing
These functions simplify controller commissioning and I/O integration. They are particularly useful during cabinet replacement or expansion where multiple DeltaV S-Series modules must be recognized by the controller.

Wide environmental range
The published specifications show an operating range of -40 to +70°C, with ISA S71.04 Class G3 airborne-contaminant compatibility and specified shock/vibration resistance.

Legacy configuration compatibility
The SQ controller can use control strategies and system configurations developed on earlier DeltaV systems, which can be valuable during plant upgrades and controller replacements.

Important Procurement Note

There is conflicting secondary-market information about the electrical supply for this part. Some listings describe the controller’s LocalBus requirement as 5 VDC at 1.4 A maximum, while another reseller page incorrectly presents a 24 VDC controller input specification. The more specific hardware documentation identifies 5 VDC at 1.4 A maximum as the LocalBus power rating, so the 24 VDC claim should not be used as the controller’s direct power specification without checking the actual installation architecture.

There is also conflicting information around the alternate part number. One listing associates the with 12P6383X022, while your supplied identifier is 12P6383X032. For procurement, I would use your exact 12P6383X032 marking and verify the hardware label before accepting an alternate.
