Emerson DeltaV KJ2005X1-SQ1 SQ Controller

Product Overview

The Emerson KJ2005X1-SQ1 (also known as SE3008) is the DeltaV™ SQ Controller, a compact, scalable control platform for small to moderate process applications. It provides communication and control functions, integrates field devices, and supports CHARM-based Electronic Marshalling. The SQ Controller offers a cost-effective alternative to larger SX controllers while maintaining full DeltaV compatibility.

Installation Guide

1. Install the controller on a 2-wide Power/Controller Carrier in the DeltaV chassis.
2. Connect dual RJ-45 Ethernet cables to primary and redundant control network segments.
3. Ensure +5 VDC local bus power is available at 1.4 A maximum.
4. Use DeltaV Explorer to auto-detect the controller and download configuration.
5. For redundancy, install a second SQ Controller in the adjacent slot and configure 1:1 redundancy.

FAQ

• Q: What is the difference between SQ and SX controllers?
  A: The SQ is a smaller, cost-effective controller for moderate applications; the SX offers higher capacity. SQ can be upgraded to SX online without changing configuration.
• Q: Does it support CHARMs I/O?
  A: Yes, the SQ Controller fully supports CHARM-based Electronic Marshalling, a key feature of DeltaV S-Series.
• Q: Can I upgrade from an MD or MQ controller to SQ?
  A: Yes, the SQ replaces MD/MD Plus and MQ controllers while retaining existing configuration and hardware design.
• Q: What firmware version is required?
  A: DeltaV v10.3 or later is recommended for full compatibility and feature support.

Selection Tips

• Choose the SQ Controller for small to medium-sized process units where cost and footprint are critical.
• Plan for 1:1 redundancy in mission-critical loops to ensure zero-interruption failover.
• Verify control network infrastructure supports dual 100 Mbps Ethernet for primary and redundant paths.
